Journal Highlight: Rapid detection of melamine in tap water and milk using conjugated "one-step" molecularly imprinted polymers-SERS sensor

Date: Jun 3, 2016

Author: spectroscopyNOW

An innovative sensor conjugating molecularly imprinted polymers and surface enhanced Raman spectroscopic-active substrate (MIPs-SERS) for the simultaneous extraction and determination of melamine from tap water and milk gave low LOD and LOQ.

Journal Highlight: Estimation of spectra sample size for characterizing single cells using micro-Raman spectroscopy

Date: May 2, 2016

Author: spectroscopyNOW

A study of the effects of sample size on the ability to generate single-cell Raman spectra that accurately describe the total molecular content of the cell demonstrates the importance of adequate spectral sampling.

Journal Highlight: Raman and SEM-EDX analyses of the "Royal Portal" of Bordeaux Cathedral for the virtual restitution of the statuary polychromy

Date: Mar 8, 2016

Author: spectroscopyNOW

Chemical analysis of the remains of paint from the Royal Portal of Bordeaux Cathedral has been carried out to provide a virtual estimate of the colouring when it was built in the XIII century.

Mummy art: Micro-Raman finds artist

Date: Mar 1, 2016

Author: David Bradley

Scientists in the USA have used micro-Raman spectroscopy and other techniques to take a close look at threelifelike portraits of mummy faces from 2000 years ago that suggest they are by the same artist.
