biosensing techniques

Biosensing techniques are methods used to detect and measure biological molecules or signals, such as proteins, DNA, or hormones, for medical, environmental, or food safety applications. They typically involve a sensor that recognizes a specific substance and converts this recognition into a measurable signal, like an electrical current, color change, or light emission. These techniques enable rapid, accurate detection of biological information, aiding in diagnostics, monitoring health, or analyzing samples. Advances in biosensing focus on improving sensitivity, speed, and portability to make testing more accessible and reliable.
