Biofunctionalization of laser-ablated gold nanoparticles

Riabinina D., Zhang J., Zhang T., Zhang J., Zhang T., Chaker M., Ma D., Tijssen P., Universite du Quebec, CA

For the first time, we investigated the biofunctional activity of gold nanoparticles prepared by nanosecond pulsed laser ablation in liquid media. This method allows the fabrication of gold nanoparticles surrounded by a metastable gold oxide [...]

Reliability of Self-assembled Hydropobic Coatings: Chemical Resistance and Mechanical Durability

Kobrin B., Zhang T., Grimes M.T., Chong K., Nowak R., Chinn J., Applied Microstructures, US

We report on hydrophobic self-assembled monolayers (SAM) with an improved chemical and mechanical stability on both Al and Si substrates. These improvements are obtained using a relatively new molecular vapor deposition method - MVDTM, which [...]

Integrated Hierarchical Design of Microelectrofluidic Systems using SystemC

Zhang T., Chakrabarty K., Fair R.B., Cadence Design Systems, Inc., US

This paper describes the role of SystemC in developing an integrated modeling and simulatio environment for microelectrofluidic systems (MEFS). Based on the unique modeling and simulation needs for MEFS, we examine suitability of several existing [...]

System Performance Evaluation with SystemC for Two PCR Microelectrofluidic Systems

Zhang T., Chakrabarty K., Fair R.B., Cadence Design Systems, Inc., US

We present a performance comparison between two types of microfluidic systems - continuous-flow systems and droplet-based systems. The comparison based on a specific microfluidic application - a polymerase chain reaction (PCR) system. The modeling and [...]

Design of Reconfigurable Composite Microsystems Based on Hardware/Software Co-design Principles

Zhang T., Chakrabarty K., Fair R.B., Duke University, US

Custom microsystems are expensive, inflexible, and unsuitable for high-volume production. We address this problem by leveraging hardware/software co-design principles to design reconfigurable composite microsystems. We partition the system design parameters into nonreconfigurable and reconfigurable categories. [...]

Hierarchical Simulation for Microelectrofluidic System Performance Analysis

Zhang T., Dewey A., Duke University, US

With the sophisticated development of microelectro fluiidic devices and systems, system performance analysis is a key for system optimization and system re-design. Due to the increasing complexity and natural characteristics of microsystems, system performance is [...]

Towards Microelectrofluidic System (MEFS) Computing and Architecture

Dewey A., Fair R.B., Jopling J., Ding J., Zhang T., Cao F., Schreiner B., Pollack M., Duke University, US

This paper presents the rationale, design, and simulation of next-generation microelectro fluidic system computational architectures for the emerging field of bioinformatics. Current microelectro fluidic processors (e.g. biochips) have largely dedicated architectures supporting relatively specialized applications. [...]
