We have demonstrated multi-walled carbon nanotube (MWCNTs) based sensors, which are capable of detecting alcohol vapor with ultra-low power. We fabricated the Si-substrate sensors using an ACExpand
Hybrid electrokinetic manipulation in high-conductivity media.
It is shown that pathogenic bacteria and biowarfare agents can be concentrated for over 3 orders of magnitude using hybrid electrokinetics, and the major technical hurdle of electrode instability for manipulating high conductivity samples is tackled. Expand
Electrothermal Fluid Manipulation of High-Conductivity Samples for Laboratory Automation Applications
Electrothermal flow was shown to create fluid motion for samples with a wide range of conductivity when the driving frequency was greater than 100 kHz and the characteristics of the electrothermal fluid motions were in quantitative agreement with the theory. Expand
Integrated Biosensor Assay for Rapid Uropathogen Identification and Phenotypic Antimicrobial Susceptibility Testing.
The integrated biosensor platform achieved microbiological results including MIC comparable to standard culture in a significantly shorter assay time, and has the potential to significantly expedite and improve treatment of urinary tract infections. Expand
