CYTOP® Fluoropolymer Hydrophobic Coatings For Digital Microfluidics and Biochip Application

Amandeep Jindal, Project Manager- Senior Product Development Researcher, AGC Inc.

Digital microfluidics applications are at the forefront of enhancing precision in handling small liquid volumes, enabling diverse functions including medical diagnostics and chemical synthesis. The integration of a hydrophobic fluoropolymer layer becomes indispensable within these systems to enable precise control over droplet movement, prevent undesirable interactions, namely biofouling, and ensure the seamless flow of fluids. CYTOP®, with its highly favorable attributes including hydrophobicity and stability in devices for biochip applications, are used in mass-produced products; with its three available grades offering tailored functional groups: CYTOP®-A with carboxy terminals, CYTOP®-M with silane terminals, and CYTOP®-S with comprehensive fluoro-functional groups. It showcases CYTOP®’s strengths of recognized quality and characteristics, and its supply stability. This discussion highlights on the importance of digital microfluidics and the significance of CYTOP® in such digital microfluidics devices, showcasing its suitability and importance.
