Tailoring PAS Design for Bacterial Detection (332)
Problem: Need to simplify sensor system for detection of bacteria to provide cost effective, field portable, robust sensor
Project Activity Scope (from Technical Overview Chart): Mechanisms through Intstruments
PNNL Solution:
- Individual bacteria detection requires a limited number of measurement wavelengths
- Advanced analysis of spectra for target and probable interferent bacteria allows selection of key measurement wavelengths
- Allows simplified sensor system using fixed wavelength sources
Capabilities Employed to Meet Client Needs: Spectroscopic understanding of molecules and bacteria; use of electronics to collect data; data processing and analysis; understanding and operation of FT-infrared spectrometers for spectra characterization; microbiological techniques in cell culturing; statistical analysis of large, complex data sets, data analysis to obtain key chemical and biological information; reporting of findings (including numerous open literature publications).
