The document discusses biosensors and bioplastics. It defines a biosensor as a device that combines a biological component with a physical sensor to detect analytes. The first biosensor was invented in 1950. It describes several types of biosensors including electrochemical, physical, calorimetric, amperometric, and optical biosensors. Bioplastics are defined as biodegradable plastics derived from renewable sources that can reduce plastic waste. The first bioplastic was discovered in 1926. Common sources of bioplastics include corn, potatoes and soybeans. Types include starch-based, cellulose-based and protein-based bioplastics. The document outlines several applications and advantages of biosensors and bioplastics
