This study used a thiolated calix[4]arene derivative modified on gold nanoparticles and screen-printed carbon electrode (TC4/AuNPs/SPCE) for Pb2+ Cu2+ determination. The surface of the was characterised via Fourier-transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), cyclic voltammetry (CV), electrochemical impedance (EIS). Differential pulse (DPV) detect...

Furaltadone (FLD) is an antibiotic drug that widely treated for coccidiosis, intestinal infection, and turkey blackhead. Moreover, excessive use of FLD may have some negative consequences humans domestic animals. Therefore, practical, sensitive, selective, facile detection still needed. In this exploration, a Eu2(WO4)3-nanoparticles-modified screen-printed carbon electrode was developed the low...

It has recently been demonstrated that 2-aminoacetophenone (2-AA) is a chemical indicator in exhaled air/breath of Pseudomonas aeruginosa infection associated with progressive life threatening decline of lung function in cystic fibrosis sufferers [Scott-Thomas et al., BMC Pulm. Med., 2010, 10, 56]. Currently the detection of 2-AA involves laboratory based instrumentation such as mass spectromet...
