BEADS*: A Basic Tool for Bio-Detection (255)
Problem: Detect biological DNA, RNA, and protein signatures with high specificity and high sensitivity in dirty environments
*BEADS: Biodetection Enabling Analyte Delivery SystemProject Activity Scope (from Technical Overview Chart):
Mechanisms through Integrated Systems
PNNL Solution:
- Use micro-beads for automated analyte purification and concentration
- Micro-Beads provide high specificity collection, concentration, and separation of whole cells, proteins, or nucleic acids
- Employ transduction based on optical, mass or charge discrimination
Capabilities Employed to Meet Client Needs: Bead attachment chemistry; antibody development; renewal filter system development; bead handling methodologies; sample cell design for reliable bead exchange (rotating rod concept); fluidic systems; interface requirements to multiple sensor/detection technologies.
