Protein-based nanoparticles for hydrophilic coating

Kim S., Biswas A., Evans K., USDA/ARS/NCAUR, US

Cyanoacrylate nanoparticles have been studied in great detail over the past three decades with a view to their use as controlled release drug delivery materials. The mechanism of polymerization is anionic where the initiating species [...]

New biodegradable polymers based on previously unknown functional groups for drug and gene delivery

Yoo J., Graf T.A., Kuruvilla D.J., D’Mello S.R., Salem A.K., Bowden N.B., University of Iowa, US

We developed the synthesis of three new sets of polymers based on bonds between sulfur and nitrogen for applications in drug and gene delivery. These polymers were designed to slowly degrade in water at pH [...]

Separation of mixtures of fatty acids into individual components using a nanoporous membrane

Gupta A., Bowden N.B., University of Iowa, US

We recently developed the first method to separate fatty acids derived from vegetable oils using nanoporous membranes based on polydicyclopentadiene. Fatty acids were too small and too similar in size to be separated from one [...]

Growth of ZnO Nanorods in Clay Matrix to Ensure Uniform Dispersion in Drilling Fluids

Abdo J., Haneef D., Sultan Qaboos University, OM

The rheology of drilling fluids plays an important role in controlling drilling operations. The use of modern equipment and most updated technology is wasted if it is not complimented by a compatible drilling fluid. Severe [...]

Optical Trapping of Gold-Coated Liposomes

Leung S.J., Romanowski M., University of Arizona, US

We recently introduced a nanocomposite material, plasmon resonant gold-coated liposomes, to address unmet needs in area of controlled delivery. Plasmon resonant nanocapsules are created via the deposition of gold onto the surface of 100 nm [...]

Stimuli-responsive nanogels by e-beam irradiation of dilute aqueous micellar solutions: Nanogels with pH controlled LCST

Picos-Corrales L.A., Licea-Claveríe A., Arndt K.-F., Instituto Tecnologico de Tijuana, MX

Nanogels have attracted growing interest owing to their potential for applications in drug delivery systems. In this work, responsive nanogels based on amphiphilic block copolymers crosslinked in the micellar state were prepared by electron beam [...]

Synthesis, characterization and viscoelastic properties of Nanocrystalline Cellulose grafted with Poly(N-isopropylacrylamide)

Hemraz U.D., Danumah C., Lu A., Boluk Y., National Institute for Nanotechnology, University of Alberta, CA

Nanocrystalline cellulose (NCC) is a renewable, nontoxic and biodegradable nanomaterial that can be obtained by acid hydrolysis of the amorphous regions of the widely available cellulose. The relative low density, low cost, high aspect ratios, [...]

Polymer Nanomanufacturing Strategies for Multifunctional Nanomaterials

Mead J., Barry C., Wei M., Busnaina A.A., University of Massachusetts-Lowell, US

Polymeric materials offer tremendous potential for preparing functional materials using nanoscale fillers and features. For example, the use of nanolayered materials in barrier or optical applications, nanofeatured materials for hydrophobic surfaces, and patterned polymer blends [...]
