Immunodiagnostic Chip Rubber Seals

Immunodiagnostic chip is a biochip technology that uses immunological principles for disease diagnosis and immune status determination. Rubber seals play a crucial role in this technology, as they ensure the tightness of the chip and the stability of the reaction.

The main function of rubber seals is to provide a seal for immunodiagnostic chips, prevent liquid leakage, and ensure a stable reaction environment within the microfluidic channel. These seals are typically made of silicone rubber , PDMS material due to their biocompatibility, chemical stability, and excellent sealing properties. During the manufacturing process, PDMS seals can be replicated in the form of heat-curing prepolymers and then bonded to other parts of the chip such as glass or silicon.

The rubber seals of immunodiagnostic chips need to have good high temperature and chemical resistance to adapt to different experimental conditions and chemical reagents. The low thermal conductivity of PDMS means that seals need to be designed with their thickness in mind to avoid adverse effects of high temperatures on flow characteristics and immune responses.

In terms of application, immunodiagnostic chips and their rubber seals are widely used in hospitals, blood banks, physical examination centers and other places for the detection of hepatitis, venereal diseases, tumors, AIDS and other diseases. By integrating microchannels and the necessary immunoassay program components, these chips can significantly reduce reagent consumption, shorten analysis time, and enable automation.

In terms of market conditions, the market size of the immunodiagnostic industry continues to grow, and the scale of China's immunodiagnostic market will reach 52.5 billion yuan in 2022, showing the huge potential and market demand of this technology. With the continuous advancement and innovation of technology, the immunodiagnostics market is expected to continue to expand.

In summary, immunodiagnostic chip rubber seals are a key component to ensure chip performance and accuracy of experimental results. Not only do they need to have excellent physical and chemical properties, but they also need to be able to adapt to growing market demands and technological developments. With the continuous advancement of immunodiagnostic technology, the design and material selection of rubber seals will also face new challenges and opportunities.
