A practical guide for the fabrication of microfluidic devices using glass and silicon

Ciprian Iliescu, Hayden Taylor, Marioara Avram, Jianmin Miao, and Sami Franssila

The authors describe protocols used for fabricating microfluidic devices from glass and silicon. Conventional methods for micropatterning glass and silicon are surveyed, and their limitations discussed. The authors conclude much work needs to be done to develop micro- and nano-fluidic fabrication techniques further and to integrate features with widely ranging length-scales into glass/silicon devices.

Electrotaxis of lung cancer cells in ordered three-dimensional scaffolds

Yung-Shin Sun, Shih-Wei Peng, Keng-Hui Lin, and Ji-Yen Cheng

A new method to incorporate 3D scaffold with electrotaxis measurement in the microfluidic device. The electrotactic response of lung cancer cells in the 3D foam scaffolds which resemble the in vivo pulmonary alveoli may give more insight on cellular behaviors in vivo.

Effects of chain stiffness and salt concentration on responses of polyelectrolyte brushes under external electric field

Qianqian Cao, Chuncheng Zuo, Lujuan Li, and Guang Yan

The authors address the effects of salt concentration and chain stiffness on conformational transition and dynamic response of polyelectrolyte brushes under added electric fields. Their results are helpful for the design of soft smart valves in biomimetic nanofluidic channels.
