Journal ArticleDOI
A fast cell loading and high-throughput microfluidic system for long-term cell culture in zero-flow environments.
TL;DR: A controlled loading at single cell level and the phenotypic variation of gene expression of the yeast strain w303 as a function of copper ion concentration of the medium are shown.
Journal ArticleDOI
Frequency-dependent Escherichia coli chemotaxis behavior.
Xuejun Zhu,Guangwei Si,Nianpei Deng,Qi Ouyang,Tailin Wu,Zhuo-Ran He,Lili Jiang,Chunxiong Luo,Yuhai Tu,Yuhai Tu +9 more
TL;DR: A new continuum model is proposed to describe the population level behavior of E. coli chemotaxis based on the underlying pathway dynamics with the inclusion of a finite adaptation time and an attractant consumption rate that successfully explains the microfluidic experiments at different stimulus frequencies.
Journal ArticleDOI
Confined three-dimensional plasmon modes inside a ring-shaped nanocavity on a silver film imaged by cathodoluminescence microscopy.
Xuejun Zhu,Yan-Qing Ma,Jinzhong Zhang,Jian Xu,Xiaofei Wu,Youyi Zhang,Xiaobing Han,Qiang Fu,Zhi-Min Liao,Li-Kun Chen,Dapeng Yu +10 more
TL;DR: The confined modes of surface plasmon polaritons in boxing ring-shaped nanocavities have been investigated and imaged by using cathodoluminescence spectroscopy, indicating that the electron beam locally excites the out-of-plane field component of surface Plasmon Polaritons.
Journal ArticleDOI
Angle sensing in magnetotaxis of Magnetospirillum magneticum AMB-1
Xuejun Zhu,Xin Ge,Ning Li,Long-Fei Wu,Chunxiong Luo,Qi Ouyang,Yuhai Tu,Yuhai Tu,Guanjun Chen +8 more
TL;DR: The results reconciled the two putative models for magnetotaxis and revealed a key molecular component in the underlying magneto-sensing pathway.
Journal ArticleDOI
Microfluidic generation and dynamically switching of oxygen gradients applied to the observation of cell aerotactic behaviour
TL;DR: In this paper, a single layer patterning of polydimethylsiloxane (PDMS) and integration of a thin layer polyvinylidene chloride (PVDC) was proposed for the generation of oxygen gradient in microfluidic devices, which is useful for cell aerotaxis study.
