Gold nanoparticles cellular toxicity and recovery

Mironava T., Hadjiargyroy M., Rafailovich M.H., SUNY at Stony Brook, US

Gold nanoparticles (AuNPs) have unique electronic and chemical properties and hence are used in many applications. However, their potential health risk(s) and interactions with cells are not fully known. Most previous studies have focused determining [...]

Construction and properties of zein-based cell supports and scaffolds

Padua G.W., Wang Q., Wang Y., Wang Q., Wang Y., University of Illinois Urbana-Champaign, US

Zein, a protein abundant in corn, is capable of self-assembly and may form a variety of structural morphologies (Wang et al 2004, Wang et al 2008a). Zein micro-fibers (Figure 1.), films, and sponges (Figure 2) [...]

Chitosan Membrane in Combinations with Nanoparticles and Adriamycin as a Treatment to Inhibit Glioma Growth and Migration

Leung S.W., Gao W., Gu H., Bhushan A., Lai J.C.K., Idaho State University, US

Our previous and on-going studies indicated that U87 cells cultured on chitosan film/membrane exhibited significantly slower growth and proliferation kinetics compared to U87 cells cultured in the absence of chitosan film/membrane. Chitosan exhibits anti-microbial activities [...]

Delivery of ferritin-encapsulated gold nanoparticles on desired surfaces

Zheng B., Uenuma M., Yamashita I., Uraoka Y., Nara Institute of Science and Technology, JP

A ferritin mutant protein, which can efficiently catch gold nanoparticles of various sizes and endow gold nanoparticles a new property to adsorb to Titanium/Titanium oxide surface, was reported.

Enhancement of Osteobalstic Bone Cell Proliferation Incubated on Plasma Treated Polymers

Mahmood M., Fejleh P.M., Ishihara H., Karmakar A., UALR, US

It was determined that polyurethane polymers have the potential to be valuable biomaterials. Some major problems with this material involve its low biocompatibility and its inability to induce cellular adhesion and proliferation on its surface, [...]

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 [...]

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 [...]

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 [...]

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 [...]

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 [...]

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 [...]
