TLDR
A variety of configurations and formats have been devised to exploit the phenomenon of surface plasmon on metal dielectric interfaces for sensing a variety of significant analytes, such as pesticides and explosives, pathogens and toxins, and diseased tissue as discussed by the authors.Abstract:
A variety of configurations and formats have been devised to exploit the phenomenon of surface plasmon on metal dielectric interfaces for sensing a variety of significant analytes, such as pesticides and explosives, pathogens and toxins, and diseased tissue. Researchers continue to aim at detecting lower concentrations in smaller volumes of samples in real time. A new research field, called nanoplasmnonics, has emerged in this regard.read more

Detection of bacteria using bacteriophages as recognition elements immobilized on long-period fiber gratings.
TL;DR: This paper presents for the first time a study of long-period gratings applied for label-free detection of specific bacteria using physically adsorbed bacteriophages, and shows that the device allows for real-time monitoring of phenomena taking place on the sensor's surface, including phage-bacteria interactions.

Notizen: Radiative Decay of Non Radiative Surface Plasmons Excited by Light
E. Kretschmann,H. Raether +1 more
TL;DR: In this paper, it has been shown that the non-radiative mode excited by light can also radiate under certain conditions if they are excited by electrons (grazing incidence of electrons on a rough surface or at normal incidence on a grating).
