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.
