Reactive Particles for Cold Spray Coatings
This invention demonstrates solid or semi-solid microparticles that undergo crosslinking and polymerization upon contacting a substrate to form a coating. The microparticles are maintained in an un-reacted state until delivered using cold spray processes where they are propelled using a gas stream at a pre-determined temperature and velocity. The process does not require volatile organic solvents or aqueous vehicles, nor plural component spray or two component formulations with limited shelf life but still deliver uniform coating.

Noncationic Nucleic Acid-Polymer Complexes for Nucleic Acid Delivery
This invention provides a new strategy for nucleic acid delivery by using novel cross-linkable and surface-charge modifiable synthetic polymers. The use of the novel polymer system allows for robust nuclecid-polymer complexation, easy removal of cationic moieties of the polymer and self-crosslinking of the polymer in a single step, and stimuli-responsive release of the nucleic acid molecules in the cell.

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.
