composition
Microcidestration chips consist of main chips, fluid control modules, signal acquisition modules and external control modules. The main chip is a micro -channel network, which is composed of micro -flow channels, microbes, micr -pumps, etc.; fluid control modules are responsible for the input, output and control of fluid; the signal collection module is used to collect the signal of the sensor; the external control module is used to control the chip Operation.
Features:
Small size: The size of the microfluidic chip is usually a millimeter or smaller, with a small size, which is convenient for integration and carrying.
Fast and efficient: Micro -current control chips can achieve fast mixing, transmission, and separation of micro -streaming, with fast response speed and high efficiency.
Flexible and controllable: Micro -current -controlled chips can be accurately controlled and adjusted by controlling micro valves, micro pumps, etc.
Low cost: Compared with traditional laboratory equipment, micro -current control chips have the advantage of low cost, saving the cost and resources of the laboratory.
principle:
The micro -current -control chip is based on the principle of microfluidicity, and through the control of the fluid in the micro -scale channel, it realizes the mixing, separation, transmission, and control of micro fluids. The operation of microfluidic chips usually regulates the pressure, flow rate and flow of the fluid by controlling micro valves, micr -pumps, etc., thereby achieving control of microfluidic bodies.
Microcide -control chips can be classified according to different application areas and functions. Common classifications include:
Biological chips: used in biomedical research, biological analysis, and biological testing, such as cell culture chips, DNA analysis chips, etc.
Chemical chips: for chemical analysis, chemical synthesis, and drug screening, such as micro -reactor chips, analysis chips, etc.
Environmental chips: used in environmental monitoring and pollutant detection, such as water quality monitoring chips, gas sensor chips, etc.
Common faults and preventive measures:
Leakage: Micro -channels and valves in micro -current control chips are prone to leakage. Pay attention to sealing and connected reliability.
Cover: The micro -channel in the microfluidic chip may cause the fluid to be unable to flow normally due to the blockage of the particles or air bubbles. Pay attention to the purification of the sample and the standardization of the operation.
Drift: Due to temperature and pressure, the fluid in the micro -flow -controlled chip may drift, which affects the experimental results. Pay attention to the control of temperature and pressure.
In summary, micro -flow control chips are integrated chips that use micro -scale channels and microfluidic control technology to control fluid control. It has the characteristics of small, fast, efficient, flexible, low cost. It consists of the main chip, fluid control module, signal acquisition module, and external control module. It controls the precise control and adjustment of micro -flow bodies through controlling microflower valves and micro pumps.
Micro -current -controlled chips can be divided into biological chips, chemical chips and environmental chips based on different application areas and functions. When using microfluidic chips, we should pay attention to prevent common faults such as leakage, blockage and drift to ensure the accuracy and reliability of the experimental results.
