Bioaerogels: Synthesis approaches, cellular uptake, and the biomedical applications

Abstract

Aerogels are a class of porous structures with promising physicochemical properties. Among aerogels with various origins, polysaccharide aerogels (e.g., cellulose, chitosan, alginate, starch, agar, and so on) have received more attention. This group of aerogels can be classified as bioaerogels, which are originated from natural, semi-synthetic, and synthetic sources with exceptional biomedical applications. This review focuses on bioaerogels from the viewpoints of synthesis approaches, cellular uptake, toxicity, biodegradability, and the biomedical application perspectives.
