The thermocompression bonding technique is one of the key techniques in fabricating microfluidic components, and it can achieve excellent performance. However, if the bonding parameters are selected inappropriately, it can lead to severe deformation of microfluidic channel and damage the fabricated microstructure. In some cases, it can even block the microfluidic channel. We can achieve bonding of different materials, such as PS, PMMA and COP. By using optical microscope and liquidity testing equipment for flow channel, we can accurately evaluate the performance of the bonded components
Based on antigen antibody reaction, unbound protein can be swept away by excess sample, while capture antibodies are immobilized on chip surface by creating covalent bonds.
Different substrate pretreatment before protein immobilized on chip reaction chamber and testing chamber to achieve the different purpose. Covalent immobilization of protein on substrate could Improve the chip stability and repeatability.
Tabletop workstation designed for high speed despensing applications to our chip is computerized automatic positioning, with excellent repeatability, flexible volume range (pl-nl).
Fluorescence intensities reflect the degree of biochemical reaction. Microarrays for different diagnostic markers can be simultaneously analyzed, high automatically, rapidly and efficiently.
