Engineering micro-perfusable scaffolds for MesoPhysiological Systems using projection Micro-StereoLithography
MicroPhysiological Systems (MPS) are in vitro models that capture the complexity of human organs at miniature scale by recreating the native microenvironment of resident cells. These systems offer promising alternatives to in vivo animal models for the development of new drugs, disease modeling and …

Modeling and simulation of micro/nano-rod distribution in micro channel flows
<p>"The behavior of a typical nanorod particle in microscale flows was theoretically investigated, considering the effect of the wall on the rotational and translation motions of the non-spherical particle. Initially, a systematic method using Brownian dynamics simulation of the rotational motion …

Electrostatic Micro Gas Pumping for Micro Gas Chromatography Systems---Fabrication and Experiments
For the pump to perform as designed, the diaphragm has to fully zip and the inlet/outlet valves need to open and close as the diaphragm actuates. As an actuation compresses gas, the outlet valve should open with the inlet valve closed so that the gas flows out. As the diaphragm releases, the outlet …
