Colorimetric paper sensor for visual detection of date-rape drug γ-hydroxybutyric acid (GHB)

Electrospun Nanofibrous Membrane-Based Colorimetric Device for Rapid and Simple Screening of Amphetamine-Type Stimulants in Drinks

“…In various drinks, including alcoholic drinks, the color change of the DSKs provided a visual indication of the presence of ATSs. These DSKs can aid in preventing the unintentional intake of drugs and provide proactive protection against drug-facilitated crimes …”

Conductive Thread-Based Immunosensor for Pandemic Influenza A (H1N1) Virus Detection

“…The miniaturization of various biosensors is also under active investigation. These include portable fluorometer-based biosensors for on-site disease detection, , colorimetric sensors to detect infectious pathogens by color change, − and smartphone-based biosensors for point-of-care detection of infectious disease. − Efforts are also underway to develop a user-friendly biosensor that can detect bioaerosols in the user’s surroundings in real-time . In this study, we developed a conductive thread-based immunosensor (CT-IS) for the detection of pH1N1 virus, which is one of the viruses transmitted via bioaerosols.…”
