Biochemical devices are tools that utilize biological materials to perform specific functions, often in the fields of medicine and environmental monitoring. These devices can include sensors that detect pathogens, glucose meters for diabetes management, and biosensors that monitor chemical changes in the body. They leverage the unique properties of biomolecules, such as proteins and nucleic acids, to achieve their tasks. These devices play a crucial role in diagnostics and therapeutic applications. For example, CRISPR technology is used in some biochemical devices for gene editing, while enzyme-based sensors can measure levels of various substances in the body. Overall, biochemical devices enhance our ability to understand and interact with biological systems.
