Here, we demonstrate an ultrasensitive olfactory system, namely, a bioelectronic nose (B-nose), based on CMOS-compatible silicon nanowires (SiNWs) conjugated with an odorant-binding protein (OBP). The SiNWs were low-cost and top-down fabricated with a conventional microfabrication process by using a novel controllable size-reduction process. The OBP-SiNW devices detect vapor analytes under ambient...
This paper propose a novel method of integration microfluidic sample delivery system with silicon nanowire (SiNW) biosensor device, which provide multiplexed detection capability as well as protect the fragile sensing elements from mechanical shocks and surrounding impurities. The SiNWs and PDMS chips were fabricated with complementary metal oxide semiconductor (CMOS) compatibility and low cost methods...
DNA origami, in which a long single strand of DNA is folded into a shape using shorter ‘staple Strands’, promises low-cost ways to create nanoscale shapes and can even display patterns of binding sites of 6-nm-resolution, in principle allowing complex arrangements of carbon nanotubes, silicon nanowires, or quantum dots [1]. However, adsorption of origami appears better results on mica substrate, which...
A new process method is developed to fabricate beam into nanometer scale in width. Assisted by Focused ion beam (FIB), one 122 nm silicon nanobeam is obtained on (110) Silicon-On-Insulator (SOI) substrate, based on the material and process properties of crystal silicon. After KOH etching, sidewalls with (111) terminations are all vertical to (110) surface plane. This presented process method has some...
A single-wafer-processed high-g piezoresistive accelerometer is reported. The microsensor has an in-plane self-caging cantilever configuration, in which an electrostatic self-testing function is integrated on-chip. Both the sensing piezoresistors and the self-test actuating electrodes are integrated on vertical sidewalls of the laterally deflecting cantilever. For single-wafer-based fabrication of...
