N2 - The influence of an optical fringe patterns on the viscoelastic properties exhibited by Au nanofluids samples was evaluated. A sensitive interferometric technique for analyzing optofluidic effects in different samples was implemented. The assistance of the plasmonic characteristics in Au nanostructures allows measuring particular mechano-optical effects at 532 nm wavelength by a Fabry-Perot interferometer to explore multiaxial strains. A representative volume of the sample was studied to determine the stability and maximum viscoelastic properties exhibited by the nanostructures. A vectorial two-wave configuration allows controlling the maximum strain induced in the sample. The oscillating nature of the colloid was examined by using interferometric optical signals reflected from a remnant drop pending at the end of an optical fiber. Nanosecond pulses were used to induce inelastic optofluidic effects. The mechanical parameters were approximated by a nonlinear second order system activated by a Dirac delta functions.
