摘要:
A method of manufacturing a probe includes: forming a first slant face of the probe through an anisotropic etching process using a first etching mask pattern formed on a silicon substrate; forming a first semiconductor electrode region; forming a second etching mask pattern in an opposite direction of the first etching mask pattern on the silicon substrate; forming a spacer layer on a side wall of the second etching mask pattern; forming a second slant face of the probe; forming a second semiconductor electrode region; forming a silicon oxide layer pattern on the resulting silicon substrate; forming spacer layers on both side walls of the silicon oxide layer pattern; and etching the silicon substrate to a predetermined depth.
摘要:
A method of manufacturing an enhancement type semiconductor probe and an information storage device having the enhancement type semiconductor probe are provided. The method involves using an anisotropic wet etching and a side-wall in which influence of process parameters upon the performance of a device is reduced to improve reliability of the device in mass-production, and factors of degrading measuring sensitivity is removed to improve the performance of the device.

摘要:
The present invention features a microfluidic device for detecting Escherichia coli. The device comprises (a) a base slide having a first inlet and a second inlet, both of which connect at a vertex, where the first inlet is for accepting beads conjugated with anti-E. coli and the second inlet is for accepting a sample, wherein at the vertex the beads conjugated with anti-E. coli and the sample combine to form a combined mixture; (b) a portable spectrometer and a light source; and (c) a first fiber optic cable for directing an incident light into the combined mixture and a second fiber optic cable for detection of light scattering from the combined mixture, where the fiber optic cables are arranged in a proximity fiber arrangement, with the second fiber positioned above the base slide so as to detect forward light scattering at about a 45° angle.
