This review addresses current and future perspectives of nanogel technology for nanomedicine. The synthetic methodologies and material properties of nanogels prepared by chemical meanings are discussed in detail, and examples that illustrate the different methodologies are presented. Applications in the fields of drug and gene delivery, smart imaging modalities, responsive materials, and multivalency as a therapeutic approach highlight the enormous potential of the functional nanogels as novel polymeric platforms for biomedicine.

Improved skin penetration of thermoresponsive nanogels into human skin at temperatures above the phase-transition temperature.

Crosslinked casein micelles with a dual pH and protease drug triggered release can be applied as a promising hydrophobic drug carrier material.

The synthesis, characterization and properties of pH/thermosensitive hydrogels based on acrylic acid (AAc) and N-isopropylacrylamide (NIPA) using (+)-N,N'-diallyltartramide (DAT) as cross-linking agent and water as solvent, are presented in this article. Subsequently, the incorporation of ofloxacin (OFL) as model drug to evaluate the drug load capacity of hydrogels and the in vitro release from OFL-polymer conjugate are presented in order to define potential pharmaceutical applications. Interestingly, the incorporation of AAc diversified the properties of NIPA-based hydrogels allowing ionic interaction of these new materials with drugs of opposite charge and produced different release profiles at pH 1.2 and 6.8 simulated physiological media.
