Mutations of cypovirus polyhedrin and applications of polyhedra to protein nanocontainers

Ohtsuka Y., Nakai D., Coulibaly F., Chiu E., Metcalf P., Mori H., Kyoto Institute of Technology, JP

Cypoviruses, a member of the family Reoviridae, are one group of insect virus that produce micrometer-sized protein crystals called cytoplasmic polyhedra. Many virus particles are occluded in polyhedra to protect them against extracellular environment. Recently [...]

Agarose coating improves protein stability during sustained release

De Rosa E., Yadzi I., Liu X., Ferrari M., Tasciotti E., UT HSC Houston, US

The advances in drug-delivery systems over recent decades highly improved the effectiviness of drug administration. Biocompatible, biodegradable porous silicon microparticles stable can be modified to provide controlled release and enhanced stability of the loaded/encapsulated bioactive [...]

Optimization of preparation conditions for size-controlled solid lipid nanoparticles

Choi K-O., Jung J., Ryu J., Che J., Ko S., Sejong university, KP

This study is to prepare solid lipid nanoparticles, with target sizes at 100, 500 and 1000 nm. Nanocrystallization method was applied to prepare solid lipid nanoparticles using beef tallow, hydrogenated soybean oil and hydrogenated palm [...]

Mammalian cells in nanocapsules:fiber production in co-flowing ambient liquid stream

Sharma A., Sharma R., Sharma A., Sharma R., Innovations and Solutions Inc., US

Mammalian cell-enclosed in nanocapsules have been investigated as devices for bioproduction, cell therapy and stem cell research. Reduction in the diameter of the vehicles is an important issue as it induces beneficial effects such as [...]

Mechanochemical and Sonochemical Synthesis of Bio Based Nanoparticles

Hassan T.A., Rangari V.K., Fallon V., Farooq Y., Jeelani S., Tuskegee University, US

•The size reduction process for seashell particles can be efficiently used for the production of Aragonite CaCO3 bio nanoparticles. A mechanichemical and sonochemical method was developed to synthesize bio calcium carbonate nanoparticles.

Hybrid Poly(L-Lactide) (PLA) Nanofibers Incorporating POSS-Modified Multiwalled Carbon Nanotubes Prepared by Electrospinning

Kim B.S., Kim I.S., Kim K-O, Kim Y-A, Jeong I., Kim B.S., Kim I.S., Kim K-O, Kim Y-A, Kim B.S., Kim I.S., Kim K-O, Kim Y-A, Kim B.S., Kim I.S., Kim K-O, Kim Y-A, Shinshu University, JP

Organic–inorganic hybrid composites have attracted considerable attention because of their distinctive physical and chemical properties. Specifically, the multiwalled carbon nanotube (MWNT)-polymer composites among them has expected when uniform dispersion of the MWNTs in the polymer [...]

Molecular imprinted nanoPolymer nanomaterials: application in biomolecule recognition

Sharma A., Sharma R., Sharma A., Sharma R., Innovations and Solutions Inc., US

Molecular imprinting has proved to be an effective technique for generating specific recognition sites in synthetic nanopolymers. These sites are tailor-made in situ by copolymerization of functional monomers and cross-linked around the template molecules. The [...]

Ultra-Structural Analysis of the Interaction of Carboxylated Multi-Walled Carbon Nanotubes with Human Blood Platelets

Lacerda S.H., Semberova. J., Holada. K., Simakova O., Gelderman-Fuhrmann M.P., Simak J., Simakova O., FDA, US

Carbon nanotubes (CNTs) are a promising new class of materials with many potential biomedical applications. CNTs have profound impact on the development of diagnostic biosensors, drug delivery nanosystems, imaging nanoprobes for intravascular use or other [...]

Effect of cytosol on the dynamic behaviours of microtubules

Wang C.Y., Li C.F., Adhikari S., Swansea University, UK

The cytosol effect on the dynamic behaviours of microtubules (MTs)is examined based on a newly developed shell-Stokes flow model. The phonon dispersion relations are predicted and the damping effect of cytosol is quantifies. Three differernt [...]

New Multimodal Iron Oxide Nanoparticles as Nanotools for Cancer

Benyettou F., Chebbi I., Lalatonne Y., Sainte-Catherine O., Di Benedetto M., Lecouvey M., Seksek O., Motte L., Université Paris 13, FR

The goal of this project is to elaborate new multifunctional magnetic nanovectors to vectorize biological interest molecules for therapy and diagnostic applications. Indeed, iron oxide nanoparticles, tanks to their magnetic properties, are used as contrast [...]
