what is THE SURFACE PLASMON RESONANCE , how does it affect by the shape of the imaged particle(sphere, rod , star shaped particles) ?

Thank you for the opportunity to help you with your question!

SPR is a phenomenon that allows real-time, label-free detection of biomolecular interactions. SPR occurs when polarized light strikes an electrically conducting surface at the interface between two media.

Please let me know if you need any clarification. I'm always happy to answer your questions.

Hi,

Thanks for your time, How about the second part of my question " how does it affect by the shape of the imaged particle(sphere, rod , star shaped particles) ? " thanks

Take a case of sillver-silica nanocomposite being prepared under high pressure using sputtering technique, those  deposited at lower substrate temperature showed a narrow distribution of nanoparticles with nearly spherical shape. Increase in substrate temperature resulted in films with a non-uniform size and shape due to the agglomeration of the nanoparticles. This size and shape distribution has a profound effect on the optical absorbance spectra and results in a broad and asymmetric surface plasmon band.

What about the flouorescence ,how will it affects by the broad or narrow surfaceplasmon resonance?
