British scientists have used infrared spectroscopy to identify biochemical differences between endometrial tissue growing outside the uterus (ectopic) and the endometrial tissue of the uterus (eutopic). They also compared the results with tissue from endometriosis-free women (benign ...

A water-soluble zinc-based fluorescent sensor to detect pyrophosphate in blood has been developed by scientists from China. Pyrophosphate plays an important role in metabolic processes in the body but a lack of the compound can lead to Mönckeberg’s arteriosclerosis – calcium deposits in ...

The organochlorine 2,2-dichloropropionate, also known as dalapon, is a herbicide that’s regulated in potable water in Australia, but it is also a little known disinfection by-propduct (DBP). Typical levels when formed as a DBP and their relationship to other DBPs are virtually ...

A sensor that can discriminate between different tannins and be used to fingerprint a wide variety of red wines to confirm their authenticity has been developed. US scientists report in Chemical Science that they made the sensor with colour-changing indicators. They used it to test wine ...

A sensor to be injected into the skin just like a tattoo that measures sodium concentrations in the blood has been developed by US scientists. The sensor could be used to monitor diseases or warn against dangerously low sodium levels during exercise. Scientists report in Integrative Biology ...

Microfluidics can be used to trap a single DNA–enzyme complex in its native state, without immobilisation. These studies have usually been performed by immobilising either the enzyme or the DNA on a glass slide, but this may modify their properties, and make it difficult to analyse the ...

Fingerprints that have been washed off surfaces could now be retrieved thanks to a development by scientists in the UK and reported in the Journal of Materials Chemistry. The strained four-membered ring system, S2N2 quickly polymerises to (SN)x in the presence of fingerprints. This ...

Optical antennas made of gold nanoparticles can enhance the sensitivity of photoluminescence and vibrational spectroscopy, according to research published in Chemical Science. In traditional microscopy and spectroscopy, components such as lenses, mirrors and diffractive elements are used to ...

A new, fast way to analyse DNA could be used to sequence the genomes of viruses and in the future help tackle genetic disorders such as schizophrenia and congenital heart defects. Robert Neely and colleagues have used a DNA methyltransferase enzyme to label the 5’-GCGC-3’ DNA sequences with ...
