Abstract: Abstract We report a label-free liquid crystal (LC)-based biosensor for sensitive detection of arsenic (III) ions (As3+) in aqueous solutions, using an arsenic-binding aptamer (Ars-3 aptamer) as a molecular recognition element. In this sensing system,… read more here.

Abstract: A luminescent nanoprobe (NP), MnO2-modified Er3+/Yb3+-codoped Ag2MoO4 upconversion nanoparticles (UCNPs; cod-AMO-3/MnO2), was constructed for rapid, sensitive, and selective "turn-on" detection of trace As3+. Herein, two kinds of luminescent NPs were developed based on luminescence resonance… read more here.
