Refereed Conference Meeting Proceeding
In this paper we present a novel dissolvable film (DF) based valving architecture for use on the centrifugal microfluidic platform. We seal fluidic reservoirs on a disc substrate with a series of these valves such that, by pulsing the spin rate, the next valve in the series is opened. Thus centrifugal flow control advances from ‘analogue’ scheme, where valves are successively opened by incremental steps of the rotational frequency, to a ‘digital pulse’ based method. The performance of these valves is demonstrates through a disc designed towards multi-parameter water quality monitoring.
