Cytotoxicity of bare and PEGylated silica nanoparticles as potential gene-delivery vectors

Yagüe C., Saldaña L., Martin F., Arruebo M., Vilaboa N., Santamaria J., Universidad fe Zaragoza, ES

Silica and other inorganic carriers are one of the major groups used to transport drugs and bioactive molecules into cells. The others are viral carriers, organic cationic compounds and recombinant proteins. The use of mesoporous [...]

A Needs-based Assessment of Measurements for Nanotechnology / Environmental Health and Safety

Allocca C.M., Campbell T., National Institute of Standards and Technology, US

The National Institute of Standards and Technology (NIST) is engaged in a continuing needs-based assessment of the state of the United States Measurement System (USMS). The USMS assessment addresses innovation-limiting measurement needs in three ways: [...]

Gold nanoparticle-based miniaturized NSET Probe for rapid and ultra-sensitive detection of toxic metals in soil, water and fish

Ray A., Ray P.C., Darbha G.K., Ray A., Ray P.C., Jackson State University, US

Contamination of the environment with toxic metals like mercury and arsenic have been an important concern throughout the world for decades. Human exposure to high Hg or As levels can harm the brain, heart, kidneys, [...]

Modulation of g-Irradiation Induced ROS Responses by Engineered Fullerenes in Human Epidermal Keratinocytes

Gao J., Wang H.-L., Shreve A.P., Iyer R., Los Alamos National Laboratory, US

High-dose ionizing irradiations can cause acute tissue and organ damage, especially severe cutaneous lesions. These cutaneous injuries often result in further complications and incur high mortality. Therefore, it is critical to develop effective therapeutic approaches [...]

Nanotechnology and the Water Market: Applications and Health Effects

Mowat F.S., Tsuji J., Exponent, US

Nanotechnology has an enormous potential for creating cost-effective, simple, and efficient tools for addressing water supply challenges, while preventing the creation of potentially toxic by-products. Applications include water disinfection and filtration, real-time and remote monitoring, [...]

Nanotechnology and the Global Poor: United States Policy and International Collaborations

Rodrigues R., Sandler R., Kay W.D., Lodwick T., Northeastern University, US

Nanotechnology and nanomanufacturing have tremendous potential for benefiting the global poor—the approximately 2.7 billion people in the world that live on less that 2 dollars per day (purchasing power parity). For example, nanotechnologies may help [...]

An integrated NMR/nanosensor system for sensitive detection of environmental toxins and harmful microbes

Perez J.M., Fries D.P., Hickman J.J., University of Central Florida, US

The use of nanoparticles and NMR detection technologies has lead to significant improvements in sensitivity. Nanoparticles have many useful optical and electronic properties derived from their small size. When coupled to affinity ligands, these materials [...]

Nano-Catalysts and Colloidal Suspensions of Carbo-Iron for Environmental Application

Mackenzie K., Hildebrand H., Kopinke F.-D., Helmholtz Centre for Environmental Research - UFZ, DE

The presentation contains two innovative applications of nano-sized materials for environmental application: 1) Pd catalysts for wastewater treatment. The new ferromagnetic nano-sized Pd catalysts have proved effective for selective dechlorination of industrial wastewater. Extraction by [...]

Aided Transport of Nano-Iron in Clay Soils Using Direct Electric Field

Hannum L., Pamukcu S., Lehigh University, US

The influence of direct current electric fields on the possible electrokinetic delivery of a nano-iron slurry in clay for the purpose of fast and effective remediation of soil contaminants has been tested. Nano-iron can be [...]
