Plasmonic imaging has exhibited superiority in label-free and fast detection to single nanoparticles due its high sensitivity temporal resolution, which plays an important role environmental monitoring biomedical research. As containing plenty of information associated with particle features, plasmonic been used for identifying the sizes, shapes, permittivity.

Directionally scattered surface plasmon polaritons (SPPs) promote the efficiency of plasmonic devices by limiting energy within a given spatial domain, which is one key issues to devices. Benefitting from magnetic response induced in high-index dielectric nanoparticles, unidirectionally SPPs have been achieved via interference between electric and resonances excited particles. Yet, as low-index nanoparticles too weak, directionally are hard detect. In this work, we demonstrate forward single...

Benefitting from high sensitivity, real-time, and label-free imaging, surface plasmon resonance microscopy (SPRM) has become a powerful tool for dynamic detection of nanoparticles.

With the development of advanced nanofabrication techniques over past decades, different nanostructure-based plasmonic fiber-optic sensors have been developed and presented a low limit detection for various biomolecules.
