biological detection

Biological detection involves using living organisms, such as bacteria, plants, or animals, or biological materials to identify the presence of specific substances, pathogens, or environmental conditions. These biological systems can recognize and respond to particular signals or contaminants, producing measurable responses like color changes, electrical signals, or other detectable outputs. This method provides sensitive, specific, and often rapid detection, useful in medical diagnostics, environmental monitoring, food safety, and biodefense. Essentially, biological detection leverages natural biological processes or responses to identify target substances accurately and efficiently.
