Abstract:
1. A method for the automated analysis of at least one liquid sample involving the use of at least one microfluidic structure, the method comprising: providing at least one microfluidic structure adapted for spinning around a spin axis to generate a centrifugal force wherein said at least one microfluidic structure comprises an inner position and an outer position relative to said spin axis in a direction of said centrifugal force, said at least one microfluidic structure including: transferring said at least one liquid sample into said first fluid reservoir; spinning said at least one microfluidic structure around said spin axis so as to transport said at least one liquid sample into said one or more dead-end recesses by said centrifugal force; transferring a control fluid into said first fluid reservoir or said second fluid reservoir; spinning said at least one microfluidic structure around said spin axis to transport said control fluid into said flow channel by said centrifugal force so that said control fluid is at least present at said one or more respective recess openings of said one or more dead-end recesses, said control fluid generating a barrier to flow and diffusion of said at least one liquid sample contained in said one or more dead-end recesses; and analyzing said at least one liquid sample contained in said one or more dead-end recesses.
