“…Concerning the IR exposure of biological systems, as in cancer radiotherapy and photodynamic therapy to fight tumor cells, Au NPs are able to enhance radiation effects via physical, chemical, or biological interactions [ 13 ]. The pure Au NPs show a typical absorption band in the visible region, influenced by the SPR associated with the NPs [ 14 ]. In contrast, the absorption of platinum NPs (Pt NPs) presents resonances in the ultraviolet region [ 15 ], taking advantage of their ability for high-energy photon manipulation to be considered for batteries and fuel cells developments [ 16 ].…”

A strong influence of mechanical action in nonlinear optical transmittance experiments with bimetallic nanoparticles integrated by gold and platinum was observed. The nanostructured samples were synthesized by a sol-gel method and contained in an ethanol suspension. UV-VIS spectroscopy evaluations, Transmission electron microscopy studies and input-output laser experiments were characterized. A two-photon absorption effect was induced by nanosecond pulses at 532 nm wavelength with an important contribution from the plasmonic response of the nanomaterials. All-optical identification of acoustical waves was remarkably improved by optical nonlinearities. High sensitivity for instrumentation of mechano-optical signals sensing particular fluids was demonstrated by using a variable carbon dioxide incorporation to the system.
