The aim of this collaborative research project is to study the collective optical behaviour of self-assembled nanoparticle arrays and their internal photophysical processes, and to explore their feasibility for plasmon nanolasers and biosensors.

Tasks and expected results:

• to study how the pattern and symmetry of nanoparticle‘s (NPs) arrays impact the surface lattice resonance (SLR) and introduce methods to enable active tuning of the SLR wavelength;
• to study the internal photophysical processes of SLRs by comparing NP in arrays versus NPs in solution;
• to use the SLRs of these self-assembled NP arrays applicable to create a surface plasmon nanolaser;
• to use 2D plasmonic structures for biosensing applications in mast cells stimulation related diseases;
• to develop templates for NP assembly employing controlled wrinkling in combination with soft lithography that can be up-scaled to macroscopic areas and is compatible with continuous roll-to-roll processing.
