Telemedicine is rising in popularity for a number of reasons therefore it is no surprise that the Southwest Regional Telehealth Resource center is being created by the Arizona Telemedicine Program. As of right now, the Telehealth network covers Arizona, Colorado, New Mexico, Utah, and Nevada, and soon they will be a network of resource centers [...]
It is important to realize that a biochip is not a single product, but rather a family of products that form a technology platform. Many developments over the past two decades have contributed to its evolution. The very concept of a biochip was made possible by the work of Fred Sanger and Walter Gilbert, who [...]
A large amount of research and development has contributed to the rapid evolution of biochip technology. Combining semiconductor technology with molecular biology, biochips supplement electronic circuits with biological material. Composed of DNA, RNA or protein, a biochip holds these materials to the surface of a “chip”. Chips are usually composed of glass, plastic, or silicon. [...]
According to a new report titled “Protein Biochips: On the Threshold of Success”, sales in this industry are poised for enormous growth with at least 25 companies either selling protein biochips or preparing to enter the market within the next two years. Genomics technology is moving well beyond an initial emphasis on deciphering genetic code [...]
PCR, as polymerase chain reaction is known, was one step on the way to the current status of biochip technology. A Nobel-prize winning discovery, Kary Mullis’s polymerase chain reaction (PCR), first described in 1983, allowed researchers to amplify minute amounts of DNA to quantities where it could be detected by standard laboratory methods. A further [...]
Biotechnology took a dramatic turn In the 1980’s following the invention of the DNA sequencing approach in 19080 and the discovery of polymerase chain reaction (PCR) in 1983. Biochips emerged as a novel micro technology platform for analysis of bio-molecules. This has culminated in a lively biochip industry with biotechnology company Amersham at the forefront. [...]
DNA analysis has benefited from advances in bioarray technology. Bioarrays are similar to electronic memory, storing known information for comparison to unknown data for identification. They have emerged as the fastest and most efficient DNA analysis technique, giving researchers the ability to perform up to 10,000 DNA tests, and more, at one time on a [...]
In contrast to traditional hybridization assays, which utilize flexible membranes such a nitrocellulose and nylon, radioactivity, and autoradiography, microarray or biochip, assays utilize solid surfaces such as glass with fluorescent labeling and detection. Compared to the macroscopic format of filter-based assays, the miniaturized biochip format represents a fundamental revolution in biological analysis. One advantage of [...]
