Surface Chemistry of Metal Oxide Nanoparticles and Attachment of Metal Nanoclusters: Sensor, Optoelectronic, and Catalytic Applications

Whitten J.E., University of Massachusetts-Lowell, US

Metal oxide nanoparticles are surprisingly reactive, and some undergo changes in color or in their photoluminescence (PL) spectra upon reaction. In the latter case, visible emission arises from electron decay from surface related states, and [...]

Magnetic Nanoparticles for Radio Frequency Hyperthermia: Preparation and Surface Functionalization Effects on Cellular Uptake

Gilliland III S.E., Carpenter E.E., Shultz M.D., McGuire VA Medical Center, US

Iron oxide nanoparticles have received sustained interest for biomedical applications as synthetic approaches are continually developed for precise control of nanoparticle properties. This work presents an investigation of parameters in the benzyl alcohol synthesis of [...]

Influence of Polyvinyl Alcohol (PVA) on Morphology and Encapsulation Efficiency of Polylactic Acid-Polyethylene Glycol (PLA-PEG) copolymer based Nanoparticle’s

Dixit S., Davis M.D., Singh S.R., Dennis V.A., Alabama State University, US

Polyvinyl alcohol is the most commonly used emulsifier in the formulation of NPs. Provides non-aggregating, emulsifying and adhesive properties to NPs and an interconnected network with the polymer at the interface which ultimately can affect [...]

Hybrid biosensor for the early diagnosis of breast cancer

Cho K., Chong S., Chong S., Park E., Lee J-H., Luminescent MD, LLC, US

A cost-effective and novel hybrid biosensor using the combination of antibody and DNA aptamer was developed for the early diagnosis of breast cancer. 1,1’-oxalyldiimidazle chemiluminescence (ODI-CL) was applied as a detector of the hybrid biosensor. [...]

Breast cancer diagnosis system using the combination of carcinoembryonic antigen aptamer, horseradish peroxidase-mimic hemin, and graphene sheet

Chong S., Cho K., Chong S., Khang H.J., Lee J-H., Lee S-Y, Kim Y.T., Lee J-H., Lee S-Y, Luminescent MD, LLC, US

In order to early diagnose breast cancer with the rapid quantification of carcinoembryonic antigen (CEA) in human serum, highly sensitive DNA aptasensor with 1,1-oxalyldiimidazole chemiluminescence (ODI-CL) detection was developed using the combination of CEA aptamer, [...]

Insulator oxide film formation with acid catalyzed hydrolysis of alkoxides in supercritical fluid carbon dioxide

Wang J-S., Wai C.M., Brown G.J., Apt S.D., Campo A.M., Landis G.R., Air Force Research Laboratory, US

Insulator oxide films can be produced by hydrolysis of metal alkoxide precursors in the presence of an acid catalyst in supercritical fluid carbon dioxide(sc-CO2). In this study, a new process has been developed to cover [...]

Quantum Dot Applications in LCD Displays

Nelson E.W., McDaniel D.J., L. Eckert K, 3M Display Materials and Systems Division, US

Quantum Dot (QD) technology offers the promise of efficient and relatively inexpensive liquid crystal displays (LCDs) with a large color gamut. Quantum dot displays now offer a variety of high color performance devices for applications [...]

Visible and Infrared emission from Erbium Oxide nanoparticle, for optical and biomedical applications

Maqbool M., Ball State University, US

Light emitting nanoparticles are getting special attention due to their use in optical technology and biomedical applications. The present work reports light emission from Erbium Oxide nanoparticles. The nanoparticles, with 43 nm diameter, were obtained [...]

Multifunctional Nanostructures and Nanoarchitectures

Hunyadi Murph S.E., Savannah River National Laboratory, US

The development of functional nanomaterials with multi-detection modalities opens up new avenues for creating multi-purpose technologies for many applications. The “ideal” nanoparticle would combine multiple detection modalities (magnetic, plasmonic, elastic or inelastic light scattering, fluorescence, [...]

Hydrothermal Synthesis of Silver Nanowires and Application as Transparent Conductive Materials

George A.L., McGough P.T., Lunn J.D., Wang W., Kuo T.-C., Todd C.C., Goss J.M., Collins R.M., Malek A., Calverley E.M., The Dow Chemical Company, US

A scalable hydrothermal synthesis for silver nanowires has been developed. The new synthetic route is expected to be compatible with industrially available reactor systems and offer environmental and safety advantages due to use of aqueous [...]
