Colon cancer calculated: Metabolic profiling

Date: Aug 15, 2013

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy can be used to obtain a metabolic fingerprint of cancer of the bowel and so determine how far advanced the disease is, according to UK researchers.

Journal Highlight: 3He NMR: from free gas to its encapsulation in fullerene

Date: Aug 5, 2013

Author: spectroscopyNOW

The 3He nuclear magnetic shieldings were calculated for single helium atom, its dimer, simple models of fullerene cages (He@Cn), and single wall carbon nanotubes.

Plague detector: Sweet solution

Date: Aug 1, 2013

Author: David Bradley

Anti-carbohydrate antibodies can be used to identify the presence of the pathogen that causes the deadly disease we know as plague, Yersinia pestis.

Magnetic insights: Playing the percentages

Date: Jul 15, 2013

Author: David Bradley

An international research team has shown that one-dimensional molecular conducting wires can be switched to an insulating state using a weak magnetic field even at room temperature. The finding might offer new insights into the innate navigation systems of migratory birds as well as leading to new technology for magnetic field sensors, inexpensive touch screen displays and high-density magnetic storage for smartphones and other portable devices.

Journal Highlight: Does aluminium bind to histidine? An NMR investigation of amyloid β12 and amyloid β16 fragments

Date: Jul 2, 2013

Author: spectroscopyNOW

In an NMR study of the N-terminal amyloid peptide fragments Aβ12 and (Aβ16), non-histidine residues were found to be involved in aluminium binding.

Liquid study: Reveals tuneable colours

Date: Jul 1, 2013

Author: David Bradley

Researchers in Japan have used NMR spectroscopy to study liquid materials with excellent light stability based on the skeleton of the organic fluorescent dye anthracene that could be used for full-colour tuneable luminescent systems.

Invisible touch: What's the matter?

Date: Jun 15, 2013

Author: David Bradley

An explanation as to why we cannot detect 85 percent of the predicted mass of the universe has emerged from fundamental particle research carried out in the 1930s. US physicists have now proposed that dark matter, may be composed of Majorana fermions, which are anapoles with a doughnut-shaped electromagnetic field invisible to any known detector technology.

Journal Highlight: Assessment of higher order structure comparability in therapeutic proteins using nuclear magnetic resonance spectroscopy

Date: Jun 3, 2013

Author: spectroscopyNOW

NMR spectroscopy using a fingerprinting approach has been used to rapidly assess higher order structure comparability in three nonglycosylated proteins spanning a molecular weight range of 6.5–67 kDa.

Handheld cancer detection: Microfluidics meets NMR

Date: Jun 1, 2013

Author: David Bradley

A handheld device first developed for cancer diagnosis has been adapted to rapidly diagnose tuberculosis (TB) and other bacterial infections. Two papers appearing in the journals Nature Communications and Nature Nanotechnology describe the portable systems that bring together microfluidics technology and NMR.

Combined effort: Spectroscopic cancer clues under the microscope

Date: May 15, 2013

Author: David Bradley

A combination of atomic force microscopy (AFM) and nuclear magnetic resonance (NMR) spectroscopy could provide oncologists and cancer researchers with a new way to probe how cancer cells spread in the body through metastasis as well as other disease-related processes.
