There is lack of a worldwide standard technique for clinical diagnosis of interstitial cystitis (IC). Raman spectroscopy with higher specificity and sensitivity has been extensively used to act as a non-destructive analytical technique without special sample preparation. In this preliminary study, possible use of Raman microspectroscopy as an IC diagnostic tool was attempted. Twenty-two partici...
Fourier Transform Infrared (FTIR) spectroscopy is finding increasing biological application, for example in the analysis of diseased tissues and cells, cell cycle studies and investigating the mechanisms of action of anticancer drugs. Cancer treatment studies routinely define the types of cell-drug responses as either total cell destruction by the drug (all cells die), moderate damage (cell det...
The boron-rich cobaltabisdicarbollide (COSAN) and its 8,8'-I2 derivative (I2-COSAN), both of purely inorganic nature, are shown to accumulate within living cells, where they can be detected using νB-H Raman microspectroscopy. This demonstrates an alternative method for cell labelling and detection.

The analysis of environmental occurrence microplastic (MP) particles has gained notable attention within the past decade. An effective risk assessment MP litter requires elucidating sources particles, their pathways distribution and, ultimately, sinks. Therefore, sampling to be done in high frequency, both spatially and temporally, resulting a number samples analyze. Microspectroscopy technique...

PURPOSE Synchrotron-based radiation (SRS) Fourier-transform infrared (FTIR) microspectroscopy potentially provides novel biomarkers of the cell differentiation process. Because such imaging gives a "biochemical-cell fingerprint" through a cell-sized aperture, we set out to determine whether distinguishing chemical entities associated with putative stem cells (SCs), transit-amplifying (TA) cells...
Vibrational spectroscopy, based on either infrared absorption or Raman scattering, has attracted increasing attention for biomedical applications. Proof of concept explorations diagnosis oral potentially malignant disorders and cancer are reviewed, recent advances critically appraised. Specific examples applications microspectroscopy analysis histological, cytological saliva samples presented i...
