We have integrated electronic, optical, magnetic, thermal and fluidic devices into systems to construct useful analysis tools. Over the past several years, we have developed soft lithography approaches to define microfluidic systems in which pico-Liter volumes can be manipulated. These fluidic delivery systems have more recently been integrated with optical and electronic devices. We have also ...
Enhancement of heat and mass transfer and decrease of energy dissipation are great necessities of the evolution of fluid flow devices. Utilizing oscillatory or pulsatile fluid flow for periodic disturbing of velocity and thermal boundary layers is one of the methods with exciting results. Passive methods of generating oscillatory flow are preferred to active methods because of simplicity, no ne...
Using dissipative particle dynamics (DPD) simulations, we model the interaction between nanoscopic lipid vesicles and Janus nanoparticles in the presence of an imposed flow. Both the vesicle and Janus nanoparticles are localized on a hydrophilic substrate and immersed in a hydrophilic solution. The fluid-driven vesicle successfully picks up Janus particles on the substrate and transports these ...
Paper biosensors: an origami sensor is printed on a single piece of paper, folded into a three-dimensional fluidic device, and encapsulated by thermal lamination. Aptamer is trapped in the fluidic channel, where it binds to the target and releases an enzyme to generate a signal. The device is read out using a digital multimeter.
In 3D system design, effective thermal cooling for high power density 3D stacked ICs is a crucial bottleneck. In this paper, efficient thermal simulation with micro-channel fluidic cooling and air convection boundary condition is presented. By employing the analytical model for micro-fluidic cooling, the fluid flow rate can be efficiently optimized to achieve target chip temperatures. Results d...
We describe quantitatively effects of nonlinear transfer phenomena that drive energy generators (thermal engines) and heat pumps. it is shown that these transports can be treated either in a standard way or as peculiar chemical reactions described by appropriate affinities. An approach to nonlinear transports links heat fluxes with differences of temperature in certain power t. a more recent ap...
In recent years, Fluorescent Melting Curve Analysis (FMCA) has become an almost ubiquitous feature of commercial quantitative PCR (qPCR) thermal cyclers. Here a micro-fluidic device is presented capable of performing FMCA within a microchannel. The device consists of modular thermally conductive blocks which can sandwich a microfluidic substrate. Opposing ends of the blocks are held at differin...
