A Metallofullerene Nanoparticle Platform for Imaging and Treatment of Glioblastoma Multiforme Tumors

Dorn H.C., Zhang J., Fatouros P., Shultz M.D., Wilson J.D., Virginia Polytechnic Institute and State University, US

Glioblastoma multiforme (GBM) brain tumors occur as masses with infiltrative margins that are extremely invasive. GBMs result in a high recurrence rate with a poor prognosis for patients who are newly diagnosed with only an [...]

A sensing properties study on miniature Au/SnO2 gas sensor for hydrogen sulfide detection

Chang B-W, Ding S-J, Chen R.L.C., Hungkuang University, TW

The purpose of this study was to investigate the sensing properties for self-developed hydrogen sulfide gas sensor. In different temperature treatment and Au nano-particles doping ration, the sensitivity and selectivity of Au/SnO2 gas sensor were [...]

Sample Preparation by On-Chip Dielectrophoretic Separation and Concentration of Viable, Non-Viable and Viable but Not Culturable (VBNC) Escherichia coli

Packard M., Shusteff M., Alocilja E., Michigan State University, US

Although bacterial culture remains the gold standard for detection of viable bacteria in environmental specimens, the typical time requirement of twenty-four hours can delay and even jeopardize appropriate determination. In addition, culture is incapable of [...]

Ultralow Detection of Bio-markers using Gold Nanoshells

Patel D., Zhang G., Sun X., Gobin A.M., Keynton R.S., University of Louisville, US

The focus of this project is to improve the detection of antigen/biomarkers/viral vectors using gold nanoshells (GNS). The assay used in this project is based on aggregation of GNS in presence of antigen or viral [...]

Nanocomposites of Nanocrystalline Cellulose for Biosensors Applications

Incani V., Danumah C., Boluk Y., University of Alberta, CA

The development of composite materials is getting increased interest, as they can be a way to achieve adequate sensitivity and stability for biosensors. In this work, we describe the use of a composite material made [...]

Gold nanoparticles as a tool to detect UTI and their cytotoxic effects in DU-145 cells

Vedantam P., Tzeng J., Brown A., Podia R., Staley K., Rao A., Clemson University, US

The abstract includes a brief description of how two different kinds of E.coli can have different binding specificities and detection of such organisms with sugar functionalized nanoparticles can be used as a biodiagnostic technique.

PLGA-PEG multifunctional nanoparticles for simultaneous drug delivery and imaging by MRI and fluorescence microscopy

Fornara A., Chiavarino A., Qin J., Toprak M.S., Muhammed M., YKI, Institute for surface chemistry, SE

In recent years, a lot of effort has been put to develop smart nanocarriers for drug delivery to increase the efficacy of certain therapeutic drugs. Still the main challenge is to integrate the therapeutic function, [...]

Breath acetone monitoring by portable Si:WO3 gas sensors

Righettoni M., Tricoli A., Gass S., Schmid A., Amann A., Pratsinis S.E., ETH Zürich, CH

Breath analysis has the potential for early stage detection and monitoring of illnesses to drastically reduce the corresponding medical diagnostic costs. In particular, the detection of acetone in the human breath is promising for non-invasive [...]
