Nanomaterials for Selective Preconcentration (271)
Problem: Need materials that rapidly capture and tightly bind target analytes with good chemical selectivity and stability
Project Activity Scope (from Technical Overview Chart): Mechanisms through Sensors and Devices
PNNL Solution:
- Previous preconcentrator materials were often slow, leachable, and not very selective
- PNNL developed selective monolayer chemistry for highly selective sorption
- Embedding the self-assembled monolayers into nanoporous ceramic matrices provided significant improvement, both in terms of chemical selectivity and binding efficiency
- High binding affinities (104 to 108) for target analytes demonstrated in the lab
Capabilities Employed to Meet Client Needs: Organic synthesis, molecular self-assembly; templated synthesis of nanoporous ceramics; nano-technology; surface chemistry; glass chemistry; separations chemistry and processes; material sciences including polymers and ceramics; materials synthesis and performance evaluation.
