Development of Peptide Nucleic Acid Assemblies for Application in Drug Delivery and Molecular Sensing

Butler F.N., Elibol O., Hines B.D., Reddy Jr. B., Bashir R., Bergstrom D.E., Purdue University, US

We are exploring peptide nucleic acid (PNA) assemblies as interesting scaffolds for the fabrication of nanomaterials relevant to the diagnosis and treatment of disease. The first assembly is a PNA/LNA (locked nucleic acid) duplex employed [...]

Selective Heating Characterization of Nanoplate Devices for Simultaneous Sensing of Multiple Biomolecule Species at Ultra-low Concentrations

Elibol O.H., Reddy_Jr. B., Bashir R., Purdue University, US

We propose a novel scheme for the en masse fabrication and selective functionalization of field effect silicon nanoplate devices to enable the ultrasensitive, simultaneous and label-free detection of multiple biomolecular species in real time. The [...]

DEP Particle Dynamics and the Steady Drag Assumption

Wereley S.T., Whitacre I., Bashir R., Li H.B., Purdue University, US

The interaction of fluid drag, dielectrophoretic forces, and Brownian motion on a nanoparticle's motion is studied using a microfluidic chip with interdigitated electrodes. The flow domain is a 12 micron deep by 150 micron wide [...]

Design of Piezoresistive Silicon Cantilevers with Stress Concentration Regions (SCR) for Scanning Probe Microscopy (SPM) Applications

Gupta A., Bashir R., Neudeck G.W., McElfresh M., Purdue University, US

This paper describes and evaluates the incorporation of novel Stress Concentration Region (SCR) in silicon based cantilevers to enhance piezoresistive displacement, force, and torque sensitivities. In brief, SCR is a region, on the cantilever, with [...]
