Photos of RGB and multispectral imaging laparoscopes

Multispectral imaging makes it possible to visualise certain functional properties of tissue that are invisible to conventional camera systems, such as the blood perfusion status of an organ.

The combination discerns healthy tissue from tumours based on their spectral profiles with higher accuracy than fluorescence-guided surgery alone.

A new paper has reviewed the combination of instrumentation and computational approaches to coherent Raman scattering.

ACD/Labs will combine their expertise in chemical information management with the knowledge and expertise of ELSIE consortium members to create a searchable knowledge repository of pre-competitive data.

Vibrational spectroscopy of substitutional Si impurities in graphene

Researchers have pushed the sensitivity of single-atom vibrational spectroscopy to the chemical-bonding-configuration extreme, which is critical for understanding the correlation of lattice vibrational properties with local atomic configurations in materials.

New calibration approach and new NPL reference materials will enable more widespread deployment of proton transfer reaction mass spectrometers (PTR-MS) for long-term atmospheric monitoring.

Chiral molecules

Researchers at the Fritz Haber Institute have integrated one of the new chiral optical methods with the study of gas-phase anions, which enable mass-selection and the use of a simple table-top laser for observation of the chiral effect.

The new technology integrates several important parts of the spectrometer into one device and is compatible with relatively large magnetic fields.

A brief schematic diagram of the detection principle and method

A new non-invasive screening method for T2D uses self-developed proton transfer reaction-mass spectrometry.

Acquisition will make electron capture dissociation (ECD) technology available to more biopharma researchers and labs globally.
