Using Scanning Thermal Microscopy Techniques for In-Situ synthesis of Carbon Nanotubes at “room temperature conditions”

Mukkisa S., Banerjee D., Texas A&M University, US

Carbon Nanotubes (CNT) were synthesized at room temperature conditions on a heated scanning probe without the use of conventional Chemical Vapor Deposition (CVD) apparatus or the process gases. The heated scanning probe is composed of [...]

Nanolithographic Patterning of Catalysts for Synthesis of Carbon Nanotubes

Gargate R.V., Banerjee D., Texas A&M University, US

Carbon nanotubes (CNT) were synthesized on specially custom designed MEMS chips under ambient conditions without requiring conventional Chemical vapor deposition(CVD) apparatus or process gases. In this approach, a layer of fullerene (C60) of 200 nm [...]

Microfabrication of 3D Structures Using Novel Thermoplastic Elastomers

Sudarsan A.P., Wang J., Ugaz V.M., Texas A&M University, US

We demonstrate the use of novel thermoplastic elastomers synthesized by dissolving readily available polystyrene–(polyethylene/ polybutylene)–polystyrene (SBS/SEBS) triblock copolymers (e.g., Kraton™ G series) in hydrocarbon oils for which the ethylene/butylene midblocks are selectively miscible. The insoluble [...]

Investigation of Volume of Fluids (VOF) Method and System Models for Design of Microfluidic Ink Delivery Apparatus for Dip Pen Nanolithography (DPN)

Banerjee D., Texas A&M University, US

DPN™ is a versatile technology that leverages Scanning Probe Microscopy for applications in biotechnology, photomask repair, molecular-electronics, nano-electronics and mask-less lithography(1). In earlier studies (2) the DPN process was augmented for biotechnology applications (genomics, proteomics) [...]

Enhanced Separation Performance in Microfabricated Electrophoresis Devices by Electric Field Induced Collection and Metering of DNA

Shaikh F.A., Ugaz V.M., Texas A&M University, US

Microfluidic technology is a key component in the development of microfabricated lab-on- a-chip systems for use in bioanalytical and biosensing applications. These devices continue to be developed to perform a variety of DNA analysis assays, [...]

Rapid DNA Amplification in Buoyancy Driven Closed Loop Microfluidic Systems

Agrawal N., Ugaz V.M., Texas A&M University, US

Buoyancy driven fluid motion, however, can also occur in closed loop geometries in response to either vertically or horizontally imposed temperature gradients. These systems offer the exciting possibility of generating unidirectional laminar flows along a [...]
