Area of Science:

• Biomaterials Science
• Nanotechnology
• Chemical Synthesis

Background:

• Polysaccharide-based gold nanomaterials (Au NMs) show promise in biomedicine due to extended in vivo presence and immune system stimulation.
• Their applications span cancer therapy and immunomodulation, driving research into their synthesis and properties.

Purpose of the Study:

• To comprehensively review the synthesis mechanisms of polysaccharide-based Au NMs.
• To explore the influence of polysaccharide structure and reaction conditions on Au NM characteristics.
• To summarize the current applications of these nanomaterials in cancer therapy.

Main Methods:

• Review of synthesis mechanisms including glycosidic bond cleavage, hydroxyl group reduction, and amino group reduction.
• Analysis of polysaccharide structural factors (molecular weight, monosaccharide composition, functional groups, glycosidic bonds, chain conformation).
• Investigation of reaction condition effects (temperature, time, pH, precursor concentrations).

Main Results:

• Detailed classification of synthesis pathways based on polysaccharide type and reaction environment.
• Demonstrated correlation between polysaccharide structure/reaction conditions and Au NM size/shape.
• Overview of current research on the anticancer activity of polysaccharide-based Au NMs.

Conclusions:

• Polysaccharide-based Au NMs represent a versatile platform for advanced biomedical applications.
• Understanding synthesis-structure-property relationships is key to optimizing their therapeutic potential.
• Further research is needed to fully elucidate their anticancer mechanisms and clinical efficacy.
