We report sub-20 nm sacrificial nanochannels that enable stretching and translocating single DNA molecules. Sacrificial silicon nano-structures were etched with XeF2 to form nanochannels. Translocations of linearized DNA single molecules were imaged by fluorescence microscopy. Our method offers a manufacturable wafer-scale approach for CMOS-compatible bio-chip platform.
The first successful demonstration of virus-structured, hierarchical electrodes for three-dimensional (3-D) Li-ion microbattery architectures is reported in this paper. The electrodes consist of electroplated gold micropillars and virus-structured nanocomposite materials with a TiO2 anode layer deposited on a nickel-coated viral template. Micropatterning increases the active electrode surface area...
