| Aerogels are a class of porous structures with promising physicochemical properties. Among aerogels with variousorigins, polysaccharide aerogels (e.g.,cellulose, chitosan,alginate, starch,agar,andsoon)havereceived more attention. This group of aerogels can be classified as bioaerogels, which are originated from natural, semisynthetic, 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. |
