Nonfouling, zero background surfaces for biomedical research.
Our proprietary technology has allowed us to coat glass, silicon wafer, quartz, & other substrates with a robust, high density layer of poly-ethyleneglycol (PEG). The PEG coating is intrinsically inert towards the adsorption of proteins, cells and other biomolecules, thus providing a zero-background starting surface in a variety of biomedical experiments. Regions of PEG molecules may be selectively removed by lithographic techniques to prepare micro- or nano-patterned surfaces. On the other hand, standard bio-conjugation chemistry may be used to covalently link biomolecues to the otherwise zero background brush.
