Red emissive N-doped carbon dots encapsulated within molecularly imprinted polymers for optosensing of pyrraline in fatty foods

Chenchen Xie et al.

Summary: A novel and facile method for preparing red emissive N-doped carbon dots encapsulated in molecularly imprinted polymers (RNCDs@MIPs) was proposed using a one-pot room-temperature reverse microemulsion polymerization. RNCDs were synthesized using citric acid and urea as carbon and nitrogen sources through solvothermal synthesis, with an optimum emission wavelength of 620 nm. The unique optical properties of RNCDs combined with highly selective MIPs allow the RNCDs@MIPs conjugate to adsorb specific targets of pyrraline (PRL), leading to fluorescence quenching of the RNCDs. The optosensing probe demonstrated good reproducibility and was successfully used for the detection of PRL in fatty foods, with spiked recoveries ranging from 85.93% to 106.96%.

Khadija Karim et al.

Summary: A competitive assay based on molecularly imprinted polymer (MIP) was developed for the rapid screening of acetazolamide (ACZ) using a colorimetric method coupled with smartphone-based detection.
