Inexpensive, mass-produced genes core of synthetic biology advances at UH

...technology similar to that used in making computer chips and therebyreduces cost and time factors drastically. Gao’s group estimates thatthe new technology will be about one hundred times more cost- andtime-efficient than current technologies.With this discovery, Gao and her colleagues have developed a tec...

...aboratories. Other applications include customized chips for space travel in order to monitor microbes inside spacecraft or to detect life on other planets. An obvious prerequisite for such miniaturized labs are appropriate microcompartments for the confinement of very small amounts of liquids and chemica...

Development of portable infectious disease detector

... to move around minuteamounts of liquid on silicon chips proved to be considerably moredifficult than most of the inventors had expected and the products thatthese companies have created thus far have been too expensive for thepoint-of-care diagnostics market.For their home fertility tester, Pria kept cost...

Programmable cells: Engineer turns bacteria into living computers

...uts that are more commonly associated with silicon chips than biological organisms. The new paper applies similar techniques to a large population of cells. "Here we're showing an integrated package where the cells have an ability to send messages and other cells have the ability to act on these messages,...

Study: 'homemade' gene expression technology unreliable

...riment is repeated elsewhere," Spencer said. Gene chips contain tens of thousands of tiny droplets containing a cell's whole gene sequences that are laid out on a single microscope slide by fast-moving robotic machines. Scientists determine how the expression of individual genes is turned up or down by pl...

Marine sponge yields nanoscale secrets

...ant element on the planet technologically. Silicon chips are fundamental components of computers and telecommunications devices. In combination with oxygen, silicon forms fiber optics and drives other high-tech applications. Morse explained that his research group discovered that the center of the sponge'...

Gov't Creates Gene Database of Normal Human Tissues

...cted has more than 42,000 detectors built into two chips using verified cDNA libraries upon which many other researchers currently rely. Analyzing the organ tissue with this tool allowed Khan and his team to identify 18,927 genes that constitute their database. "We found that each organ had a unique expres...

New mitochondrial DNA gene chip may be early cancer diagnosis tool

...h a newly developed DNA sequencing chip. The mtDNA chips are a promising research tool for early clinical cancer diagnosis that may be faster, easier to interpret, and provide higher throughput than other methods. A paper describing the NCI-NIST work appears in the May issue of the Journal of Molecular Dia...

Human cerebellum and cortex age in very different ways

...es with age." The researchers used data from gene chips to look at gene expression -- the degree to which various genes are turned "on" and "off" -- in five different regions of the brain's cortex. They found that in all five cortical areas, brain changes with aging were pronounced and consistent. Changes...

Customized gene chip provides rapid detection of genetic changes in children's cancer

...licated in neuroblastoma. Microarrays are silicon chips that contain tightly ordered selections of genetic material upon which sample material can be tested. When DNA bases from a sample bind to complementary sequences on the microarray, they cause fluorescent tags to shine under laser light. This is a si...

New battery technology helps stimulate nerves

... on silicon chemistry. Silicon, the stuff computer chips are made of, is one of the Earth's most abundant elements. Organosilicons are compounds composed of silicon and other natural materials. In the context of the lithium battery, West's group has been making and testing "designer silicons" that are spe...

Researchers make long DNA 'wires' for future medical and electronic devices

...iny droplet of DNA solution," Guan said. Computer chips that bridge the gap between the electronic and the biological could make detection of certain chemicals easier, and speed disease diagnosis. But first, researchers must develop technologies to mass produce DNA circuits as they produce chip circuits t...

Berkeley researchers lay groundwork for cell version of DNA chip

...s and the design of neural networks. "Just as DNA chips revolutionized genome analysis, we hope to make cell chips (self-assembled arrays of cells on a thumbnail-sized chip) using our DNA-based cell adhesion strateg...

New crop of technology reveals plant health

...n and maximise data throughput. What's more, these chips work wirelessly and contain their own batteries. They can communicate over large distances for their size, with a current range of about 10m, but again the Tyndall team hope to push their range further. "Finally, they are also looking at the potentia...
