Spring 2017
One of the central puzzles concerning the interaction of low Reynolds number (Re<<1) fluid transport with bacterial biomass is the formation of filamentous structures called bacterial streamer. Bacterial streamers can be tethered at one or both ends to solid surfaces, while the rest of the...

Electro-transmittance of molecular junctions was characterized electrically and studied optically at 410nm and 532nm. Between 1kHz and 100kHz there was no qualitative difference between the control samples and the molecular junction samples, however there were difficulties with reproducibility of...

Combination of AC electrothermal and Dielectrophoresis realized by 3D Electrodes to Concentrate Particles
Download2022-06-01
Fathy, Jino, Wang, Ziying, Lai, Yongjun
In this paper, a particle microconcentrator is designed and simulated that works by combining the AC electrothermal (ACET) and Dielectrophoresis (DEP) forces. The microconcentrator consists of a PMMA channel with copper electrodes on the walls and bottom of the channel. On each side of the...

Design and Microfabrication of Robust and Highly Integrated Thermal Lab-On-A-Chip Polymeric Systems for Genetic Diagnosis
DownloadSpring 2014
The lab-on-chip (LOC) technology could transform and greatly enhance the health care system by making genetic diagnosis tests fast, accurate and readily accessible. However, most LOC systems are not prepared to resist variations of their external environment, as they depend upon many...

Development of a Multisectorial Electroactive Nanowell Platform for Selective Single-Cell Sorting and Quantification
DownloadSpring 2022
The rapid isolation of specific rare target cells is of rising importance in current targeted patient treatment plans. Common cell sorting approaches such as stream-based dielectrophoresis (DEP) based cell sorters are limited by their spatial dimensions as only a number of cell types...
