    Paper-based microfluidic devices can provide practical
    analytics platforms for applications such as point-of-care
    medical diagnostics. So far immobilisation or separation of
    analytes on such devices has received limited attention. This
    study introduces inkjet printed polyelectrolyte patterns as
    possible platforms for immobilisation of cationic and anionic
    compounds through surface charge interaction. Both cationic
    (polydiallyldimethylammonium chloride) and anionic (sodium
    polyacrylate) polyelectrolytes were inkjet printed on a custom
    designed porous pigment coating, having fine particle internal
    pore structure to ensure high surface contact between the
    analytical sample and modified pore walls. Printed
    polyelectrolyte patterns were themselves largely invisible,
    including under UV light. In a proof of principle test, a
    controllable degree of separation of anionic Uranine and
    Tartrazine dyes from aqueous solution passing through a printed
    cationic polyelectrolyte region could be observed. However,
    weakly cationic Rhodamine B could not be captured on anionic
    regions.
