Application of insect virus polyhedra to protein nanocontainers

Mori H., Ijiri H., Kotani E., Kyoto Institute of Technology, JP

Certain insect viruses encode a protein called polyhedrin that forms polyhedric crystals, or polyhedra, within an infected cell. The virus particles, or virions, are protected within these polyhedra and can remain infectious for years outside [...]

Multilayer BioDerivatized Nanoparticle Composites by Electric Field Directed Self-Assembly

Heller M.J., Haiso A.P., University of California San Diego, US

An electronic microarray has been used to carry out directed self-assembly of higher order 3D structures from biotin/streptavidin, DNA and enzyme derivatized nanoparticles. Structures with up to fifty layers of alternating biotin and streptavidin, DNA [...]

Structuring Membrane Proteins as Tools in Material Science

Mille C., Corkery R.W., YKI, Institure for Surface Chemistry, SE

Two membrane proteins derived from yeast, Yop1p and Rtn1p, have been engineered, heterogeneously expressed and purified. Both proteins are membrane spanning and can be found in all eukaryotes in which they are used for structural [...]

NANOCYTES-Technology – Biomimetic nanoparticles for molecular recognition by molecular imprinting

Schreiber T., Niedergall K., Wojciukiewicz D., Gose T., Gruber-Traub C., Weber A., Hirth T., Tovar G.E.M., University of Stuttgart & Fraunhofer Gesellschaft, DE

Communication of living systems is done by molecular recognition. This central principle of the living world is performed at the contact sites of different objects such as single macromolecules or highly complex supramolecular assemblies as [...]

The Collaboratory for Structural Nanobiology

Cachau R., Gonzalez-Ibanez A.M., Sandoval and C., Gonzalez-Nilo F., Universidad de Talca, CL

Manufactured nanobiomaterials exploit the unusual properties of nanomaterials to develop new forms of intervention in biological systems. Nanobiotechnology is the field of science focused on the design, synthesis, characterization and application of nanomaterials and nanodevices [...]

Nano-hydroxyapatite and/or nano-silk fibroin as bone graft materials

SG Kim, Gangneung-Wonju National University, KR

Electrospunned silk fibroin has been considered as scaffold for tissue engineering. Particularly, it has been used for bone regeneration with nano-hydroxyapatite (nHA). Though some papers showed successful results of bone regeneration in nHA and electrospunned [...]

Carbon Nanotube-Collagen Scaffolds for Mesenchymal Stem Cells’ Differentiation: Changes in Alkaline Phosphatase Expression, Meneralizaton, and Energy Content

Bakture R., Kwon S., Sharma A., Sharma R., Sharma A., Sharma R., Utah State University, US

The applications of carbon nanotubes (CNTs) have tremendous potentials for them as substrates of cell cultures, drug delivery systems, and medical implantable materials. We characterized the energy simulations of different CNT-composite materials with the use [...]

Size of the Pores Created by an Electric Pulse: Microsecond vs Millisecond Pulses

Saulis G., Saule R., Vytautas Magnus University, LT

Modeling studies have revealed that the pulse of nanosecond-duration should create smaller pores than the pulse of micro-millisecond duration. It can be expected, that similar differences should also exist between the pore populations created by [...]

Immobilization of bioactive growth factors into cubic proteinous microcrystals (cypovirus polyhedra) and control of cell proliferation and differentiation

Mori H., Kyoto Institute of Technology, JP

Certain insect viruses produce stable infectious microcrystals called polyhedra which function to protect the virus after the death of infected larvae. Polyhedra form within infected cells and contain numerous virus particles embedded in a crystalline [...]

A Study of Inorganic-Polymer Hybrid Films for Various Surface Functionalization

Park B-S., Lui Z., Jin H.S., Yang S.-Y., Chungnam National University, KR

The PEM coatings were applied on magnetic particles and the deposited films were examined by zeta-potential analysis and fluorescence microscope. Additionally, we utilized layer-by-layer deposition method to modify the surface of the micro-channel of the [...]
