Two-Photon Fluorescence Imaging and Therapy of Cancer Cells with Anisotropic Gold-Nanoparticle-Supported Porous Silicon Nanostructures

摘要

In this work, we prepared porous silicon (pSi) nanostructures decorated with gold nanoparticles, as probes for cell tissue imaging under two-photon excitation. We also demonstrated that the Au/pSi nanosystems induced cytotoxicity and phototoxicity under two-photon excitation.
