Advancements in biopolymer-metallic nanocomposites have led to diverse applications, including drug delivery, biosensing, bone regeneration, solar cells, and supercapacitors. This development supports sustainable progress through a biomimetic approach where the integration of metallic nanoparticles plays a crucial role. This paper reviews how functionalizing metallic nanoparticles using various methods can prevent agglomeration and enhance the thermal, mechanical, and electrical properties of biopolymers. It details the improvements in properties and potential applications achieved by the incorporation of metal-based nanofillers into biodegradable biopolymers. The benefits of metallic nanoparticles such as their high aspect ratio, biocompatibility, low density, and high mechanical strength are highlighted as key factors in boosting biopolymer performance. The review summarizes the mechanism and structural changes in biopolymers to provide researchers with insights into these elements.
