Abstract: Devices, systems, and methods for detecting protein-nucleic acid and cell-nucleic acid hybridization, using surface-tethered aptamer probes, without the use of labeling or target modification and capable of recycling.

Abstract: The present invention provides a hybrid coupling structure of a short range surface plasmon polariton and a conventional dielectric waveguide, including a dielectric substrate layer, a dielectric waveguide layer positioned on the said dielectric substrate layer, a coupling matching layer positioned on the said dielectric waveguide layer and a short range surface plasmon waveguide portion, formed on the said coupling matching layer, for conducting the short range surface plasmon polariton. The present invention also provides a coupling structure of a long range surface plasmon polariton and a dielectric waveguide, including a dielectric substrate layer, a dielectric waveguide layer, a coupling matching layer and a long range surface plasmon waveguide portion upward from below respectively.

Abstract: A handwriting recognition system with a wireless pen and a tablet. The wireless pen has an eraser button which is used to let an eraser mode be performed while the eraser button being process, the tablet receive messages from wireless pen and decide the location of wireless pen and current mode of handwriting recognition system. The method of using the handwriting recognition system at least has follows. Move the wireless pen over the tablet so let these messages be received by the tablet, and switch the current mode of the handwriting recognition system between an eraser mode and a writing mode. however, the terminal with coil of the wireless pen always is more closed to the tablet than the other terminal.
