For example, a maskless array synthesizer (MAS) can be used to synthesize about 800,000 70-mer oligonucleotides on a glass microscope slide. Then the slide is divided into 96 pieces, each containing about 30,000 of the 70-mer DNA sequences. These small pieces can be used in any experiment that uses standard DNA chips.
Because the millichips are small, less than 10 cubic centimeters, small volumes of solutions can be used for analysis. In addition, the small substrate size allows the arrays to be visualized using instrumentation readily available in research laboratories.
Unlike competing technology, the nanopores feature both genetically and electrically engineered components. They can be constructed of DNA attached with metal particles to enhance electromagnetic wave reception. This is achieved by replacing the side chains of the DNA molecule with sulfur groups that in turn link to gold particles. Metalized DNA strands or ‘arms’ can be added to increase antenna size and tune polarization.
Once bonded to the flexible substrate, the whole structure is stretched, causing biaxial tensile strain. Given sufficient strain, the Ge is transformed into a direct-bandgap semiconductor. When voltage is applied, radiation is emitted via electroluminescence. The wavelengths of the emitted radiation can be tuned by adjusting the amount of stretch (i.e., the amount of tensile strain) that is applied.
