Answer
The concept of biosensors was pioneered in the 1960s, with the first practical biosensor being developed by Updike and Hicks in 1967 for glucose detection. This innovation marked a significant milestone in analytical chemistry, leading to the proliferation of various biosensor technologies that have since been applied in diverse fields, including healthcare, environmental science, and food safety. The evolution of biosensors has continued, with ongoing research leading to more sophisticated and sensitive devices.
