Antibacterial activity and intracellular accumulation of silver nanoparticles on Escherichia coli K-12

Choi Y.J., Lee B.-T., Kim K.W., Chung K.H., Song W.K., Gwangju Institute of Science and Technology, KR

We exposed Escherichia coli K-12 to engineered silver nanoparticles (AgNPs) on to understand the antibacterial activities of AgNPs. Optical density measurement by UV-Vis was used to determine the growth inhibition of AgNPs and silver ions. [...]

Uptake and Elimination Behaviors of Polyethyleneimine (PEI)-Coated Multi-Walled Carbon Nanotubes by Eisenia Foetida and Daphnia Magna

Petersen E.J., Pinto R.A., Mai D.J., Landrum P.F., Zhang L., Huang Q., Shi X., Weber Jr W.J., National Institute of Standards and Technology, US

Hyphenated mass spectrometry (gas chromatography/mass spectrometry) techniques have been employed as one of the primary analytical tools for investigating the effects of ionizing radiation, chemical/biological carcinogens and oxygen derived free radicals on the induction and [...]

Influence of liposome size on accumulation in tumor and therapeutic efficiency of liposomal near-IR photosensitizer for PDT based on aluminum hydroxide tetra-3-phenylthiophthalocyanine

Meerovich G.A., Meerovich I.G., Meerovich G.A., Meerovich I.G., Pevgov V.G., Lukyanets E.A., Oborotova N.A., Gurevich D.G., Zorin A.A., Derkacheva V.M., Smirnova Z.S., Loschenov V.B., Vorozhtsov G.N., Baryshnikov A.Yu., A.M. Prokhorov General Physics Institute of RAS, RU

Size of nanoparticles is considered to be the one of main factors determining the efficiency of nanostructural antitumor drugs. Current work was performed to estimate the influence of liposomal size distribution on level and selectivity [...]

Compact Modeling and Circuit Impact of a Novel Frequency Dependence of Capacitance in RF MOSFETs

Sudhama C., Joardar K., Whitfield J., Zlotnicka A., Motorola SPS, US

The exploration and modeling of high-frequency MOSFET phenomena are vitally important because MOSFETs are emerging as candidates for active devices in front-end RF circuits operating at more than 1GHz [1-2]. In this work we present [...]
