Product Description
Microfluidic paper chips using paper as a substrate instead of silicon, glass, polymers and other materials, through a variety of processing technology, processed on paper with a certain structure of the pro / hydrophobic microchannel network and related analytical devices to build "microfluidic control chip", also known as paper chips.
Paper analysis chip is an emerging paper analysis technology platform, which is widely used in medical diagnosis, food safety monitoring and environmental monitoring because of its advantages of simple manufacture, low cost and good biocompatibility. The paper material has the unique and attractive qualities of separation and support in the test device: its composition is inert cellulose, rich in origin, cheap, renewable, easy to handle, recyclable, Easy to use and transport, easy to chemical modification, has good stability and good biocompatibility. Combined with modern printing technology, microfluidic devices can be easily prepared for separation, analysis and detection, making them an excellent material for testing.
Paper chip material selection requirements:
Paper chips, the choice of paper material is critical, to consider a number of factors, such as: sufficient mechanical bearing capacity; immersion in the water phase without significant deformation and disassembly; suitable hydrophilic and hydrophilic easy adsorption and fixation to form a clear test area, and To avoid excessive spillage; Do not degrade biological analytes or other detection reagents; The surface should be uniform in order to reproduce, modify, and generate signals; Reduce the coffee-ring stain effects that are common in conventional methods; Consider the package with the composite material matching effect and so on.
