D'Auria et al., Anal. Methods, 2012, Advance Article

Researchers in Italy have developed a new technique for detecting an amphetamine and methamphetamine precursor, 1-phenyl-2-propanone, also known as benzyl methyl ketone (BMK). Catching the precursors in shipment reduces the manufacturing and availability of these dangerous drugs, but it can be difficult as the density is similar to water. Common techniques such as gas chromatography and HPLC, while effective, require large instrumentation with testing performed in the laboratory. Alternatively, Stefano Di Giovanni, Sabato D’Auria and coworkers synthesized a BMK derivative, with the goal of growing antibodies and detecting the resulting fluorescent signal from binding with BMK. Using this system, they have managed to detect down to 100 nM and, are transitioning from large laboratory equipment towards a smaller, portable optical detection device. This article will be free to read until Oct 19th.

Researchers from Central South University, Changsha, Hunan and Anyang Normal University, Anyang, Henan, China report a simple, rapid and selective colorimetric visualization of arsenic using unmodified gold nanoparticles (AuNPs) and a phytochelatin-like peptide.

The detection limit shown is 20 nM, which is lower than the World Health Organization’s (WHO) standard for drinking water, and the authors have demonstrated feasibility for the detection of arsenic in groundwater.

They say their method will be valuable for the design of new types of metal ions sensors and will likely lead to many colorimetric detection applications in environmental monitoring.
