Progress in Rigid Polysaccharides-Based Nanocomposites with Therapeutic Functions

Abstract

Polysaccharides are naturally occurring biological macromolecules that are envisaged as promising substitutes of non-degradable polymers due to their outstanding inherent properties of biodegradability, biocompatibility, low cost and availability. Their utilization in the development of nanostructured hybrid materials has numerous advantages in theranostics, the integrated approach of therapeutics and diagnostics. In particular, some rigid polysaccharides occur in nature, which can self-assemble into ordered hierarchical structure, facilitating the controllable fabrication of various nanocomposites. These rigid polysaccharides, including Lentinan, Curdlan, Schizophyllan, Scleroglucan, Auricularian and yeast glucan, possess the linear β-(1→3)-D-glucan as the backbone with or without β-(1→6)-linked glucose as the branch, having diverse biological activities. Hence, this review not only focuses on the incorporation of nanoparticles such as gold (AuNPs), silver (AgNPs), selenium (SeNPs), silica, carbon nanotubes, homo-polynucleotides, bio-imaging probes and drugs into different rigid polysaccharide matrixes through self-assembly, but also summarizes their biological functions as well as the correlation to their conformations. Additionally, the as-engineered polysaccharide nanocomposites as effective therapeutic agents, and the challenges or ambiguity issues concerning further practical clinic therapeutic were also addressed.therapeutics and diagnostics.
