Overview of Protein‐Based Biopolymers for Biomedical Application

Abstract

Biopolymers are playing a vital role in biomedical applications. Among them, protein‐based biopolymers are utilized for the fabrication of tissue‐engineering constructs, therapeutic molecule delivery carriers, emulsifiers, and food packaging materials. Wide ranges of proteins are extracted from animal or plant sources and are being utilized for the fabrication of scaffolds for regenerative tissue‐engineering application. Here, an overview about the protein structure, extraction procedure, solubility, and various formulation‐based proteins found in the literature are discussed. Biopolymers display several advantages such as biocompatibility and degradability by enzymes. Methods to overcome the disadvantages of these proteins such as immunogenicity, antigenicity, and solubility are reported. Various crosslinking reagents specific to protein chemistry are discussed as well.

Insights on Health and Food Applications of Equus asinus (Donkey) Milk Bioactive Proteins and Peptides—An Overview

“…Furthermore, it is well known that there is a strong qualitative resemblance between the principal classes of proteins (i.e., caseins and whey proteins) in all types of milk. These whey proteins and caseins could have biomedical applications [ 8 , 9 ]. Due to its high nutritional and health importance, DM is rediscovered as a functional food.…”

“…Gelatin has the advantages of gel-forming, thickening, and emulsifying characteristics with favorable biocompatibility, mechanical properties, and biodegradation in normal healing time of 6 to 8 weeks 27 , 28 . Gelfoam is one of the most commonly used absorbable gelatin sponges for enhancing the healing of extraction wounds with favorable biocompatibility and cost-effectiveness.…”

New Developments in Medical Applications of Hybrid Hydrogels Containing Natural Polymers

“…Cationic or anionic charged gelatin is usefful for loading therapeutic principles (molecules, drugs) through electrostatic interactions. In contrast with collagen, gelatin manifests good stability at high temperature in a broad interval of pH [313]. Synthetic polymers such as PEG and PVA are some of the most used for the obtaining of hybrid gelatin based hydrogels with application in almost all the medical domains.…”
