As compared with bulk materials which possessing good malleability, elevated mechanical strength and electric/magnetic properties; metals nanoparticles possess characteristics physical and chemical properties because of their small-size, fine surface, and quantum-size effect. Noble metals called plasmonic nanoparticles are distinguishing from other nanoplatforms such as polymeric

and magnetic nanoparticles and semiconductor quantum dots by their characteristic surface plasmon resonance (SPR). This SPR is the collective oscillation of the surface electrons of nanoparticles. When the frequency of light

photons matches with the natural frequency of electrons present on the surface of nanoparticles, which are oscillating against the restoring force of positive nuclei then resonance condition is established. SPR in nanometer-sized structures is termed as localized surface plasmon resonance.

I am working with silver nanoparticles. I got the SPR peak at about 290 to 300 nm. But I didn't know whether my result was correct. Please anyone provide me with the actual value for SPR peak of silver

Biosynthesis of nanoparticles may provide SPR peaks around 300 nm

Thank you so match Irfana Amri
