An assistant professor of chemistry is developing a tiny testing kit that women can carry in their purses and use to quickly detect date-rape(3) drugs.
Andrea Holmes, who teaches at Doane College in Crete, said many women on college campuses were being affected by this.
Date-rape drugs such as Rohypnol(4) are secreted(5) into a person's drink. The drug incapacitates the person and causes memory loss. Men and women who have been raped while under its influence can regain their senses with no memory of the assault.
“约会强暴”药物 – 例如“迷奸药”- 会被偷偷地下到人们的饮料中。这种药物使人浑身无力并且导致记忆丧失。在这种药物作用下被强暴的男女事后能恢复意识却无法记起被袭过程。
Holmes said what they wanted to do was to determine the presence of the drug before it ever entered the body.
She's hoping to develop a small strip or stick that would turn a certain color if dipped(6) into a drink that had been spiked(7) with roofies.
In May, she and three student researchers reached a milestone: They concocted(8) a chemical mixture that turns from blue to colorless when Rohypnol is added.
Holmes said it took them weeks and weeks before making the breakthrough(9).
Other researchers have made progress on similar ideas.
The Drink Detective was introduced in Britain in 2004. A few drops of a detection liquid are placed on a pad that has been dipped into a drink. The pad changes colors if roofies were put into the drink.
Holmes wants something even smaller and simpler: a paper sensor (10) that can fit into a pocket or small handbag.
"It is a big, big area of research," she said. "Everybody is trying to create their own sensor."
