Novel Approach using SWCNT as a Mechanism of Toxicity on Fungal and Bacterial Cells

Chaves J.S., Chaves S.J., Chaves J.S., Chaves S.J., Instituto Tecnologico de Costa Rica, CR

The overall goal of this project was to characterize the potential use of SWNTs as an effective alternative to present antimicrobial agents in dealing with drug-resistance. In this study, we look at possible mechanisms to [...]

Cell damage by energy saving light bulbs

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

The growing concern regarding green house gas emissions during power generation has increased awareness regarding energy conservation. Next to transportation, lighting is one of the major sources of energy consumption. Compact fluoresce light bulbs (CFL) [...]

Dielectrophoresis and Comsol Simulation of Cell Entrapment At Electrodes

Padmaraj D., Zagozdzon-Wosik W., Pande R., Miller J.H., Xie L-M, Wosik J., Zagozdzon-Wosik W., University of Houston, US

Dielectric properties of biological samples change with frequency of the interrogating electric field therefore can be used to obtain information about structures and various kinetic as well as bio-physical and –chemical processes in the cells. [...]

Impact of CNT Ingestion on in Vitro Cells

Mangir T., Chaves J., Chaves S., Chaves J., Chaves S., CSULB, US

In this paper we will describe our results of CNT ingestion in in vitro cell cultures. We will present AFM pictures of the observed impact of CNT on cell growth. We will describe the bio-nano [...]

Specific device for cells sampling

Cosnier M.L., Martin F., Ratel D., Berger F., Caillat P., Commissariat à l’Energie Atomique, FR

We developed a miniaturized biopsy tool for harvesting molecules of interest in delicate areas such as brain. This tool permits harvesting of intact cells permitting genomic analysis on these cells. The sampling tool is manufactured [...]

Fluorescence of Water-Soluble Fullerenes in Biological Systems

Lin S., Jones D.X., Mount A.S., Ke P.C., Clemson University, US

The chemical and photophysical properties of fullerenes have been studied over the past two decades yet the biological applications of these nanoparticles remain limited. The major hurdle of integrating fullerenes with biological systems is their [...]

Microfluidic Cell Culture System for Live Cell Imaging

Powell M.J., Higashi L.K., Cabasug A.A., Giffin S.M., Alley R.K., Nanopoint Inc., US

Nanopoint has developed a novel micro-fabricated live cell containment device called cellTRAYTM designed specifically for imaging live cells. The device enables the precise containment of cells in an optical glass substrate, the size of a [...]

Comparison of the Efficiency of Different Methods for the Lysis of Cells in Lab-on-Chip Systems

Drese K., von Germar F., Roesser T., Hansen-Hagge T., Bullema J., Bolt P., TNO Science and Industry, NL

Many diagnostic or analytical tasks are based on detection of specific amplificates of DNA or RNA. Lab-on-Chip systems are developed for such tests because often only small sample volumes and analyte concentrations are available. A [...]

Noise-Differential Based Detection of Cells on a Microelectronic Sensor/Actuator Array

Manaresi N., Lanzetta F., Romani A., Medoro G., Guerrieri R., Silicon Biosystems spa, IT

We present a new method to count cells on a microelectonic lab-on-a-chip integrating an array of Dielectrophoretic (DEP) cages and embedded optical sensors. Cells are trapped by DEP cages above photodiodes measuring the optical near [...]

Labeling of Cells with Silver and Gold Host-Guest Nanocomposites

Balogh L.P., Lesniak W., Sinani V.A., Bielinska A.U., Sun K., Nair B.M., Waite E., Kariapper M.S.T., Khan M.K., Roswell Park Cancer Institute, US

Nanocomposites combine the properties of nano-sized inorganic guest atoms/molecules with their nanoscopic size polymer host. We have synthesized water-soluble, biocompatible, fluorescent, and stable nanocomposites with regulated surface charge and controlled size for cell labeling studies. [...]
