Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

open access: yesAdvanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Far-field potentials

Muscle and Nerve, 1993
AbstractFar‐field potentials are produced by neural generators located at a distance from the recording electrodes. These potentials were initially characterized incorrectly as being of positive polarity, widespread distribution, and constant latency; however, recent advances have clearly demonstrated that far‐field potentials may be either positive or

Seismic response of concrete gravity dams under near field and far field ground motions

Engineering Structures, 2019
Near field ground motions trigger higher damage to the structures due to the presence of distinct velocity pulses which are absent in far field ground motions.

From Lingering to Rift: Metasurface Decoupling for Near‐ and Far‐Field Functionalization

Advances in Materials, 2021
Metasurfaces, simultaneously operating in near‐ and far‐fields, can be employed as a promising candidate to implement different functions, thus significantly improving the information density, security, and system integration. Recent works have showcased
