The development of technology in the medical world is very rapidly developing. One of them is Microfluidic Chip (Mchip), a technology created by Samuel Sia, a Professor from Colombia University, New York. He developed an HIV detection device with a production cost of only US $ 1 per unit and could provide accurate results, which is close to 100%.
Some other advantages of this tool include:
- Fast and accurate Mchip has gone through a series of trials in Kigali, Rwanda. The accuracy of the tests reaches 95% for HIV, and 76% for syphilis. The technology of this Mchip only requires a few finger touches to diagnose certain patients in just minutes. When compared with a blood test at a doctor, the results may come out a day, a week, or even a month later. Of course this takes a long time and can give a burden to one’s mind. With this tool, the test results can be found in just 15 minutes.
- Easy to carry and use The purpose of this design is to miniaturize the complex blood tests in the laboratory into something that can be held in hand with only the size of a credit card. Thus, people can do themselves take a drop of blood by making a puncture on the finger, then attach it to the device. Wait for about 15 minutes to get results.
- Mchip Principles for Detection of HIV-1 Mchip is a technology that can be used effectively as an HIV-1 detection test. The components of Mchip consist of 10 detector zones which are used as a space to test specimen samples and see the results of HIV-1 antibiotic test, specimen tube as an area for flowing test specimens into the detector, silver liquid as a specimen binder and provide contrast color changes to the test results and gold naoparticles as additional components in detecting HIV-1 antibodies.
Mchip technology is developed based on the ELISA principle, which uses specimens in the form of oral fluid or the patient’s blood plasma. The principle of the Mchip application is in detecting HIV-1 antibodies by instructing users to place test specimens in the form of blood serum or oral cavity and inserting it into a specimen sample tube, so the test sample flows into the detector zone that has been labeled with antibodies to HIV-1. The antibody antigen bond that occurs in the detector zone causes a color change reaction that can only be seen using the Mchip techno reader.
The test results are positive, if bluish color lines appear on one or more detector zones. If there is no change in bluish color line (only found silver lines) in the detector zone, the results are negative. The availability of this tool in Indonesia may be accessible in the near future.
That’s a little explanation about Mchip as an accurate and fast detection of HIV / AIDS. May be useful for you all.
