Micelles can be thought of as a sheet folded back onto itself. Which way it folds depends on the surrounding medium. In an aqueous medium, a micelle has the hydrophobic chains on the inside with the polar heads on the outside. However, if the solvent is organic, then the components of the micelle are reversed—hence the name reverse micelle. The polar heads are interior, and the hydrophobic chains are exterior. Cartoons of a micelle and a reverse micelle are shown in Figure 4-8.3. Micelles. Schematic representation of a micelle in aqueous solution. Micelles are widely used in industrial and biological fields for their ability to dissolve and move non polar substances through an.. A micelle or micella is an aggregate of surfactant molecules dispersed in a liquid colloid. Micelle. Introduction. History. Solvation. Energy of formation. Micelle packing parameter Micelles/polymeric micelles are composed of amphiphilic macromolecules with a hydrophobic core and hydrophilic shell with the size ranging from 20 to 80 nm (Lu and Park, 2013). Traditional micelles are lipid-based. Basically, the hydrophilic heads of phospholipids forms the shell and the fatty acid tails of phospholipids forms the hydrophobic core of the micelle that can accommodate phytochemicals (Wang et al., 2014, p. 365). Polymeric micelles are emerging as a powerful tool in nanomedicine platform for cancer therapy due to their tunable size, in vivo stability, and efficiency in solubilizing water insoluble anticancer drugs with increased blood circulation times (Sutton et al., 2007, p. 1029). Other potent pharmacokinetic benefits include reduced systemic toxicity and patient morbidity. Functionalized micelles as a recent advancement play an important role in cancer therapy by site-specific drug release at the target site (Sutton et al., 2007, p. 1029). Micelles are more advantageous than liposomes owing to its rapid accumulation into tumors due to its smaller size (Weissig et al., 1998, p. 1552). Like liposomes, micelles can be conjugated or functionalized with carbohydrates, peptides, mAbs, aptamers, and polymers for targeting and improving the pharmacological behaviors of payloads (Liu et al., 2012, p. 2521).

The intestine is where fat is digested into monoglyerides and fatty acids. Micelles play important roles in the absorption of these two types of molecules. Micelles that form from these molecules flow to the surface of the cells that line the intestine. Micelles are constantly breaking and reforming, so when they break apart near the surface of the intestinal cell, the cell can absorb the fatty acids and monoglycerides. Since fatty acids and monoglycerides are nonpolar, they just diffuse through the cell membrane. Micelles also carry vitamins and cholesterol from digested food to these intestinal cells.

Molecules that have water-fearing tails and water-loving heads are called amphipathic molecules. They can form bilayers that sandwich the tails in the middle, or they can form spherical micelles. Phospholipids are amphipathic molecules that contain two water-fearing tails. Because two tails are present, overcrowding would be caused in the micelle formation. Thus phospholipids prefer to form bilayers. Fatty acids, however, have only one water-fearing tail, so forming a micelle is easier and more stable for them.Besides, the micelles depict little circulation time inside the body owing to their smaller size over liposomes. Furthermore, this gives them the benefit of being capable of entering the tumor cells more smoothly owing to the EPR effect. In addition, they can produce from polymeric molecules.

Fatty acids don’t readily form micelles until a certain concentration of fatty acids is present in a solution. Once the number of fatty acids reaches a concentration known as the critical micelle concentration (CMC), they will begin forming micelles. Above the CMC, adding more fatty acids will result in the formation of more micelles. Below the CMC, fatty acids prefer to form a layer at the surface of the water in which the water-fearing tails point up into the air and the water-loving heads stand on the water. backbone, micelles are in a state of thermodynamic equilibrium with the solvent and are perpetually 1998͔͒.

Polymeric micelles have attracted much attention in drug delivery because of their ability to solubilize hydrophobic molecules, their small particle size, good thermodynamic solution stability, extended release of various drugs, and prevention of rapid clearance by the reticuloendothelial system (RES). Low critical micelle concentration (CMC), is another key characterization parameter for polymeric micelles. The lower CMC values are advantageous for preparation of stable micelles. This is all the more important for pharmaceutical applications since a micelle having high CMC values may dissociate into unimers on dilution with a large volume of blood and thereby release the entrapped drug molecules. However, the micelles with low CMC values are more likely to remain the same even in a large volume of the blood.

Since the micelles formulated are thermoresponsive, it is essential to test the effect of temperature on the micelles and the degree of temperature sensitivity. The polyion complex micelles studied containing PNIPAM were hydrophilic in nature when the temperature was below the LCST and helped in protecting the micelles. However, an increase in the temperature lead to the micelles becoming poorly soluble, causing them to shrink and collapse to the core. So at a temperature of almost 33°C, the micelles were soluble as the outer shell and further large aggregates were produced [19].

Micelles consist of polymeric core–shell structures synthesized from amphiphilic block copolymers. Such self-assembled structures are formed as soon as the concentration of polymer in the solution reaches a certain threshold concentration, termed critical micellar concentration (CMC), in the presence of a certain threshold temperature termed critical micellar temperature (CMT) (Wakaskar, 2017). The average size of the polymeric micelles ranges from 10 to 100 nm. Micelles have some advantages over other nanocarriers like liposomes, as it is difficult and complicated to obtain liposomes less than 50 nm range. The size and morphology of the resultant micelles can be controlled by tuning the structure of the copolymers used for synthesis (Mourya, Inamdar, Nawale, & Kulthe, 2011). As micelles are single-layer structures, the core of the micelles remains hydrophobic, enabling entrapment of poorly soluble drugs in the core of micelles. This also enhances the solubility, improving the bioavailability and circulation time of drugs (Yokoyama, 2014).The fluidities of liquid-like cores may be investigated by comparisons of the mobilities of fluorescence185 and electron spin resonance186 probe molecules solubilized in micelles and in pure organic solvents. Use of NMR offers a method of studying the fluidity of micelle cores without the uncertainities introduced by the perturbing effects of probes.187–189 The occurrence of colloidally stable aggregates with crystalline cores formed by poly(oxyethylene) blocks is suggested by results obtained for a polystyrene-block-poly(oxyethylene) copolymer in ethylbenzene.190 Micelles formed by polystyrene-block-poly(oxyethylene) copolymers in water generally have glassy polystyrene cores at room temperature, but these become rubbery on heating above the Tg of the polystyrene blocks.191 Micelle formation is essential for the absorption of fat-soluble vitamins and complicated lipids within the Hartley, G.S., Aqueous Solutions of Paraffin Chain Salts, A Study in Micelle Formation, 1936..

  6. Drug-loaded micelle structure is generally synthesized using three main approaches: (1) Direct dissolution: This includes self-assembly of amphiphilic copolymer and drug in the solvent, but the main drawback of this method is low entrapment of drug in the particles. (2) Solvent evaporation technique: In this method the drug and the copolymers both are dissolved in a volatile solvent, and a thin film of self-assemble micelles is formed due to evaporation of the solvent. (3) Dialysis method for synthesizing micelles: Drug and the polymer are dissolved in an organic phase in a dialysis bag and then dialyzed against water. Micelles are used for targeted drug delivery due to their high drug loading capacity, and opsonization of these micelles with sugar or peptide can also result in receptor-mediated targeted drug or gene delivery. pH and temperature-sensitive copolymers are used to develop intelligent vehicles, which are currently being used for achieving controlled release (Mourya et al., 2011). Intermolecular interaction among the block polymers leads to the formation of micelles, which can be classified into the three following categories.
