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.

Qdots as smart pH probes monitor proton flux driven by ATP synthesis and optical coder for detection various virus

Jiachang Y., Institute of Biophysics, Chinese Academy of Sciences, CN

Here we described a novel approach of CdTe quantum dots fluorescence probes to improve the detection of proton flux through F1F0-ATP by ATP synthesis. It was found that both the CdTe quantum dots (535nm, 585nm) [...]

Nitrosyl-iron Complexes as Potent Smart Nitric Oxide Biosenors: MRI imaging Techniques in Progress

Sharma R., Kwon S., Florida State University, US

Nitric oxide is a gaseous, free radical which plays a role as a diffusible intracellular second messenger. It is emerging as biosensor for monitoring myocardial ischemia and the effect of HMG-CoA reductase inhibitor statins. Presently, [...]

Qdots as smart pH probes monitor proton flux driven by ATP synthesis and optical coder for detection various virus

Zhang Y., Deng Z., Yue J., Tang F., Institute of Biophysics, Chinese Academy of Sciences, CN

The chromatophores allow self assemble with the negatively charged Qdots through electrostatic reaction. The fluorescence intensity of Qdots not only was vastly different in the solution and on the surface of chromatophores, but also for [...]

Modified Nanoparticle Films for Transmission Plasmon Biosensing

Bonroy K., Frederix F., Reekmans G., Jans H., Jans K., Jans H., Jans K., Van de Broek B., De Palma R., Borghs G., IMEC, BE

The principle of the Transmission Plasmon Biosensor is based on LSPR of metal nanoparticles attached to a transparent substrate. When the analyte of interest binds to the bioreceptors immobilized onto these nanoparticles, the absorption properties [...]
