Abstract:
1. An optical disc for processing and analyzing a sample, comprising: a substantially circular substrate; a cap portion; a channel layer positioned between said substrate and said cap portion, said channel layer comprising at least one fluidic circuit, said fluidic circuit comprising: an analysis chamber connected to said second end of said mixing chamber for analyzing the mixed sample, and wherein said sample circuit further comprises: a sample loading chamber configured to receive and hold said fluid sample, said sample loading chamber comprising a sample inlet port for introducing the sample into the sample loading chamber; a sample pass through channel having a first end and a second end, said first end of said sample pass through channel connected to said sample loading chamber and said second end of said sample pass through channel connected to said first end of said sample flow channel; a second valve positioned within said sample pass through channel and configured to prevent said sample from flowing out of said sample pass through channel until said optical disc is rotated at a predetermined speed which causes said sample to be forced through said second valve; a separation chamber having an inlet port connected to said second end of said sample pass through channel and to said first end of said sample flow channel, said separation chamber configured to separate said portion of the sample when the optical disc is rotated; and wherein said fluid circuit further comprises: a fluid loading chamber configured to receive and hold a fluid, said fluid loading chamber comprising an inlet port for introducing the fluid into the sample loading chamber; a fluid pass through channel having a first end and a second end, said first end of said fluid pass through channel connected to said fluid loading chamber and said second end of said fluid pass through channel connected to said first end of said fluid flow channel; and a third valve positioned within said fluid pass through channel and configured to prevent said fluid from flowing out of said fluid pass through channel until said optical disc is rotated at a predetermined speed which causes said fluid to be forced through said third valve.
