Various types of fluorescent nanoparticles have been proposed for the detection of
veterinary drug residues in food. However, structure-induced fluorescence nanoparticles …

Residues of sulfadimethoxine (SDM) in animal-derived foods have attracted widespread
public concern. Herein, we propose an aptamer-based colorimetric/SERS dual-mode …

Self-assembled Eu-dipeptide (tryptophan-phenylalanine) microparticles with multi-emission
fluorescence was prepared and modified with a single-stranded DNA corresponding to the …

Quickly and sensitively detection of antibiotic residues in animal products often requires time-
consuming techniques and expensive instrumentation. To address these limitations, a high …

A polymer-based aptasensor, which consisted of fluorescein amidite (FAM)-modified
aptamers and coordination polymer nanobelts (CPNBs), was developed utilizing the …

Fluorescence-based aptasensors possess high sensitivity but are complicated and usually
require multistep labeling and modification in method design, which severely limit the …

A practical aptaprobe for sulfadimethoxine (SDM) detection was established. Based on the
electrostatic reaction, a duplex of aptamer and poly (diallyldimethylammonium …

Sulfadiazine (SDZ) residues in food products and the environment pose a serious threat to
human health and ecological balance, thereby warranting the development of new methods …

A dichromatic label-free aptasensor was described for sulfadimethoxine (SDM) detection.
Compared with the binding of SDM-aptamer to SDM, the higher affinity of aptamer to cDNA …

Sulfamethazine (SMZ) as a broad antibiotic is widely used in livestock and poultry. However,
the abuse of SMZ in livestock feed can lead to SMZ residues in food and the resistance of …
