Smartphone-based colorimetric determination of gamma-butyrolactone and gamma hydroxybutyrate in alcoholic beverage samples (2023)
Presentation / Conference
Honeychurch, K. (2023, March). Smartphone-based colorimetric determination of gamma-butyrolactone and gamma hydroxybutyrate in alcoholic beverage samples. Presented at FCN Drugs and Toxicology Meeting, Online (Microsoft Teams)

amma-hydroxybutyrate (GBH) is a popular recreational drug. Its strong sedative and amnesic effects have led to drug-facilitated sexual assaults, poisonings, overdose, and death. As a result, legislation has restricted its availability leading to GHB,...
