Selective detection is a research area that focuses on developing methods and techniques to selectively detect specific target molecules or substances in a sample. This can involve designing sensors, detectors, or analytical methods that have high specificity and sensitivity for the target of interest, while minimizing interference from other components in the sample. Selective detection is important in various fields such as environmental monitoring, biomedical diagnostics, and food safety testing, where accurate and reliable detection of specific analytes is critical for decision-making and problem-solving. Researchers in this area often explore new materials, technologies, and strategies to improve the selectivity and performance of detection methods.
