Highly sensitive and selective detection of naproxen via molecularly imprinted carbon dots as a fluorescent sensor.

ABSTRACT: The overuse and inappropriate discharge of naproxen, a common anti-inflammatory medication and an emerging contaminant in water, is detrimental to human health and bodies of water. Here, we design a fluorescent sensor based on molecularly imprinted carbon dots (CDs) for highly selective detection of trace amounts of naproxen. The CDs were encapsulated into the pores of silica through a sol-gel based method and provide fluorescent signal. After removal of the template molecules, a molecularly imprinted polymer layer was formed and the fluorescence of the CDs sensor was selectively quenched by naproxen. A detection limit of as low as 0.03 μM and a linear range of 0.05-4 μM for detecting naproxen in aqueous solution were obtained. High recoveries of naproxen levels in waste water and urine sa
