Abstract: The technology relates to a method of producing a moulded polyurethane hydrogel, for example a condom. The method involves forming a solution of at least one polyurethane having a molecular weight of between about 40000 to about 500000 in a water:organic polar solvent comprising less than about 40% (v/v) water; applying a layer of the solution to a mould; drying the layer of the first solution to form a polyurethane film on the mould; and contacting the polyurethane film with a swelling agent under conditions such that the film forms a polyurethane hydrogel with a swelling agent content of between about 1% to about 95%.

Abstract: A microfluidic system for processing a sample includes a microfluidic CD in the form a rotatable disc, the disc containing a plurality of separate lysis chambers therein. A magnetic lysis blade and lysis beads are disposed in each of the lysis chambers and a plurality of stationary magnets are disposed adjacent to and separate from the microfluidic CD. The stationary magnets are configured to magnetically interact with each of the magnetic lysis blades upon rotation of the microfluidic CD. Each lysis chamber may have its own separate sample inlet port or, alternatively, the lysis chambers may be connected to one another with a single inlet port coupled to one of the lysis chambers. Downstream processing may include nucleic acid amplification using thermoelectric heating as well as detection using a nucleic acid microarray.
