Detection of Human and Avian Flu Viruses Using Graphenated Infrared Screen

Banerjee A., Chakraborty S., Grebel H., Institution, US

Metallo-dielectric screens (IR screens) have been investigated from the visible to the THz spectral region for astronomy and remote sensing applications. These screens are made of periodic structure aim to invoke surface plasmon polariton (SPP) [...]

Selectivity study for a reagent-less and enzyme-free nanopore glucose sensor against interferences of non-glucose sugars and other substances

Chen E.T., Duh S-H, Ngatchou C., Thornton J.T., Kissinger P.T., Advanced Biomimetic Sensors, Inc., US

Accurate blood glucose monitoring is critical for diabetes patients to tightly control their diseases. For decades, blood glucose monitoring technology has relied on the use of reagents, including enzymes, mediators, and buffers. This monitoring technology [...]

Nano-plamsonics Sensing and Integration with Microfluidics for a Lab-on-chip Biosensor

Wei J.J., Rexius M., Kofke M., Wang Y., Singhal S., Waldeck D.H., CFD Research Corporation, US

Ordered arrays of nanostructures in metal films have been studied for practical miniaturization of SPR sensing and microfluidic integration. We report a nanostructure array that is designed to permit significantly enhanced Extraordinary Optical Transmission (EOT) [...]

High-throughput multiplex protein analysis for limited sample size on a single slide

Rozhok S., Ouyang K., Dixon D., Nelson M., NanoInk Inc, US

To meet the challenges of new genomic and proteomic applications, rapid and sensitive analysis of large numbers of interactions in parallel will be required. High-density microarrays are ideally suited for parallel multiplex screening of thousands [...]

Carbon Nanotube/Green Tea Composite for the Electronic Detection of Hydrogen Peroxide

Chen Y., Lee Y.D., Vedala H., Allen B.L., Star A., University of Pittsburgh, US

Single-walled carbon nanotubes (SWNTs) and their composites are ideal candidates for chemical and biological sensing application, due to their unique electronic, chemical and physical properties. Green tea, or more specifically its main antioxidant component, epigallocatechin [...]

Probing Protein-Carbohydrate Interactions using Carbon Nanotube Nanodevices for Rapid Bacterial Detection

Vedala H., Chen Y., Star A., University of Pittsburgh, US

In this work, we demonstrate novel nanoelectronics devices based on single-walled carbon nanotube field-effect transistor (NTFET) to probe the interactions between carbohydrates and their recognition proteins called lectins. These interactions are involved in a wide [...]

Development of a capillary-driven, microfluidic, nucleic acid biosensor

He F., Jin S., Dai M., Nugen S.R., University of Massachusetts, US

An ideal point-of-care device would incorporate the simplicity and reliability of a lateral flow assay with a microfluidic device. Our system consists of self-priming microfluidics with sealed conjugate pads of reagent delivery and an absorbent [...]

From Rational Design to Probe Optimization: the Role of Nanoparticle Valency in Single Cancer Cell Detection in Blood via Magnetic Relaxation
