Fluorescent quantum dot as model imaging probe for studying plant uptake, systemic mobility, localization in plant tissue and potential fate of ultra-small nanoparticles

Das S., Tharkur J., Tetard L., Gesquiere A., Santra S., University of Central Florida, US

Semiconductor fluorescent quantum dots (Qdots) are popularly used as bioimaging taggants in live cell imaging and spectroscopy. In recent years, Qdots taggants are emerging in agricultural applications. Studies are primarily focused on nanotoxicity of ultra-small [...]

Nanodielectrics for use in HVDC power systems and their structure-property relationships using Chemometric methods

Stevens G.C., Freebody N.A., Vaughan A.S., Perrot F., Gnosys Global, UK

There is a need to develop materials with controlled electrical resistivity, reduced space charge accumulation, higher thermal conductivity, higher dielectric strength, enhanced voltage endurance and surface discharging erosion resistance to cope with DC stresses in [...]

Thermal Transformation of Aqueous Lignin Suspension into Nanoparticle Dispersion and Its Associative Properties

Zhaoquing L., Gast J.C., Bottorff K.J., Solenis LLC, US

LIGNIN IS THE SECOND MOST ABUNDANT BIOPOLYMER. NANOPARTICLE DISPERSIONS OF LIGNIN WERE OBTAINED BY SIMPLY HEATING IN A CONTROLLED MANNER A PARTIALLY NEUTRALIZED LIGNIN SUSPENSION IN WATER. THE LIGNIN NANOPARTICLES WERE FOUND TO FORM STABLE [...]

An Integrated Biometric Platform for Evaluation of Targeted Drug Delivery

Liu Y., Thomas A., Uhl C., Wang S., He R., Lehigh University, US

In order to develop in vitro methods, which more closely resemble in vivo environments, a novel technology involving the use of microfluidic devices, which more closely mimic blood vessels has been developed. The technology has [...]

Nephrotoxicity of Dextran Functionalized Graphene Nanoparticles and Their Potential as Magnetic Imaging Contrast Agents for Renal Abnormalities

Lee S., Kanakia S., Toussaint J., Kukarni P., Chowdhury S.M., Khan S., Shroyer K., Moore W., Sitharaman B., Stony Brook University, US

Contrast-enhanced magnetic resonance angiography (MRA) employs the use of blood pool contrast agents (CA) such as gadolinium (Gd3+) complexes that allow for delayed phase arterial and venous imaging and improve the sensitivity in detecting small [...]

Enhanced Kinetics of Enzymatic Nanosensors

Breger J., Walper S., Ancona M., Stewart M., Susumu K., Medintz I., Naval Research Laboratory, US

Nanosensors employing quantum dots (QDs) and functional moieties such as enzymes are promising for diagnostics and chemical/biological threat activity. Their small size permits cell penetration and their inherent photochemical properties are well-suited for rapid, optical [...]

Oxidized Graphene Nanoribbons as a Delivery System for the Bioactive Sphingolipid Ceramide

Suhrland C., Truman J.P., Sitharaman B., Stony Brook University, US

Dysregulation of the metabolic pathways of the sphingolipid ceramide has been shown to play key roles in cancer cell proliferation and survival. Targeting these pathways with exogenous modulators of ceramide metabolism such as the short [...]

The use of Werner complexes as remarkably versatile bioconjugation reagents in the synthesis of redox repsonsive albumin nanoparticles containing camptothecin derivatives

Cavazos R.J., Morrison C.S., Lampe J.B., Nguyen D.T., Harris A.N., McFarlin B.K., Petros R.A., University of North Texas, US

Alfred Werner, the father of inorganic chemistry, received the Nobel Prize in 1913 for his pioneering work in formulating a theory to describe bonding patterns for coordination compounds. A number of complexes studied were amine [...]

Ag Nanoparticles as Low Emissivity Coating Materials for Window Glazing Applications

Gao T., Jelle B.P., Norwegian University of Science and Technology, NO

We communicate here the application of Ag nanoparticles as low-e coating materials, which may bridge the vast effort on the synthesis of metallic nanoparticles and the great potential of improving the energy feature of building [...]
