A novel low-temperature, pressureless bonding approach by electroless plating with controlled flow through a microfluidic device, in which a laminar forced convection flow of electroless solution was passing through a microchannel between dies and to gaps between copper pillars, was developed to metallically interconnect copper pillars together. Previous study had been demonstrated that, with the...
A scalable method for fabricating architected materials well‐suited for heat and mass exchange is presented. These materials exhibit unprecedented combinations of small hydraulic diameters (13.0–0.09 mm) and large hydraulic‐diameter‐to‐thickness ratios (5.0–30,100). This process expands the range of material architectures achievable starting from photopolymer waveguide lattices or additive manufacturing...
This paper presents a novel non-invasive micromanipulation technique where a microrobot swimming in a three-dimensional space through electromagnetic actuation manipulates micro-objects using an acoustically oscillating bubble attached on the microrobot as a grasping tool in an aqueous environment. The concept of the micromanipulation method is experimentally proved along with studying both electromagnetic...
We report the implementation of a fully on-chip, lensless, sub-pixel resolving optofluidic microscope (SROFM) based on the super resolution algorithm. The device utilizes microfluidic flow to deliver specimens directly across a complementary metal oxide semiconductor (CMOS) sensor to generate a sequence of low-resolution (LR) projection images, where resolution is limited by the sensor's pixel size...
We report on the implementation of a color-capable sub-pixel resolving optofluidic microscope based on the pixel super-resolution algorithm and sequential RGB illumination, for low-cost on-chip color imaging of biological samples with sub-cellular resolution.
Separations of complex proteomes are required to fractionate components before downstream identification and quantification of individual protein species. Twodimensional gels based on a combination of isoelectric focusing (IEF) and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) have been a core technology for real-word detection of thousands of proteins, and microfluidic systems...
Fabrication of a temperature sensor array and a heater in a complicated heat transfer microchannel system, on a glass substrate, is presented. In addition to the glass substrate, low thermal conductivity materials such as SU-8, PMMA plate are selected to form the micro channel wall to provide good thermal insulation. Both the titanium and the platinum are deposited sequentially on a glass plate and...
