Abstract:
A centripetally-motivated microsystems platform comprising:a rotatable platform comprising a substrate having an axis of rotation and a surface comprising one or a multiplicity of microfluidics structures embedded in the surface of the platform, wherein each microfluidics structure comprises i) one or a plurality of fluid reservoirs, ii) one or a plurality of detection chambers, iii) one or a plurality of mixing microchannels and iv) one or a plurality of air ballast chambers wherein each of said fluid reservoir is fluidly connected to a mixing microchannel that is fluidly connected to a detection chamber and wherein the air ballast chamber is fluidly connected to the detection chamber by a microchannel, and wherein fluid within the microchannels of the platform is moved through said microchannels by centripetal force arising from rotational motion of the platform for a time and a rotational velocity sufficient to move the fluid through the microchannels.
