Nanostructures for plasmonic solar cells and biosensing

The key element for real-life plasmonics application depends on the fabrication of subwavelength nanostructures supporting localized surface plasmon resonance (LSPR) with mass reproducibility yet low cost. We have investigated two fabrication techniques for photovoltaic and biosensing purposes, i.e. self-assembly nanoisland and nanosphere lithography, which enable formation of relatively large area LSPR supporting arrays on transparent substrates yet without demanding for expensive manufacturing equipments.
