Nanopore Tweezer System for Protein Kinase Allosteric Drug Screening
Protein kinases are enzymes that catalyze the phosphorylation of substrate proteins, regulating a wide range of cellular pathways. Aberrant kinase activities are implicated in various human diseases, making the kinases essential drug targets. This invention provides a nanopore-tweezer-based compound screening platform for the identification of allosteric drugs that can bind to allosteric sites on protein kinases and overcome drug resistance.

Economical Surface Treatment for Harvesting Epithelial Cells from Biological Fluids
This invention provides economical, bio-interactive surfaces and surface treatment methods for selective capture of targeted epithelial cells or other cell types from cell mixtures or complex biological fluids. Preparation or fabrication of the engineered surfaces provided by this technology does not require the use of expensive and unstable biomolecular materials, and the resulting surfaces can distinguish different cell types or cells that express different levels of the same surface adhesion marker. Such engineered surfaces can be used as economical tools for assessment of cancer risk, cancer diagnosis, and tracking of the effectiveness of cancer treatments, among other potential applications.

RENEWABLE SURFACES FOR CAPTURE, KILLING AND RELEASE OF BACTERIA
This invention provides economical, renewable surfaces and related methods for selective capture of bacteria in a fluid medium and for killing and/or release of the captured bacteria. The fabrication of these surfaces or surface-treated substrate materials does not require the use of expensive biomolecules and toxic chemicals. The surfaces capture and kill bacteria on contact without leaching any toxic antimicrobial agents. The surfaces can rapidly release captured or killed bacteria via mechanical means, and thus are easily renewable for subsequent round of bacterial capture, killing and release, which makes them ideal for use in on-line bacterial sensor systems. In addition, the surfaces can be engineered to selectively capture bacteria from complex fluid media or selectively capture one bacterial strain over another.
