An Improved Microgripper for Cell Manipulation

There is a growing need for individual cell manipulation in a wide range of research applications including stem cell sorting, gene and molecular delivery, cellular diagnostics, and single cell-based assays. When compared with data-averaging over a cell population, direct physical cell manipulation offers the researcher much more precise selection and understanding of cell properties.

Sony create thinnest screen yet

A leading electronics manufacturer has managed to make an OLED screen that is just one-fifth of a millimetre thick.

A leading electronics manufacturer has managed to make an OLED screen that is just one-fifth of a millimetre thick.

Sony's prototype OLED (organic light emitting diode) screen was on show at last week's Display 2008 exhibition in Tokyo and ranks as the thinnest yet developed.

The prototype 3.5in panel, which has QVGA resolution (320 pixels by 240 pixels), started out as a normal OLED screen, but the glass substrate on which it was made was ground down to reduce the thickness to just 0.2mm.

Typically OLED screens are about a millimetre or two thick. This is because OLED pixels emit their own light and so do not require additional illumination. It is this illumination that adds to the thickness of LCD (liquid crystal display) panels.

Many display makers are developing OLED technology as their thinness means panels consume less power than LCDs, handle fast-moving images better and offer good colour reproduction.

At the end of last year Sony began sales of the world's first OLED television. The XEL-1 is based on an 11in panel that is 1.4mm thick. Most of the set's electronics are in the base, so the screen thickens to only 3mm with a plastic case around the screen.
