Tip-Enhanced Infrared Difference-Nanospectroscopy of the Proton Pump Activity of Bacteriorhodopsin in Single Purple Membrane Patches
Valeria Giliberti, Raffaella Polito, Eglof Ritter +11
Photosensitive proteins embedded in the cell membrane (about 5 nm thickness) act as photoactivated proton pumps, ion gates, enzymes, or more generally, as initiators of stimuli for…
Plasmonic superchiral lattice resonances in the mid-infrared
Francesco Mattioli, Giuseppe Mazzeo, Giovanna Longhi +14
Recent efforts in the field of surface-enhanced spectroscopies have focused on the paradigm of superchirality, entailing the engineering of the local electromagnetic fields to boos…
Pump-probe Spectroscopy Study of Ultrafast Temperature Dynamics in Nanoporous Gold
Michele Ortolani, Andrea Mancini, Arne Budweg +3
We explore the influence of the nanoporous structure on the thermal relaxation of electrons and holes excited by ultrashort laser pulses ( fs) in thin gold films. Plasmon d…
