Manufacturing Low-Cost Microfluidic Devises Using Thermoplastic Materials

Researcher Ryan Paswell of Australia's University of New South Wales says that most microfluidic devices can be expensive, difficult to manufacture, and unreliable. Pawell manufactures devices using thermoplastic materials or plastic, with the goal of getting the cost down to $1 while maintaining quality for medical diagnostics. He invented a patent-pending manufacturing method and developed software that automatically detects defects.

    00:00:01 these days complex lab processes can be integrated into a small chip like this microfic is a relatively new field where tiny amounts of fluid are processed for things like healthcare for example in this chip we want isolate white blood cells for Diagnostic purposes so what happens is there's an array with shifted posts and the larger cells the white blood cells

    00:00:24 are bump to one outlet and the smaller cells the red blood cells are allowed to flow freely through the array so you get the white blood cell in one outlet and the red blood cells in the other microtic chips are kind of like the same chips found in your computer but instead of wires they use channels to process fluid instead of electricity a big problem in micro foex

    00:00:46 is devices are expensive difficult to manufacture and unreliable so you can't really market microtic devices if they cost $1,000 each and a large portion of them fail I manufactur microtic devices in Plastics with the goal of getting the cost down to $1 while maintaining the high quality so I've invented a patent pending manufacturing method and developed software that automatically

    00:01:05 detects defects the technology I've invented uh brings down the cost of these microfic devices by using lowcost materials and simple processes so I'm really optimistic about this technology I think it's going to have a huge impact on Healthcare and I'm actively looking for applications in HIV and
