Three microfluidic test strips

The Science Behind the Strip

  • Microfluidic devices, made of diagnostic strips or discs, transport, protect and detect important samples of blood or other fluids. They give patients and providers the information they need to diagnose and explore treatment. Perhaps most importantly, they enable people to put the power of health information in their own hands – quickly and at the point of care.

  • Manufacturing microfluidic devices requires sophisticated techniques. These sensitive strips or discs transport, protect and detect important samples of blood or other fluids that give patients and their caregivers the crucial information they need. Microfluidic devices are usually small and have intricate channels and circuits which require a lot of attention and care to assemble and manufacture.

    This paper will take you through tape components used in microfluidic device design. It will outline common, required steps to manufacture them.

  • Manufacturing challenges can often complicate the already demanding job of medical device design.

    To help you successfully get ahead of these challenges, we compiled our knowledge from working with design engineers and device manufacturers around the world into a guide – “A design engineer’s guide to manufacturing challenges: Finding balance between design, material & production.”

    It will help you learn from obstacles others have experienced, ultimately helping you navigate the development process more efficiently.

  • Guillermo Urquia has diabetes and needs to monitor his blood sugar levels regularly. He simply pricks his finger, transfers the blood onto a test strip and receives an almost instant result. But how in the world do those tiny little test strips work? Read more in 3M Newsroom article Science Behind the Strip.
