Abstract
Recent technological advances in the field of biomaterials and tissue engineering have spurred the interest in biopolymers for various biomedical applications. The advantage of biopolymers is their favorable characteristics for these applications, among which proteins are of particular importance. Proteins are explored widely for 3D bioprinting and tissue engineering applications, wound healing, drug delivery systems, implants etc. and the proteins mainly available include collagen, gelatin, albumin, zein, etc. Zein is a plant protein abundantly present in corn endosperm and it is about 80% of total corn protein. It is a highly renewable source and zein has been reported to be applicable in different industrial applications and of late it is gaining attention in biomedical applications. This research interest on zein is on account of its biocompatibility, non-toxicity and also its certain unique physico-chemical properties. Zein comes under GRAS category and is considered safe for biomedical applications. The hydrophobic nature of this protein imparts it an added advantage and has wider applications in drug delivery. This review focuses on details about zein protein, its properties and potential applications in biomedical sectors.
