We theoretically investigate optical properties of plasmonic polymers consisting of chains of TiN and Au nanoparticles. The plasmonic polymers are more flexible, and have hot spot excitation between two adjacent particles and anisotropic resonant modes. We find that the strong near-field coupling changes absorption and scattering spectrum compared to the random dispersion of nanoparticles at the same volume fraction. Thus, a gradient of laser-induced temperature rise is also varied. In biological medium, this temperature increase has a significant influence on the inactivation of proteins. In this work, we employ the Arrhenius model to determine the protein inactivation.
