LoC And LoPCB Technology Will Be In The Diagnosis Of The New Champions

 Recently developed a test kit adopted based on portable lab on a chip (lab - on - chip, hereinafter referred to as the LoC ) platform technology, a test can detect, identify and distinguish MERS - CoV, SARS - CoV and COVID - 2019 virus, just 2 hours and LoC technology may be to develop powerful new diagnostic instruments and instant key test equipment.

  LOC can be used in biomedical research and medical micro-devices, focusing on mechanical components and micro-manufacturing technologies, including disease detection, chemical surveillance and drug delivery, with great potential for large-scale commercialization

  The basic building blocks of LOC：
（1）Electrophoresis: separation column

Electrophoresis：under the action of an electric field, a similar mixture of molecules flows to an electrode of a liquid on a different medium to separate out the macromolecules, used for separating and purifying biological molecules

（2）Microfluidics： channels, valves-pumps and mixers

The flow in a microchannel is a layered flow that allows selective treatment of cells in microchannels, arrays, or biochemical reactions

（3）Biochemical detectors and sensors

（4）Microfluidic chip

  Materials:

Silicon-based materials

Glass based materials

Polymer /PCB base

  Conclusion:

In fact, in March 2020, the United States food and drug administration (FDA) to 6 companies issued an emergency use authorization, (EUA), The six companies are:Roche Holding AG,Thermo Fisher Scientific，Hologic Laboratories，Quidel and allow them to use the SARS - CoV - 2 EUA test method, as the fastest get molecular PoC will be used in the detection of coronavirus (COVID - 19).
