Biosensing is a research area that focuses on developing sensors and technologies to detect biological molecules, cells, or organisms. These sensors are often used in medical diagnostics, environmental monitoring, and food safety. Biosensors can detect specific biomolecules, such as proteins, DNA, or viruses, and provide real-time, accurate measurements. Researchers in biosensing work on developing new materials, technologies, and methods to improve the sensitivity, specificity, and reliability of biosensors for various applications.
