Raman boost: Low-cost solutions

Date: Jan 5, 2018

Author: David Bradley

Arranging nanoparticles on nanowires can enhance surface-enhanced Raman spectroscopy (SERS) by exploiting electromagnetic fields to boost scattering and thus sensitivity of standard dyes, such as R6G, by many times, according to researchers in India.

Journal Highlight: Coordinated EDX and micro-Raman analysis of presolar silicon carbide: A novel, nondestructive method to identify rare subgroup SiC

Date: Jan 1, 2018

Author: spectroscopyNOW

A novel method to nondestructively identify presolar SiC grains has employed backscattered electron-energy dispersive X-ray and micro-Raman analyses using high initial 26Al/27Al ratios and extreme 13C-enrichments.

Germanium-tin nanoparticles: Correlated with Raman spectroscopy

Date: Dec 1, 2017

Author: David Bradley

Raman and photoluminescence spectroscopies have been used to quantify lattice strain and photoluminescence behaviour in tin nanoparticles. The investigation reveals a correlation between the amount of tin in the nanoparticle core and how well the core's lattice matched that of its cadmium sulfide outer shell.

Journal Highlight: In vivo Raman spectroscopy–assisted early identification of potential second primary/recurrences in oral cancers: An exploratory study

Date: Nov 27, 2017

Author: spectroscopyNOW

Higher rates of local recurrences ascribable to field cancerization that occur with oral cancers have been explored by Raman spectroscopy, which can identify oral precancers, cancers, and field cancerization in humans and micro-sized mechanical irritation-induced tumors in animals.

Heart stopping science: Raman sensor

Date: Nov 1, 2017

Author: David Bradley

A new device that uses resonance Raman spectroscopy can determine whether the body's tissues are adequately oxygenated and if placed on the heart, predict cardiac arrest in critically ill patients.

Journal Highlight: Raman microspectroscopic mapping: A tool for identification of fused materials in fire debris

Date: Oct 2, 2017

Author: spectroscopyNOW

Raman microspectroscopy mapping has been demonstrated for material identification postfire in complex situations, such as the production of fused masses during fire dropdown, analysing a 10 μm × 10 μm square of the masses.
