A novel hydrogel copolymer, a substrate coated with the copolymer, a method of producing a microarray using the copolymer, and a microarray produced by the method are provided. This apparatus includes a first electrode disposed in a stacked relationship with a second electrode. The virtual device communicates with other devices within the local network as if it is the actual mobile device. The map returns a self-help search string that, upon execution in a search engine, is expected to return relevant search results. The device may provide state information associated with the second audio andor video configuration via a first session initiation protocol message.
