Methods for Infrared Spectral Sensing of Chemical and Biological Matter at the Microscale : Theory and Experiments

The use of infrared spectroscopy for biological and clinical applications has been demonstrated by a large number of proof-of-principle studies showing a high sensitivity and specificity for disease detection. Infrared spectroscopy was also proven to be efficient for the analysis of biomarkers in biological fluids such as blood, saliva, and urine.
