A highly selective fluorescent sensor for naproxen utilizes carbon dots as the fluorophore and molecularly imprinted polymer to provide the recognition sites. The fluorescence of carbon dots can be selectively quenched by naproxen.
A fluorescent sensor with recognition ability for norepinephrine was simply prepared and actually used to determine norepinephrine in rat plasma.
The novel MIPs-coated UCNPs fluorescent sensor could be used for on-field detection of diethylstilbestrol in real samples.
