Recent development in polymeric nanohydrogel demands surface modification, interfacial properties and determination of molecular weight for effective drug loading and release studies. Therefore, chitosan built nanohydrogel were synthesized via free radical copolymerization and functionalized with hydrophilic ligands to act as amphiphilic diblock copolymers in aqueous medium. The investigated properties like porosity (61- 73 %) , cross-linking density (20.38- 25.22), critical micelle concentration (CMC≈ 0.41- 0.62 g/L), thermodynamic of adsorption followed by micellization, and the molecular weight of chitosan built nanohydrogel (Mw ≈11.59- 13.05 x 105 (g/mol, determined by applying Debye plot) have been investigated as a new tool to understand the art and chemical identity of hydrogel at air- water interface in aqueous medium regarding controlled drug delivery applications.

This study presents the design of novel composites nanogels, based on poly(ethylene glycol) diacrylate and natural zeolite particles, that are able to act as materials with controlled drug delivery properties. Natural zeolite–nanogels composite, with varying zeolite contents, were obtained by an inverse mini-emulsion technique and loaded with 5-fluorouracil, a widely used chemotherapeutic drug. Herein, the possibility of adjusting final properties by means of modifying the preparation conditions was investigated. The prepared composite nanogels are characterized by dynamic light scattering (DLS), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). In light of this tunable drug-loading capability, swelling behaviour, and cytotoxicity, these composite nanogels could be highly attractive as drug reservoirs.

Reversed lipid liquid crystalline nanoparticles (LCNPs) of the cubic micellar (I2) phase have high potential in drug delivery applications due to their ability to encapsulate both hydrophobic and hydrophilic drug molecules.
