A recent study by researchers from the University of Belgrade highlights the transformative potential of attenuated total reflectance Fourier transform infrared (ATR-FT-IR) spectroscopy for analyzing protein structures. This versatile method not only provides insights into secondary structures but also excels at tracking aggregation processes, offering advantages over traditional techniques like X-ray crystallography and nuclear magnetic resonance (NMR) spectroscopy.

A new model corrects errors in analyzing complex mixtures using ATR FT-IR, paving the way for more accurate chemical insights.

Scientists have developed a novel and creative mid-infrared (MIR) hyperspectral microscope using single-pixel imaging (SPI) technology and a quantum cascade laser (QCL). This innovation offers faster, more cost-effective chemical analysis compared to traditional methods, promising new frontiers in microscopic imaging.

Despite its widespread adoption in food quality analysis, near-infrared (NIR) spectroscopy lags behind in regulatory recognition. A study led by researchers from Italy and Spain highlights the disparity between its scientific applications and official methods, urging standardized regulations to fully leverage NIR's sustainability benefits.

Researchers from the University of Cordoba have validated a novel spectroscopy technique to help distinguish between extra virgin and virgin olive oils. This approach could support existing panel-based tests, which are often slow, costly, and subjective, by providing a faster, non-destructive screening option.

Recent research highlights the potential of infrared (IR) spectroscopy as a noninvasive diagnostic tool for cancer detection through blood derivatives. However, significant confounding factors pose challenges to its clinical adoption, necessitating rigorous standard operating procedures.
