A recent study demonstrates the potential of infrared (IR) spectroscopy-based breath analysis as a non-invasive method to detect prostate cancer by identifying disease-specific volatile organic compounds.

This study uses Fourier transform infrared (FT-IR) spectroscopy to analyze how the globular protein ovalbumin's secondary structures transition under varying pH conditions in the presence of the cosolvent xylitol, highlighting the role of noncovalent interactions in these conformational changes.

Researchers from India developed a new micro-Raman spectroscopy system to detect and analyze microplastics.

Microplastics (MPs) and nanoplastics (NPs) are emerging contaminants requiring robust analytical techniques for identification and quantification in diverse environmental and biological matrices. This review highlights various spectroscopy methods, such as Raman, FT-IR, NIR, ICP-MS, Fluorescence, X-ray, and NMR detailing their methodologies, sample handling, and applications for characterizing MPs and NPs.
