Abstract

Nanostructured biopolymers represent a cutting-edge development in material science, combining the sustainability of biopolymers with the advanced properties of nanotechnology. These materials are engineered at the nanoscale to enhance the functional properties of biopolymers, such as mechanical strength, biodegradability, and bioactivity. By incorporating nanoparticles, such as nanocellulose, nanoclays, or metal nanoparticles, nanostructured biopolymers exhibit improved characteristics that make them suitable for a wide range of applications, including packaging, biomedical devices, drug delivery systems, and food preservation. The unique interactions between the nanostructures and biopolymers open new opportunities for developing high-performance, eco-friendly materials. This paper explores the preparation methods, functionalization techniques, and applications of nanostructured biopolymers, highlighting their potential in sustainable technology and industry innovation.
