We have constructed two four-jet-tangential micro-mixers, one from stainless-steel to study reactions in a freeze-quench setup, instrumental-dead-time 60µs and one from glass allowing optical studies. Both mixers contain 70µm channels ending in premixing-chamber. After the premixing-chamber, the fluids enter a mixing-chamber and leaves at an orifice travelling further as a free jet, mixing-time 200 ns, jet flow 200 m/s, pressure 400 bar.

The EU chemical policy REACH, effective on June 2007, regulates the registration, evaluation and authorization of chemicals. Investigations on the effects of neurotoxic and developmental-neurotoxic substances are required by European and US-American test guidelines. However, at the moment these tests are based on animal experiments contradicting society claims to abolish animal experiments and to implement the 3R-principle. The resulting problem is… How to pair REACH and the 3Rs?

The Regulated Gas Medium with a Set of Nanoparticles Generated by the Solid Fuel Composition as a Method for Producing Ecovegetables
Alexandre V. Vakhrouchev and Valery B. Golubchikov, Izhevsk State University, Ltd. “Nord”

New biotechnology involving nanoparticles for the production of ecologically pure vegetables in greenhouses has described. The main feature of the method is the generation of a special controlled gas medium containing nanoparticles of the main macro- and microelements, which freely penetrate into the foliage and stems of crops providing their metabolic activity. The source of the gas medium is the products of self-spreading high-temperature synthesis.

Gold Coated Magnetic Nanoparticles for Specific Separation and Detection of Oligonucleotide Sequences and Proteins
Pedro Quaresma, Ricardo Franco, Pedro Baptista, Patricia Carvalho and Eulalia Pereira, Universidade Nova de Lisboa, Universidade do Porto and Universidade Techica de Lisboa

Monodisperse magnetic nanoparticles were produced and subsequently coated with a gold layer by the reduction at surface of a gold precursor in order to develop an integrated detection and “gene fishing” system. Functionalization of the nanoparticles could allow the application of this system to a variety of biomolecules.

Intravenous Geletin Nanoparticulate Formation of Vincristine Sulfate: Preparation, Characterisation and Release Studies
Akanksha Chauhan, V.S Shenoy and R.S.R Murthy, The Maharaja University of Baroda

Gelatin could be used as a carrier to prepare nanoparticles with considerable entrapment of Vincristine sulfate. The prepair nanoparticles could release over a period of time. The in vitro release studies have been encouraging and a possible reduction of toxicities of Vincristine sulfate would be expected on further in vivo studies.

A High Content Primary Screening Assay Identifying Multiple Protein Targets in a Cell Using Quantum Dots
Christopher Lupton, Dick Ornberg, Marcel Bruchez and Paul Wylie, TTP Labtech

The development of multiplexing capabilities and high content readouts reporting individual cellular measurements enables assessment of biological variability on a single cell basis. A multiplexed high content screening (HCS) assay allows additional information to be gained from a single assay.
