Enzyme Immobilization on magnetic nanoparticles for enhancing biocatalysis

Liu C., Institute of Process Engineering, Chinese Academy of Sciences, CN

Magnetic nanoparticles have a wide range of applications in catalysis, separation, magnetic resonance imaging and drug delivery. This talk focuses on the synthesis, functionalization and application of magnetic nanoparticles for improving biocatalysis. Great progress in [...]

Bulk-Size Transparent Gadolinium Oxide-Polymer Nanocomposites for Gamma Ray Scintillation

Chen Q., Cai W., Hajagos T., Kishpaugh D., Liu C., Cherepy N., Dooraghi A., Chatziioannou A., Payne S., Pei Q., University of California, Los Angeles, US

Heavy element loaded polymer composites have long been proposed to detect high energy X- and -rays upon scintillation. The previously reported bulk composite scintillators have achieved limited success because of the diminished light output resulting [...]

Numerical Analysis of Coupled Particle-Fluid Transport and Free-Flow Magnetic Sorting in Microfluidic Systems

Liu C., Xue X., Furlani E.P., University at Buffalo, US

Magnetic beads are increasingly used in microfluidic systems to selectively separate and sort biomaterial from a specimen for a broad range of biomedical and clinical diagnostic applications. Most theoretical studies of such systems have been [...]

Shape-Controlled Synthesis and Catalytic Behavior of Supported Platinum Nanoparticles

Liu C., Fransson M., Zhou B., Headwaters Technology Innovation LLC, US

Shape-Controlled Synthesis and Catalytic Behavior of Supported Platinum Nanoparticles Selective hydrogenation reaction is influenced by many factors, which include the presence of catalytic activators or poisons, the temperature, pressure, solvent agitation and other conditions specific [...]

Shape-Controlled Synthesis and Catalytic Behavior of Supported Platinum Nanoparticles

Liu C., Fransson M., Zhou B., Headwaters Nanokinetix Inc., US

A 5% Pt/C catalyst with ~20 nm cubic platinum particles was prepared using a traditional preparation method (i.e. precursor impregnation, calcination, and reduction) and choosing a hydrophobic solvent in the impregnation procedure. These 20 nm [...]

Lab-on-chip for the isolation and characterization of circulating tumor cells

Laureyn W., Liu C., O’Sullivan C.K., Llaudet E., Nilsson O., Drese K.S., Roeser T., Ritzi M., Hauch S., Albert W., Borgen E., Nygren A.O.H., IMEC, BE

A consortium of 7 European partners has undertaken the challenging task to develop a microfluidic system (μTAS) capable of the isolation/enrichment and consecutive RNA/DNA characterization of circulating tumor cells (CTCs), to be used as a [...]

Development of a MEMS Vertical Planar Coil Inductor

Chen J., Zou J., Liu C., Kang S-M, Agere Systems, US

This paper presents the results of the development of a vertical planar coil inductor. The planar coil inductor is first fabricated on silicon substrate and then assembled to the vertical position by using a novel [...]

Electromechanical and Microwave S-parameter Properties of a Wide Tuning Range MEMS Tunable Capacitor

Chen J., Zou J., Liu C., Kang S-M, University of Illinois, CN

We present the electromechanical and microwave properties of a novel micromachined parallel-plate tunable capacitor with a wide tuning range. Different from conventional two-parallel-plate tunable capacitors, this novel tunable capacitor consists of one suspended top plate [...]
