Significance: Demonstrated that rectangular shaped metallic nanostructures (Zero-Mode Waveguide) further improves the detection of single molecule fluorescence over their circularly shaped counterparts and therefore, opens new possibilities to achieve brighter fluorescence emission, faster lifetime and smaller detection volume.

Significance: We show that the aluminum photocorrosion is related to the nonlinear absorption by water in the UV range leading to the production of hydroxyl radicals. Different corrosion protection approaches are tested using scavengers for reactive oxygen species and polymer layers deposited on top of the aluminum structures.
