Description
- Abstract
- Abstract this phase II project aims to develop and commercialize video rater photothermal infrared (VR-ptir) imaging and spectroscopy. The proposed VR-ptir will provide 10-30X better spatial resolution than conventional IR spectroscopy and will operate up to 1000X faster than previous photothermal infrared microscope systems. Infrared (IR) spectroscopy can provide rich analysis of molecular bonds and has been used in life sciences research to study tissue classification, drug/tissue interaction, neurodegenerative diseases, cancer, and other areas. Conventional IR spectroscopy, however, has a fundamental spatial resolution limit (i.e., roughly how small an object IT can analyze) of around 10 micrometers, similar to the size of an average biological cell. Thus, conventional IR spectroscopy has been extremely limited for many biomedical applications where the structures of interest are smaller than a cell. Optical photothermal infrared (o-ptir) is a rapidly emerging field that uses a tightly focused visible probe beam to detect infrared absorption in samples with
