Biochips Seminar pdf Report and ppt

For details about other array technologies, see Antibody microarray. Effectively, it is used as a kind of? The biochip is inserted into the subject with a hypodermic syringe.

It is a small capsule, the smallest measuring 11 mm in length and 2 mm in diameter, about the size of an uncooked grain of rice. Like a computer chip that can perform millions of mathematical operation in one second, a biochip can perform thousands of biological operations, such as decoding genes, in a few bkochips.

One of the first portable, chemistry-based biochis was the glass pH electrodeinvented in by Hughes.

Introduction to Chemical and Biological Sensors, pp. A non-coordinate based encoding scheme must be used to identify each sensor. This approach is used chiefly to map or “encode” the coordinate of each sensor to its function.


The actual sensing component or “chip” is just one piece of a complete analysis system. But there is a flip side to this! A genetic biochip is designed to? Latest Seminar Bochips for Engineering Students.

The unique ID number is “etched” or encoded blochips a laser onto the seminad of the microchip before assembly. Retrieved from ” swminar As noted above, most microarrays consist of a Cartesian grid of sensors. After assembly, the capsule is hermetically air-tight sealed, so no bodily fluids can touch the electronics inside.

Because the passive contains no battery, or nothing to wear out, it has a very long life up to 99 years, and no maintenance. A specifically designed microscope can determine where the sample hybridized with DNA strands in the seminarr. Breathalyzer Carbon dioxide sensor Carbon monoxide detector Catalytic bead sensor Chemical field-effect transistor Electrochemical gas sensor Electrolyte—insulator—semiconductor sensor Electronic nose Fluorescent chloride sensors Holographic sensor Hydrocarbon dew point analyzer Hydrogen sensor Hydrogen sulfide sensor Infrared point sensor Ion selective electrode Microwave chemistry sensor Nitrogen oxide sensor Nondispersive infrared sensor Olfactometer Optode Oxygen sensor Pellistor pH glass electrode Potentiometric sensor Redox electrode Smoke detector Zinc oxide nanorod sensor.

One of the first commercial biochips was introduced by Affymetrix. These arrays must be made using a serial process i. The communication between biochip and reader is via low-frequency radio waves.

The microchip is described as a sort of? The fabrication of microarrays is non-trivial and is a major economic and technological hurdle that may ultimately decide the success of future biochip platforms.


The biochip-transponder consists of four parts; computer microchip, bjochips coil, capacitor and the glass capsule. Anyway, such implants have already experimented with.

In dogs and cats, the biochip is usually injected behind the neck between the shoulder blades. The capsule is made of biocompatible material such as soda lime glass. In this approach, large batches of identical sensors can be produced; sensors from each batch are then combined and assembled into an array.

Secondly in Hood and co-workers devised a method to label DNA molecules with fluorescent tags instead of radiolabels, [7] thus enabling hybridization experiments to be observed optically. The storage capacity of the current microchips is limited, capable of storing only a single ID number.

The reader can include a RS port to attach a computer. A biochip is a collection of miniaturized test sites micro arrays arranged on a solid substrate that permits many tests to be performed at the same time in order to get higher throughput and speed.
