Lab on a chip
Integration will allow numerous tests to be performed on the same chip, reducing to a negligible price the cost of each individual analysis.
Lab-on-a-chip devices can also be of interest when dealing with dangerous and explosive compounds in that they contain risks by dealing with smaller volumes at a time.
In some cases, poor healthcare clinics have the drugs to treat a certain illness but lack the diagnostic tools to identify patients who should receive the drugs. Much research is being conducted on increasing the ease of use of lab-on-a-chip.
We give here some examples of applications where lab-on-a-chip shows great promises. Then, in the 90s many researchers began to explore microfluidics and tried to miniaturize biochemical operations such as PCR.
Terry at Stanford University. Nowadays researchers do not often use silicon for labs-on-a-chip, mainly because silicon is expensive, not optically transparent except for IR and requires a clean room as well as a strong knowledge of microfabrication.

All authors should have agreed to their individual contributions ahead of submission and these should accurately reflect contributions to the work. Many researchers believe that LOC technology may be the key to powerful new diagnostic instruments. Using fast optical detectors such as the Opto Reader , for example one can detect and isolate a given cell such as cancerous cell made fluorescent using antibodies with high throughput. All Reviews and Perspectives undergo rigorous peer review, in the same way as regular research papers. Lab-on-a-chip demonstrates the ability to control cells at the single-cell level while dealing with a large amount of cells in seconds. A Perspective may take the form of a personal account of research, or a critical analysis of a topic of current interest. Historically, we have explored flow synthesis and simple separations electrophoresis , we continue to study clinical diagnostics protein assays, DNA processing , while more recent trends include biomedical, materials and environmental sciences.
Examples of global LOC application[ edit ] One of the most prominent and well known LOC devices to reach the market is the at home pregnancy test kit, a device that utilizes paper-based microfluidics technology.
Using these fabrication techniques, the first real lab-on-a-chip was created in at Stanford University for gas chromatography. Regarding its core application, the ultra multiplex diagnosis, at this time we are not certain which fabrication technologies will become the standard.

Cunningham ,Lab Chip, ,13, In the case of microPCR, which is one of the most promising technologies for future high throughput diagnostics, research focuses mainly on allowing high parallelization by a multiplication of the PCR chamber, the use of digital microfluidics to perform PCR in micro-droplets and using the latest advances in molecular biology to perform simultaneous PCR in the same mix. Research on lab-on-a-chip mainly focuses on human diagnostics and DNA analysis. PDMS polydimethylsiloxane is a transparent and flexible elastomer. Lab-on-a-chip: core technologies and applications Much research has been and is being conducted on lab-on-a-chip. As mentioned above, a big motivation for development of these is that they can potentially be manufactured at very low cost. From a research point of view, the fabrication of glass labs-on-a-chip require clean rooms and researchers with a strong knowledge of microfabrication. Please refer to our general author guidelines for more information about authorship. Paper lab-on-a-chip: lab-on-a-chip devices based on paper technologies may have strong outcomes for applications requiring ultra low-costs. In developing countries, lab-on-a-chip will enable healthcare providers to open diagnostics to a wider population and to give the appropriate treatment to people who really need it without the use of rare and costly medications. Today, all the main applications of lab-on-a-chip systems have been investigated. Global challenges[ edit ] For the chips to be used in areas with limited resources, many challenges must be overcome. Supported by G. Find out more Sullied Sediments Chemicals found in household products, including toothpaste, soaps and common drugs are threatening Britain's waterways by accumulating in rivers and canals. Notes on the preparation of these articles are available from the editor, and will be provided to reviewers.
Eventually, researchers began to integrate all the required steps from sample collection to final analysis onto the same chip, showing the real potential of lab-on-a-chip technologies.
Faster response time and diagnosis: At the micrometric scale, diffusion of chemicals, flow switch and diffusion of heat is faster. This is why governments and companies are investing more and more in labs-on-a-chip since it is now clear that these technologies will change our daily lives. In the case of microPCR, which is one of the most promising technologies for future high throughput diagnostics, research focuses mainly on allowing high parallelization by a multiplication of the PCR chamber, the use of digital microfluidics to perform PCR in micro-droplets and using the latest advances in molecular biology to perform simultaneous PCR in the same mix.
