Histologic analysis of a stained tissue sample by a trained pathologist forms the definitive diagnosis of prostate cancer. Rapid and objective second opinions are highly desirable to make more accurate diagnostic decisions. One alternate method is to use Fourier transform infrared (FT-IR) spectroscopic imaging, which is an emerging technique that combines the molecular selectivity of spectroscopy...
We report the use of bimaterial microcantilever sensors for sensing narrow-band infrared (IR) radiation generated by a monochromator and its application to IR spectroscopy of polymer films. We selected microcantilever sensors of either silicon or silicon nitride and having a thin metal film coating. To assess the IR measurement capability of these cantilevers, the IR sensitivity to noise ratio (SNR),...
Current latent print and trace evidence collecting technologies are usually invasive and can be destructive to the original deposits. We describe a non-invasive vibrational spectroscopic approach that yields latent fingerprints that are overlaid on top of one another or that may contain trace evidence that needs to be distinguished from the print. Because of the variation in the chemical composition...
