Modifications of polysaccharide-based biomaterials under structure-property relationship for biomedical applications

Applications of infrared spectroscopy in polysaccharide structural analysis: Progress, challenge and perspective

“…There are many different types of substitution groups in polysaccharide chains, naturally existed or chemically installed. Their existences are reported to have relation with bioactivities of polysaccharides ( Luo, Zhang, Wu, & Zhao, 2021 ). IR spectroscopy is a reliable analytical method used to confirm existences of different substitution groups in polysaccharides, due to its sensitivity, quick readout, and minimal sample requirement ( Caputo et al, 2019 ).…”

Nature-Based Biomaterials and Their Application in Biomedicine

“…The biomaterials include alginates, the structural cell wall constituent of many seaweeds [223], chitin and its derivative chitosan from crustacean and fungal sources [224], and cellulose, the most abundant polysaccharide on earth [225]. Many polysaccharides exhibit biocompatibility, stability and biodegradability, as well as widespread natural abundance, which lends them potential in biomaterials applications [226,227].…”

Evaluation of the fermentation of acetylated agave fructans (agavins), with Saccharomyces boulardii as a probiotic

“…In this regard, the use of chemical modifications in polysaccharides such as gums, pectins, starch and fructans, has been an alternative for used it wall material because they are chemically versatile due to their hydrophilic groups, which can generate non-covalent bonds and thus become more available. These polysaccharides also exhibit characteristics such as biodegradability (Mizrahy and Peer, 2012;Liu et al, 2015;Fertah et al, 2015;Luo et al, 2021). However, when these types of modifications are applied to polysaccharides with prebiotic capacity, their chemical structure can be affected.…”
