Abstract

The effect of a polybenzimidazolium anion exchange polymer on improving sensitivity and selectivity toward the electrochemical detection of Δ⁹-tetrahydrocannabinol (Δ⁹-THC) has been investigated. Herein we report a rapid, inexpensive and stable approach to detecting 10–1000 ng mL⁻¹ of Δ⁹-THC in buffered solutions and in human saliva.
