Improvements in Raman instrumentation and techniques has enabled reduced signal collection time, allowing for the possibility of practical clinical and biomedical applications.
For instance, this technology has been used for the study of percutaneous absorption of drugs or creams, as well changes in protein damage in the skin. In vivo studies have been conducted for the detection of malignant and pre-malignant skin cells, at times without requiring biopsy.
Raman spectroscopy has been able to identify the chemical composition of atherosclerotic plaques (calcified vs. lipid-rich). Determining the composition could play a role in risk assessment and determine the appropriate therapy to pursue.
In addition, Raman spectroscopy has been useful in identifying pathological microorganisms. Compared to the typical 2-3 day turnaround time to run microbiological tests, Raman spectroscopy could be used to identify the sample within that day. This would allow faster treatment for patients and may result in shorter hospital stays.
