How does a Biochip work?

A biochip is a miniaturized device that integrates biological elements, such as DNA, proteins, or cells, with microelectronics to perform analyses and diagnostics. It works by capturing biological samples, which then interact with the immobilized biomolecules on the chip's surface. These interactions generate signals, such as fluorescence or electrical changes, that can be measured and analyzed to provide insights into biological processes or detect diseases. Biochips are commonly used in applications like genetic testing, drug discovery, and disease diagnostics.
