High-Performance Preconcentrator Materials (277)
Problem: Need rapid preconcentration with good selectivity to improve measurement of target analyte concentrations
Project Activity Scope (from Technical Overview Chart): Mechanisms through Sensors and Devices
PNNL Solution:
- Tailor molecules to provide specific affinity for target analyte and/or transduction or signaling mechanism
- Restrict molecular mobility while preserving functionality
- Scale still too small for most practical uses
- Incorporate into materials that provide high effective density of functional sites while maintaining functionality
- Extend to usable useable detector structures while maintaining properties
Capabilities Employed to Meet Client Needs: Material science (including self-assembling monolayers, ceramic materials, etc.); chemistry including surface chemistry & molecular interactions; molecular recognition mechanics; materials processing into specific morphologies (e.g., membranes, thin films, capillaries, etc.); materials characterization.
