  • Publication number: 20050208576
    Abstract: Methods are provided for producing an array of immobilized nucleic acids on an array device. The array device has a plurality of microlocations each having an electrode. At least one of the microlocations has a synthetic addressing unit coupled to the microlocation. The microlocation is the activated, usually by electronically biasing the electrode of the microlocation. The at least one microlocation is then contacted by a conjugate which has a nucleic acid and a synthetic binding unit. The conjugate is then coupled to the microlocation through an interaction between the synthetic binding unit and the synthetic addressing unit. In one embodiment, the synthetic binding unit and synthetic addressing unit may be pRNA, pDNA, or CNA.
