Biocompatibilities of some synthetic polymers in films

Kim G., Kim H., Yoon J., Ree M., Kim G., Kim H., Pohang University of Science and Technology, KR

Materials for artificial devices require biocompatibility with the human body. Moreover, it has been well known that the implants are facilely tainted with pathogenic bacteria during surgical processes and that a few bacteria circulate in [...]

Protein binding to particle surfaces determines intracellular interaction and uptake kinetics

Ehrenberg M., McGrath J.L., University of Rochester, US

People are exposed to nanoparticles in from varying sources and in many ways. The goal of our research is to simplify this diverse problem by establishing a systematic understanding of the properties of particles that [...]

Phage-Derived Bioselective Nanovehicles for Drug and Gene Delivery

Petrenko V.A., Auburn University, US

Phage display technology rests on two fundamental concepts: combinatorial chemistry and fusion phage. We first demonstrated fusion of the major coat protein of the phage with foreign random peptides, which results in landscape phage libraries. [...]

Electrophoretic RNA Transport Through Transmembrane Carbon Nanotubes

Zimmerli U., Koumoutsakos P., ETH Zürich, CH

We study electrophoretic transport of RNA through carbon nanotubes embedded in membranes using molecular dynamics simulations. % Doped and naked carbon nanotubes are inserted into a dodecane membrane and a dimyristoylphosphatidylcholine lipid bilayer and we [...]

Favored Osteoblast Interactions with Aerosol Printed 3D Nano-to-Macro Hierarchical Architectures: The Promise of Nanocomposites as Orthopedic Prostheses

Liu H., Webster T.J., Brown University, US

Ceramic/polymer nanocomposites simulate bone in terms of its nanostructure and associated properties, thus, offering a promising new opportunity for bone regeneration in a natural way. Previous in vitro studies demonstrated that well-dispersed nanophase titania in [...]

Protons’ binding within nanometer scaled compartments of natural ionic reservoirs: Bacillus subtilis spores

Kazakov S., Bonvouloir E., Gazaryan I., Pace University, US

Dormant spores of bacteria of Bacillus genus are intriguing micrometer-scaled objects for a physico-chemical study. The most paradoxical feature of dormant spores is that, being metabolically inactive and resistant to environmental insults, they actually monitor [...]

Novel surface architectures for biomimetic lipid membranes

Reimhult E., Merz C., Ye Q., Textor M., Swiss Federal Institute of Technology (ETH Zürich ), CH

Many important biological processes occur at, via or across one of the various lipid membranes present in the cell. These include transport governed by transmembrane proteins constituting more than 50% of all drug targets of [...]

Preparation of multifuctional nanofibrous scaffold for tissue engineering

Yang X., Ogbolu K.R., Wang H., Stevens Institute of Technology, US

Multifucntional fibrous scaffolds can be produced via layer-by-layer deposition of electrospun nanofibers containing variable function. This scaffolds can be used in tissue engineering of complex structure by allowing specific controlled microenvironment for heterogeneous cell types.

Interaction of carbon nanotube material with rat skin by 21 T MRI

Sharma R., Shetty K., Liang R., Chen C-J., Florida State University, US

Carbon nanotubes are emerging as potential tools in drug delivery nanocarriers to target specific cell types and carbon cages filled with metal molecules and may improve MRI microimaging. The present paper reviews the current state [...]

Fate, Transport, and Toxicity of Nanomaterials in Drinking Water

Zhang Y., Koeneman B.A., Chen Y., Westerhoff P., Capco D.G., Crittenden J., Arizona State University, US

The objective of this research is to evaluate the potential risk of human exposure to nanomaterials in drinking water by examining three issues: 1) characteristics and stability of nanomaterials in the water environment; 2) removal [...]
