Device and method for liquid analysis to detect biomarkers

A device for enabling a user to detect biomarkers, the device comprising:

• an element that defines a multiplicity of microfluidic channels that communicate between an inlet duct and an outlet duct;
• the inlet duct communicating with an inlet port at a surface of the element into which a user can introduce a drop of body fluid;
• the outlet duct communicating with an outlet port at a surface of the element, the device also incorporating a resilient elastomeric bladder connected to the outlet port to provide suction;
• wherein each microfluidic channel defines a reaction chamber containing a biomarker-sensitive reagent which provides a colour or a change of colour in the presence of a biomarker, there being a multiplicity of different biomarker-sensitive reagents, one such biomarker-sensitive reagent being provided in each of the multiplicity of different microfluidic channels, each microfluidic channel enclosing a porous hydrophobic element downstream of the reaction chamber, and at least part of the element being transparent so that the colour or change of colour within the reaction chamber can be viewed from outside the element;
• and
• a cover, the cover defining multiple lenses that are above the reaction chambers, and the cover also comprising an openable flap that covers the resilient elastomeric bladder.
