The Dispersion of Zirconia nanoparticles : ZIRCOSTAR

Takahashi K., Yao T., Kimura J., Hashimoto H., NIPPON SHOKUBAI CO., LTD., JP

1. Introduction Recently, the LCD and OLED display market demand concerning high refractive index materials increases rapidly. The required refractive index exceeds the upper limit of organic materials that can attain, therefore the research area [...]

Superparamagnetic relaxometry (SPMR) for sensitive detection of Her-2 positive tumors in mice

Paciotti G., Minser K.E., Weldon C.L., Gomez A., Karaulanov T., Hathaway H.J., Anderson W.H., Nettles C., Huber D.L., Vreeland E.C., Imagion Biosystems Inc., US

Superparamagnetic Relaxometry (SPMR) is a non-invasive technique that utilizes superconducting quantum interference device (SQUID) detectors to localize and quantify the magnetization of superparamagnetic iron oxide (Fe3O4) nanoparticles (NPs) specifically bound to cancerous tumors. In an [...]

Evaluation of the citotoxicity of TiO2 modified on Cervical Cancer line-cells- Hela

Basante M.J., Gutierrez O., UNIVERSIDAD DEL VALLE, CO

Titanium dioxide nanoparticles are increasingly being used in pharmaceuticals, cancer therapies and cosmetics due to the unique photacatalytic properties and their small sizes. The modified TiO2 a substance with potential and future uses in the [...]

Branched PEI Capped Gold Nanoparticles in Water for siRNA Delivery to Cancer Cells

Rahme K., Guo J., Biswas S., O’Driscoll C.M., Holmes J.D., Notre Dame University (Louaize), LB

Herein we describe a simple method for the synthesis of different sizes of polyethylenimine-capped gold nanoparticles (AuNPs-PEI) in water and assess their potential to deliver siRNA or other therapeutic agents to cancer cells. AuNP-PEI with [...]

Binding Studies of Histamine-imprinted Polymers Prepared using Photochemical Polymerization for facile incorporation to sensing device

Romano E.F., So R.C., Holdsworth C., Ateneo de Manila University, PH

Accurate determination of histamine (HTM) levels in food or in samples from biological origin (e.g., tissues, urine) is important for monitoring HTM-related food poisoning or pathophysiological conditions. In this study, the imprinted polymers were accessed [...]

nano-oxygen carrier for machine perfusion organ storage

Srinivas G., TDA Research Inc., US

TDA Research, Inc. (TDA) and its collaborator Southwest Research Institute (SwRI) are developing a perfusion system for the salvage and repair of trauma injured tissue. Machine perfusion is an emerging preservation modality for tissue preservation [...]

Novel fatty-acid assisted co-precipitation method for synthesis of the SrAl2O4:Eu2+, Sm3+ storage phosphor nanoparticles

Levchuk I., Römling L., Steimle M., Osvet A., Batentschuk M., Winnacker A., Brabec C.J., University of Erlangen-Nuremberg, DE

Biological and medical imaging is a key-stone for in-vivo and in-vitro monitoring necessary for basic research and for medical diagnostics. Inorganic nanoparticles have already been established as fluorescence markers due to their high stability and [...]

Synthesis of highly efficient ZnAgInS-ZnInS/ZnS quantum dots and application for down-converted LEDs

Oh J.H., Lee K.N., Lee S., Kim S., Lee K.N., Lee S., Do Y.R., Kookmin University, KR

This study introduces innovative exothermic reaction assisted synthetic method for highly efficient green emitting ZnAgInS-ZnInS/ZnS quantum dots (QDs) by simply adding excess amounts of Zn precursors (Zinc acetate dehydrate, ZAD) and application for down-converted light [...]

Photodegradation of Organic Dyes using CdSTe Quantum Dots

Aviles-Martin C., Alamo-Nole L., Pontifical Catholic University of Puerto Rico, US

The inappropriate disposal of organic dyes used in a variety of industrial applications has become the contamination source of many water sources. This environmental problem has created the need for more effective and simple methods [...]

Nano-engineering Core/Shell Quantum Dots for Ultimate Utility in Light-emission Applications

Htoon H., Hollingsworth J.A., Los Alamos National Laboratory, US

Quantum-confinement effects have been used for decades to tune semiconductor opto-electronic properties. More recently, particle-size control as the primary means for properties control has been succeeded by nanoscale hetero-structuring. In this case, the nanosized particle [...]
