The field of nanotherapeutics is the application of nanotechnology to medicine and drug development.
Nanogels are composed of flexible hydrophilic polymers. A drug can be incorporated in the nanogel upon swelling in water. Incorporation of the drug results in the formation of solid dense nanoparticles. Nanogels allow the physical encapsulation of bioactive compounds such as DNADNA, proteins, carbohydrates and drugs. Nanogel preparations on the market include San Care Nanogel, ZyflexNanogel, Augen Nanogel Eye-care Gel, Skin Perfect Brightening Nanogel and Oxalgin.
