A novel process for self-assembly of metal-porphyrins on oxide dielectrics is developed and utilized for continuous work function tuning. Simply by changing the central metal atom present at the core of porphyrin helps change the dipole moment at the metal-dielectric interface leading to change in work function. Further the development of vapor phase process makes the process of the self-assembly...
We report a novel microfluidic-based high-throughput electrorotation flow cytometer for label-free single-cell analysis in continuous flows. This is realized by a heterogeneously integrated microfluidic channel with electrodes for high precision 3D single stream focusing and electrorotation of cells in high speed flows. This device provides 4 orders of magnitude higher throughput than prior electrorotation...
This paper reports on utilizing a hydrogel for surface immobilization of various reagents in a microfluidic dielectric sensor for blood coagulation monitoring. The top inner surface of the microfluidic sensor is coated with either pure or bio-active polyethylene glycol (PEG), which is immobilized by photo-crosslinking using ultraviolet (UV) light. The coagulation time of healthy human whole blood...
Electrostatics especially electrostatic force (ESF) plays vital role in a variety of fields, concerning applications in colloid, plasma, and micro/nano device driving. The behaviors of ESF under different conditions were studied both by simulation and experiment in this paper. Voltages or charges were set to spheres of several materials, in order to explore how ESF was influenced by the electric condition...
