Abstract
There is a great interest to quantitatively manipulate, separate, and deliver low concentrations or even single biomolecules in submicrometer-sized channels. We report the use of cross-linked four-star polyethylene glycol (PEG) as a new coating technique for microchannels. PEG-coating efficiently reduces the electroosmotic flow (EOF) and non-specific adsorption to the glass walls. Our results demonstrate that individual fluorescently labeled hydrophobic cell adhesion proteins (fibronectin molecu
