Paper Abstract

Traditionally methods for the detection of excitatory amino acids, which have been linked to secondary injury following head trauma, can be excessively time consuming clinically. A near real-time measurement system could provide clinical information in anticipation of pharmaceutical intervention for head injured patients. Our studies have shown that surface-enhanced Raman spectroscopy (SERS) with silver colloids has the ability to measure physiological concentrations of in vitro excitatory amino acids using short scan times. Employing a damage model for ischemia, preliminary ex vivo rat extracellular grain fluid analysis shows an intriguing correlation between SERS spectral features and expected Glutamate concentration fluctuations following head injuries.
