Application of Plant Polysaccharide Nanoparticles as Polymeric Carrier Materials for the Construction of Medicine Carriers

Nanoparticle-based drug delivery systems have become a favourable platform for target specificity in disease treatment, although their side effects and toxicity remain controversial. Plant polysaccharide nanoparticles are safe, natural biomaterials that have become candidate materials for nano-drug delivery systems due to their excellent biodegradability and biocompatibility. In addition to becoming candidate materials, plant polysaccharide nanoparticles show excellent pharmacokinetic and drug delivery characteristics as carrier materials to manipulate small drug molecules at the nanoscale, mainly improving medicine solubility, reducing medicine toxicity and side effects and enhancing biological targeting of medicines. Therefore, the application of plant polysaccharide nanoparticles in the field of drug delivery systems may become the focus of future studies. Here we review the carrier function of plant polysaccharide nanoparticles as a polymeric material in drug delivery. The limitations and challenges of applying plant polysaccharide nanoparticles in drug carrier systems are highlighted with the aim to provide a reference for their precise development.
