Abstract
Raman spectroscopy represents a label-free vibrational spectroscopic technique for studying the biochemical and biomolecular compositions of human body. Raman probe is a key component to facilitate the in vivo diagnosis by using Raman spectroscopy. We investigated a compact Raman needle probe design to be integrated into a device that can also take biopsies of solid tissues for cytological assessment, enabling concurrent Raman spectroscopic interrogation and fine needle aspiration biopsy with a single needle penetration. We described the fabrication of the Raman needle probe and its assembly with the biopsy device. Example Raman spectra of various solid tissues are given.
