Detecting Al³⁺ with the naked eye

Aluminium has many widespread applications including, packaging materials, food additives, clinical drugs, water purification, building construction etc. Too much Al can cause damage to the central nervous system, and is believed to have a role in neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease. Debasis Das and colleagues from The University of Burdwan, India, have developed a highly sensitive fluorescent probe that can detect Al³⁺, with a green glow that can be seen by the naked eye.

This HOT article from Xiaojing Chen and co-workers of Wenzhou University, Zhejiang Province, China, looks at the analysis of enantiomeric excess. The enantiomeric forms of many compounds exert different physiological and therapeutic effects, which are an important consideration in pharmaceutical and agrochemical research, leading to large and increasing demands for single-enantiomer products.

Many existing approaches can be time-consuming and destructive, but NMR has wide applicability due to its high speed, reliable detection for quantitative and qualitative analysis. The drawback, however, is the need for an equivalent or excess amount of the chiral reagent required to give rise to signal splitting, and these reagents are usually expensive or difficult to obtain.

Here, the authors selected quinine, a commercially available and inexpensive reagent, as a chiral shift reagent to induce discrimination in the NMR spectra of enantio-isomers. They say their findings provide an accurate, rapid, and inexpensive method of determining the enantiomeric purity of amino acid derivatives, and show great potential in both peptide and pharmaceutical syntheses.

Zhu et al., Anal. Methods, 2012, Advance Article

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

From Italy, we have a team of scientists that have developed a biochip device that can detect ephedrine. Sabato D’Auria from the Laboratory for Molecular Sensing, IBP-CNR, and colleagues designed the chip to combine an immunochemical method with surface plasmon resonance spectroscopy to detect ephedrine at levels as low as 33 ng per mL. Ephedrine is a chemical precursor used to illegally produce amphetamines and therefore a quick and easy method to detect it is important.
