Nanogen of San Diego has received US Patent No. 6,838,053, “Platinum silicide permeation layer device with microlocations.” The patent covers electronically addressable microchips having covalently bound permeation layers and methods of making such covalently bonded permeation layers to microchips. The covalent bonding is derived from combining the use of electrodes with silane derivatives. Such chemistry provides the ability to apply an electronic bias to the electrodes of the microchip while preventing permeation layer delaminating from the electrode surface.
