Superhydrophobic and Superhydrophilic Surfaces for Cell Trapping

Superhydrophilic and superhydrophobic patterned surfaces are fabricated from silicon through plasma etching and a plasma coating. These surfaces are optimized for their wetting properties. The superhydrophobic surfaces consist mostly of air which also makes them extremely repellent toward the adhesion of cells, at least in short term. The wettability patterned surfaces are utilized for single-cell trapping of immune cells and in the future, the aim is to apply them in single-cell metabolomic and transcriptomic analysis.
