It is not a simple task to develop techniques for analyzing tricyclic quaternary ammonium
alkaloids (TCQAAs) because of the relative polarity and alkalinity of the latter. Moreover, less …

Background The widespread use and abuse of antibiotics has resulted in the pollution of
water sources with antibiotic residues, posing a threat to human health, the environment …

Target specificity, one of aptamer characteristics that determine recognition efficiency of
biosensors, is generally considered to be an intrinsic property of aptamer. However, a high …

In this research, a novel electrochemical sensor with excellent sensitivity was fabricated
based on Cu quantum dot (Cu QD) and SH-SiO 2 nanoparticles immobilized on copper …

Abstract Iron-copper nanozymes (Fe-Cu NZs) with good peroxidase activity were prepared
through hydrothermal method by using copper nitrate as copper source, iron acetate as iron …
