Focusing particles by induced charge electrokinetic flow in a microchannel
Li, Dongqing; Song, Yongxin; Wang, Chengfa; Pan, Xin-xiang; Li, Mengqi (Wiley, 2016-02-16)A novel method of sheathless particle focusing by induced charge electrokinetic flow in a microchannel is presented in this paper. By placing a pair of metal plates on the opposite walls of the channel and applying an ... -
A novel microfluidic resistive pulse sensor with multiple voltage input channels and a side sensing gate for particle and cell detection
Zhou, Tong; Song, Yongxin; Yuan, Yapeng; Li, Dongqing (Elsevier, 2019-04-04)Traditionally, a resistive pulse sensor (also known as Coulter counter) works by letting a particle pass through a small orifice in an electrolyte solution. The detection sensitivity mainly relies on the volume ratio of ... -
Thin liquid film between a floating oil droplet and a glass slide under DC electric field
Zhang, Junyan; Song, Yongxin; Li, Dongqing (Elsevier, 2019-01-15)Hypothesis The shape of the liquid film (SLF) between a glass slide and an oil droplet immersed in an aqueous solution is influenced by the direct current (DC) electric field. The liquid film, consisting of the central ...
