High-Performance Preconcentrator Materials (277)

Problem: Need rapid preconcentration with good selectivity to improve measurement of target analyte concentrations

Increasing Dimensional Scale to Materials for Practical Use graphic

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.
