scent detection

Scent detection involves trained individuals or animals, like dogs, identifying specific odors amidst complex smells. These detectors use their keen sense of smell to find particular substances—such as drugs, explosives, or even medical conditions—by recognizing unique scent signatures. Through specialized training, they learn to focus on target odors and ignore distractions, making scent detection a highly sensitive and reliable method for locating hidden items or conditions in various fields, including security, healthcare, and search-and-rescue operations.
