Selective Material Patterning for Sensors (391)
Problem: Need methods to localize sensor coating materials on specific small scale regions of the device surface.
Project Activity Scope (from Technical Overview Chart): Mechanisms through Sensors and Devices
PNNL Solution:
- Develop photopatterning method to produce sorptive polymers in needed patterns directly on devices
- Patterned polymer retains physical and chemical properties desired for chemical sensing
- Methods allow chemically diverse set of polymers can be patterned for sensors and arrays
Capabilities Employed to Meet Client Needs: Polymer synthesis; thin polymer film application methods; photopatterning method adaptation for sensors; thin film characterization; multiple sensor test platforms; sensor performance testing including response characterization and calibration; performance comparison of "large area" thin films and photopatterned thin films to validate method efficacy.
