The excessive reliance on petroleum chemicals in the manufacture of polymers is one of the main issues with economic and environmental sustainability. With an emphasis on medical and environmental issues, this article provides an overview of the current state of knowledge on the characteristics, compounding techniques, and uses of biopolymers paired with biosensors. Consequently, this article is focused on polymer materials that are ecologically beneficial. The paper provides a summary of the current state of knowledge about the characteristics, compounding techniques, and uses of biopolymers mixed with biosensors, with an emphasis on medical and environmental issues. The study discusses both potential and the existing level of knowledge. The article demonstrates the widespread interest in biopolymers created from renewable basic resources in both research and business. These materials provide unique combinations of characteristics for brand-new applications in addition to replacing conventional polymers in numerous applications. Because biopolymer-based composite materials may decay when exposed to environmental variables, they are thought to be preferable to conventional nonbiodegradable materials. The research emphasises the use of polymers and nanomaterials in the manufacture of chemical sensors, which, owing to their biocompatibility and sensitivity, enable their use in environmental or medicinal applications. The analysis of current research in the area of biopolymer-sensor composites is the main goal of this study.
