Outline of Final Research Achievements

Detection of peripheral nerve tissues during surgery is required to avoid neural disturbance following surgery as an aspect of realizing better functional outcome. In this study, we developed a Raman microspectroscopic system for label-free and noninvasive detection of peripheral nerves. Firstly, we constructed a Raman microspectroscope with near-infrared excitation light for deep tissue detection. Secondly, we obtained Raman spectra of peripheral nerves including myelinated nerves and unmyelinated nerves, and their adjacent tissues such as fibrous connective tissue, skeletal muscle, tunica media of blood vessel, and adipose tissue, and extracted Raman spectral features for each tissue species. Thirdly, we developed a multivariate spectral analytical method for selective detection of peripheral nerves. Our results provided feasibility of Raman microspectroscopy for molecular analysis of peripheral nerves and for selective detection of peripheral nerves in clinical use.
