Abstract:
A microfluidic method comprising:taking a microfluidic device comprising a substrate, and a plurality of microvolumes at least partially defined by the substrate, each microvolume comprising a first submicrovolume and a second submicrovolume in fluid communication with the first submicrovolume; adding fluids to the first submicrovolumes; applying a centrifugal force to the device by rotating the device about a first rotational axis to cause a same volume of fluid to be transported to the second microvolumes from the first submicrovolumes; and transporting fluid in the first submicrovolume to an outlet submicrovolume that was not transported to the second submicrovolume when the device was rotated about the first rotational axis by rotating the device about a second, different rotational axis.
