What are MEMS?
Microelectromechanical systems (MEMS) are sophisticated devices that integrate mechanical elements, sensors, actuators, and electronics on a common silicon substrate. These tiny systems, often only a few micrometers in size, can perform a variety of functions, making them invaluable in numerous fields, including
toxicology.
Role of MEMS in Toxicology
MEMS technology has revolutionized the field of toxicology by enabling the development of highly sensitive and specific detection methods. These advanced systems can detect
toxins and
chemical agents at very low concentrations, which is crucial for early detection and prevention of toxic exposure.
Applications of MEMS in Toxicology
