Break­through in drug de­tec­tion

China Daily (Hong Kong) - - WORLD -

Re­searchers have code­vel­oped a sen­sor that is able to de­tect a per­son’s drug in­take with a drop of sweat, saliva or urine. Right now, drug test­ing in­volves us­ing com­plex di­ag­nos­tic de­vices that are of­ten bulky, ex­pen­sive and slow. The newly de­vel­oped portable sen­sor — sized at 1.5 x 3.5 cen­time­ters — is 10,000 times as ac­cu­rate as ex­ist­ing portable drugscreen­ing de­vices. If com­mer­cial­ized, the team said the tech­nol­ogy will make drug screen­ing as easy as test­ing for al­co­hol in­take with a breath­a­lyzer.
