3D printable materials based on polymeric ionic liquids (PILs)
capable of controlling the synthesis and stabilisation of silver
nanoparticles (AgNPs) and their synergistic antimicrobial activity
are reported. The interaction of the ionic liquid moieties with the
silver precursor enabled the controlled in situ formation and stabilisation of AgNPs via extended UV photoreduction after the printing
process, thus demonstrating an effective decoupling of the device
manufacturing from the on-demand generation of nanomaterials,
which avoids the potential aging of the nanomaterials through oxidation. The printed devices showed a multi-functional and tuneable microbicidal activity against Gram positive (B. subtilis) and
Gram negative (E. coli) bacteria and against the mould Aspergillus
niger. While the polymeric material alone was found to be bacteriostatic, the AgNPs conferred bactericidal properties to the
material. Combining PIL-based materials with functionalities, such
as in situ and photoactivated on-demand fabricated antimicrobial
AgNPs, provides a synergistic functionality that could be harnessed
for a variety of applications, especially when coupled to the
freedom of design inherent to additive manufacturing techniques. [-]
