Gold Nanorods Induce Innate Immune Response and Reduce Respiratory Syncytial Virus Replication

Bawage S., Tiwari P., Singh A., Singh S., Dixit S., Pillai S., Dennis V., Singh A., Singh S., Alabama State University, US

Metallic nanoparticles (MNPs) have been used for diverse applications like sensing molecules, diagnosis of cancer, delivery of drugs and vaccines. Among the various MNPs, the gold nanorods (GNR) have been commonly used for such diagnosis [...]

Peptide Functionalized Gold and Silver Nanoparticles Inhibit Respiratory Syncytial Virus (RSV) In Vitro

Baganizi D.R., Bawage S., Singh A., Singh S.R., Tiwari P., Dennis V.A., Singh A., Singh S.R., Alabama State University, US

Human respiratory syncytial virus (RSV) is a major cause of severe upper and lower respiratory tract infections in infants, and in high-risk adults. Currently, there is no vaccine and the available therapeutic agents have limited [...]

Experimental study of sensitivity enhancement in SPR biosensors by use of zinc oxide intermediary layers

Chiu N.-F., Singh A., Nelson-Fitzpatrick N., Dutt S., Evoy S., Lin C-W, National Taiwan Normal University, TW

We report a novel design for the intermediary layer of surface plasmon resonance (SPR) devices that use high refractive index and high-transmittance zinc oxide (ZnO) dielectric layers to enhance the signal quality and improve the [...]

Chromatographic Purification of Bacteriophages for Improved Surface Capture of Bacteria – Towards a General Approach

Naidoo R., Singh A., Glass N., Arya S., Evoy S., National Institute for Nanotechnology, University of Alberta, CA

We report in this study the largest surface capture density of E Coli using the wild-type T4 bacteriophage; whereby higher surface capture density can enable higher sensitivities for surface-based biosensors. This was possible due to [...]

SiCN nanomechanical resonators for array-based biosensor applications

Guthy C., Singh A., Tanha J., Evoy S., University of Alberta, CA

Rapid, sensitive and inexpensive analysis of biological molecules is of great importance to many biomedical applications, such as disease detection and monitoring, drug discovery, detection of pathogens, etc. Mechanical resonators have been demonstrated as highly [...]

Enhanced Biodegradation of 2,3,4,5,6-pentachlorocyclohexan-1-ol — a b-HCH Metabolite — in the Presence of a and g-HCH Isomers by Pseudomonas aeruginosa ITRC-5

Singh A., Kumar A., Misra K., Rice University, US

Chlorinated insecticide hexachlorocyclohexane (HCH), which is still used in many countries in agriculture and forestry, leads to environmental problems. HCH consists of a mixture of four isomers: a-, b-, g-, and d. Efforts have been [...]

Isolation and Characterization of Benzene Degrading Bacteria from Gasoline Contaminated Water

Singh A., Sar P., Bennett G., Rice University, US

The BTEX (benzene, toluene, ethylbenzene, and xylene)compounds are hydrocarbon pollutants that are considered as significant threat to the health and environment. Among BTEX, benzene is of major concern, because it is soluble, mobile, toxic, carcinogenic [...]

Improvement of Hydrogen Production by Immobilized Rhodopseudomonas palustris CGA009 Using Reverse Micelles as Microreactor

Singh A., Misra K., Rice University, US

Within the process of photobiological hydrogen production, purple non-sulfur (PNS) bacteria are an interesting subject of study because of their high substrate conversion efficiencies and their capability of using a wide variety of substrates either [...]
