  • Paperfuge: An integrated paper-based centrifugation and microfluidics platform for low-cost diagnostics
    Patent number: 11331665
    Abstract: A microfluidic centrifuge is provided that includes a microfluidic disc having a pair of through holes that include a first through hole and a second through hole, where the pair of through holes are disposed symmetric and proximal to a central axis of the microfluidics disc, where the microfluidics disc includes a sealable input port and a sealable output port, where the sealable input port and the sealable output port are connected by a microfluidics channel, and a pair of tethers disposed through the pair of through holes that are disposed to twist about each other for unwinding where the tether unwinding is disposed to interact with the through holes, where the microfluidics disc rotates about the central axis.
