We have demonstrated DNA handling with micromachined nanotweezers that consist of a pair of opposing nanoprobes and integrated thermal expansion microactuators for changing the probe gap. The probe tips coated with a thin Al layer were dipped into a droplet of a solution containing lambda-DNA molecules labeled with fluorescence dye, and then an ac electric(More)
This paper proposes a multi-probe SPM using fringe patterns which is able to measure the large area. The composition of the chip accumulates 50,000 probes in the area of 5 mmtimes5 mm. We fabricated the multi probes, and by using the chip the fringe patterns image could be taken with the CCD camera
This paper describes a new fabrication process of a micro elliptical collimator lens to form a beam shape for LD (laser diode), and the evaluation results of the optical characteristic for this lens. Beam shape of LD is an ellipse because divergent light angle is different between horizontal and vertical direction, which increases a coupling loss with an(More)
