Drug delivery systems are characterized as formulations designed for the transportation of a drug to the targeted area of action within the body. The fundamental element of drug delivery systems is a suitable carrier that safeguards therefrom swift degradation or elimination, consequently increasing drugconcentrationin targeted tissues. Niosomes are promising drug carriers due to their biodegradable, biocompatible, and nonimmunogenic structure, which are created through the self-association of nonionic surfactants and cholesterol in an aqueous environment. In recent years, many research articles have been published in scientific journals highlighting the potential of niosomes to act as carriers for the delivery of various types of drugs. This review outlines preparation methods, characterization techniques, and recent studies concerning niosomal drug delivery systems and provides current information regarding recent applications of niosomes in drug delivery.
Niosomes are biodegradable, biocompatible, harmless, and capable of encapsulating large volumes of material into relatively smaller vesicles. It can be predicted that encapsulation of the drug in a vesicular construct will prolong the presence of the drug in systemic circulation and thus enhance diffusion into the target material and reduce toxicity [1]. The minuscule non-ionic surfactant vesicles known as niosomes have spherical, unilamellar, bilayer, multilamellar, and polyhedded shapes [2]. Niosomes formed by hydration are tiny lamellar structures that arise from the combination of non-ionic surfactants from the alkyl or dialkyl polyglycerol ether category with cholesterol. Their structure, which includes hydrophilic, amphiphilic, and lipophilic components, allows them to encapsulate drug molecules with different solubility profiles [3]. Due to poor water solubility, efflux by gut wall transporters, and first pass metabolism, oral administration of Biopharmaceutics Classification System (BCS) II drugs typically results in low and variable bioavailability. Numerous formulation techniques, including solid dispersions, Nano emulsions, Nano suspensions, and nanoparticles based on lipids and polymers have developed to get around these problems. Liposomes and niosomes share structural similarities [4]. Compared to widely utilized Nano systems, niosomes are potential nanocarriers with a number of benefits [5]. Niosomes represent a possibly effective method for delivering phytochemicals compounds, due to their limited solubility in bodily fluids. Different niosomes have been created to address the shortcomings of phytoconstituents [6]. Niosomes are stable against oxidation and hydrolysis processes, and hence, it improves the shelf life of the formulation [7]. In Niosomes, small size range of particles leads to high surface area available for drug absorption through the skin, and thereby provides greater efficacy. These nanocarriers help in formation of thin film on the skin and has occlusive effect with decrease in the [8]. For instance, the oral administration of repaglinide has faced criticism because of first pass metabolism, therefore diminished bioavailability. The necessity for prolonged repaglinide delivery is additionally supported by the need to keep stable plasma levels for the effective long-term control of blood sugar in diabetic individuals. Under these circumstances, transdermal drug delivery continues to be the preferred method of administration [9].
Figure 1.1: Structure Of Niosomes
METHOD OF PREPARATION:
The formulation of niosomes requires a combination of lipids and surfactants, which are hydrated at elevated temperatures. Subsequently, a size-reduction process is conducted to create a colloidal suspension. Several techniques utilized for the preparation of niosomes include the handshaking/thin-film hydration method, ether injection, microfluidization, and sonication. The handshaking/thin-film hydration method specifically entails dissolving surfactants and cholesterol in an organic solvent to produce niosomes [10].
In this method, surfactants and additional additives are uniformly dissolved in an organic solvent, such as chloroform or a combination of organic solvents, within a round-bottom flask. Subsequently, the solvent is entirely removed using a rotary vacuum evaporator, resulting in a thin film adhering to the inner surface of the flask. This thin film is then re-hydrated with an aqueous medium, which may consist of water or phosphate-buffered saline (PBS) that typically contains the drug intended for encapsulation. Upon completion of the rehydration process, niosomes of varying diameters are produced.
In this method, solvents like diethyl ether and ethanol are employed to dissolve surfactants and various additives. This homogeneous solution is subsequently transferred into a syringe pump, from which it is injected drop-wise through a needle into an aqueous solution maintained at a constant temperature exceeding the boiling point of the organic solvent. The residual organic solvent is entirely removed using a rotary vacuum evaporator. Throughout this evaporation process, unilamellar vesicular niosomes of varying sizes are formed, with a relatively greater entrapped aqueous volume compared to other techniques.
In the bubble method, niosomes are synthesized without the use of organic solvents. Surfactants and additives are combined in an aqueous medium, such as phosphate-buffered saline (PBS), and subsequently transferred to a three-neck round-bottom flask. This flask is then placed in a water bath to regulate the temperature. The dispersion of surfactants and additives occurs at a temperature of 70 °C. Initially, a high shear homogenizer is employed to achieve homogeneous dispersion by stirring for a duration of 15 to 30 seconds, after which nitrogen gas is bubbled through the solution at 70 °C [11].
Figure 2: Bubble Method
In this method, the carbohydrate carriers are loaded into the round bottom flask. Then the lipid components are dissolved in ethanol separately. Then these are directly infused into the carbohydrate carriers to form a slurry. The flask holding the alcoholic slurry is connected to the rotary evaporator and partially submerged in a water bath maintained at 45 °C. This setup facilitated the evaporation of ethanol through rotation and reduced pressure over a duration of 2 hours. Subsequently, the flask is positioned under the fume hood for an overnight period [12].
In this method, the lipid components are heated on a water bath at 60 ?C until uniformity is achieved. Then drug and aqueous solvent is heated on a water bath at 60 ?C. Then these mixtures are mixed with continuous stirring and finally it is subjected to probe sonication for about 5 minutes to form niosomes [13].
Figure 3: Probe Sonicator
The precise weights of Repaglinide, PhosphatidylCholine, Cholesterol, and Span 60 were dissolved in 2 mL of ethanol. A suitable quantity of preheated distilled water (at 60 °C), with or without Tween 80, was slowly added to the lipid solution in ethanol while stirring continuously with a magnetic stirrer. The stirring process was maintained at room temperature for 1 hour to ensure that all the ethanol was completely removed. This dispersion was subjected to sonication at room temperature for 10 minutes using a bath sonicator. Subsequently, this mixture was stored overnight in a refrigerator to allow the lipo niosomal hybrids to mature fully [14].
In molten form, 1.75 ml of surfactant (GMO) was used to dissolve 100 mg of quercetin. Following this, 12.5 ml of a 0.1% copolymer (poloxamer 188) was added gradually, and the mixture was sonicated for 3 minutes at a power of 18 W. To create the final nanoemulsion, a 2.4% solution of Eudragit S100 was incorporated into the initial emulsion. The resulting product was subjected to freeze-drying for 48 hours with percent mannitol serving as the cryoprotectant, resulting in a fine nanoparticle powder. The produced whitish lyophilized product was collected and stored at 4°C until required [15].
APPLICATIONS OF NIOSOMES
? Niosomal spreading in an aqueous segment can be mixed in a non-aqueous stage to administer the typical vesicle in external non-aqueous environment and regulate the medication's distribution rate.
? The vehicle suspension system is water-based. This suggests excellent patient compliance when using greasy dose forms for evaluation.
? Niosomes can hold drug particles with a variety of solubilities because of its infrastructure, which consists of hydrophilic, amphiphilic, and lipophilic molecules together. The vesicle preparation's characteristics are controllable and scalable.
? The vesicles can act as a reservoir, releasing the medication in a regulated manner.
? They possess osmotic energy and stability, and they enhance the reliability of encapsulated drugs.
? They enhance the oral bioavailability of medications that are poorly absorbed and boost the skin penetration of drugs.
? They can effectively distribute the site of action via oral, parenteral, and topical methods.
? The surfactants are recyclable, biocompatible, and non-immunogenic, making them safe for the formulation of Niosomes.[1]

Evaluation Studies:
Entrapment Efficiency:
By employing the ultra-centrifugation technique, the percentage of entrapment efficiency was assessed. A centrifuge was utilized to spin a niosome sample at a designated concentration for one hour at 4 °C. Following appropriate dilution, the resulting supernatant was analyzed to check for free drugs, and quantification was performed using the formula:
Entrapment Efficiency = A1 − A2/A1 × 100
Where A1 represents the concentration of herbal drug used in the loaded niosomes, and A2 indicates the concentration of drug believed to be present in the supernatant [16].
In-Vitro Drug Release:
The anti-diabetic effect was assessed in vitro by measuring the inhibition of α-amylase and DPP IV activity in the nanoparticles. The formulation achieved a peak inhibition of 82.06% for α-amylase and 94.73% for DPP IV, respectively [17].
Transmission Electron Microscope [Tem]:
The structure of niosomes was observed through TEM analysis. Samples were stained negatively with a 2% uranyl acetate solution. In addition to standard TEM analysis of the niosome samples, control niosome formulations were diluted further to prevent aggregation and to visualize individual particles. The samples were prepared using carbon-coated copper mesh and allowed to air dry at room temperature prior to measurements [18].
Zeta Potential:
Zeta potential is commonly used as a measure of a nanoemulsion system's stability. It is evident that increased stability is a result of higher zeta potential levels. However, the literature shows a wide range of values from 1.5 to 45.5 mV, therefore these values cannot be used only to assess stability. The detected zeta potential values ranged from -12.8% to -20.7 mV and were all negative. Electrostatic repulsion occurs in nanoemulsions with negatively charged droplets, promoting free coalescence and preserving a well-dispersed emulsion system [19]. After evaluation, the drug nanolipid carriers' zeta potential was determined to be -31.0 ± 2.13 mV [20]. The proniosomal powders were hydrated with phosphate buffer at a pH of 7.4 and subjected to bath sonication for 10 minutes. Following appropriate dilution, the resulting dispersion was analyzed for size and zeta potential using a Malvern Zeta Sizer System, version 6.02 [21].
In-Vivo Permeation Studies:
The antidiabetic effects observed in vivo suggest that niosomes formulated gel delivered the medication steadily over an extended duration, leading to sustained regulation of blood sugar levels for up to 48 hours [22].
Scanning Electron Microscopy [Sem]:
The structure of niosome emulgel formulation was assessed through scanning electron microscopy. The niosome emulgel was mixed with water at a ratio of 1:10. A small number of sample drops were placed on a stub that was coated with double-sided adhesive tape and allowed to dry before further processing and covered in gold for clarity. The image obtained by using SEM shows tiny, spherical vesicles dispersed throughout the macromolecular polymer network. There were no noticeable insulin crystals in the formulation, suggesting that the drug was highly soluble [23].
Ex-Vivo Permeation Studies:
Diffusion through rat skin was measured with a vertical Franz diffusion cell for 12 hours. Excised skin membranes were mounted in diffusion cells with the dermal side down in contact with receptor fluid. The receptor fluid was phosphate buffer saline with 10% Tween 80, pH 7.4 (PBS-T). The skin surface area available for drug absorption was 0.64 cm2. PBS-T was used in both donor (1 mL) and receptor (5 mL) compartments for pretest equilibrium. After this step, the fluid in the donor and receptor was withdrawn and a circular DIE patch was applied on the skin with light pressure to immobilize the device on the skin. The receptor compartment was filled with PBS-T. mixed at constant speed (600rpm) and maintained at a temperature of 37 ± 0.5 ?C using a circulating water bath. At certain time intervals, samples were collected and substituted with an equivalent volume of fresh PBS-T [24].
CONCLUSION:
In recent decades, nano and micro-sized vesicular drug delivery systems have attracted researchers\' attention. Most studies concluded that vesicular drug delivery systems could increase the stability of drugs that are sensitive to environmental conditions or particularly could protect them in harsh conditions of the GI tract for oral drug delivery. In addition, vesicular systems can increase the absorption of drug molecules with low absorption properties. Niosomes, the type of vesicular delivery system, do it with non -ions and active surfacing, were first developed for cosmetic and industrial use. Therefore, these vesicle systems are attractive to many researchers. However, in the case of anti -inflammatory drugs that include chemical and natural compounds. They mainly have problems with absorption and also have serious AE. In the future, these compounds will have many applications in the field of targeted drug delivery, especially in cancer, from their physical and chemical properties and biological effects natural compounds.
