Since the middle of 20 th century infrared (IR) spectroscopy coupled to microscopy (IR
microspectroscopy) has been recognized as a non destructive, label free, highly sensitive …

Biospectroscopy is employed to derive absorbance spectra representative of biomolecules
present in biological samples. The mid-infrared region (λ= 2.5 μm− 25 μm) is absorbed to …

This paper reports the first use of a novel completely optically based photothermal method
(O-PTIR) for obtaining infrared spectra of both fixed and living cells using a quantum …

The magnitude of infectious diseases in the twenty-first century created an urgent need for
point-of-care diagnostics. Critical shortages in reagents and testing kits have had a large …

Early diagnosis of oral cancers, one of the major cancers, is of utmost importance as 5-year
disease-free survival rates are some of the lowest, despite advances in treatment and …

Transmission and transflection infrared microscopy of biological cells and tissue suffer from
significant baseline distortions due to scattering effects, predominantly resonant Mie …

Mid-infrared spectroscopy using Fourier transform infrared (FTIR) with attenuated total
reflectance (ATR) correction was coupled with partial least square regression (PLSR) for the …

Cancers of oral cavities are one of the most common malignancies in India and other south-
Asian countries. Tobacco habits are the main etiological factors for oral cancer. Identification …

Discrimination/classification of biological material a ta molecular level is one of the key aims
of chemometrics applied to biospectroscopic data. Two discriminant functions, namely …

Occurrence of metachronous and synchronous secondary tumors in oral cavities has been
associated with poor prognosis and decreased 5-year disease-free survival rates. The origin …
