Gelatin nanoparticles: a potential candidate for medical applications

Abstract

AbstractGelatin is a protein obtained from the hydrolysis of collagen. Gelatin is an attractive biodegradable material for use in nano-biotechnology and nano-pharmaceutics. Gelatin nanoparticles (NPs) have been widely used as drug and gene carrier to targeted sick tissues including cancer, tuberculosis, HIV infection along with the treatment of vasospasm and restenosis, due to its biocompatibility and biodegradability. For instance, coating with gelatin lowers the cytotoxicity of quantum dots. Moreover, gelatin NPs have the ability to cross the blood-brain barrier, hence proven as a promising candidate to target brain disorders. Macrophage targeting with gelatin NPs for remedy of different diseases is repeatedly reported in previous years. In tissue engineering gelatin is actively utilized for construction of biological and life-long 3D scaffolds for bio-artificial tissues and organ production. Gelatins have a wide range of potential applications which needs to be unraveled in more detail. This review is mainly focused on the applications of gelatin NPs in biomedical sciences.
