Electronic interactions at the nanoscale represent one of the fundamental problems of nanotechnology. The Excitons and plasmons are the two most typical excited states of nanostructures, which have been shown to produce coupled electronic systems. In the center of in-depth and fundamental comprehension of nanoscale interaction is located novel engineered design of suprastructures using nanomaterials. Here, we report exploration of various interactions in nanowires and polymerica materials to induce sensing and imaging properties through mobile excitons of nanowires and localized plasmons of metallic nanoparticles. its experimental validation and the potential practical applications of such nanoscale systems are announced. Modulation of exciton–plasmon interactions can serve as a wavelength-based biodetection tool, which can resolve difficulties in the quantification of luminescence intensity for complex media and optical pathways.
