Cover Feature: Two‐Photon Fluorescence Imaging and Therapy of Cancer Cells with Anisotropic Gold‐Nanoparticle‐Supported Porous Silicon Nanostructures (ChemNanoMat 4/2018)

Porous silicon nanovectors carrying gold nanoparticles and functionalized with mannose species as tumor targeting agents demonstrate remarkable capability as 2-photon imaging contrast agents. An important photodynamic efficiency of the nanovectors is also observed in human breast cancer cells, with the formation of reactive oxygen species when exposed to two-photon light excitation. Such targeted porous silicon/gold nanovectors provide an interesting opportunity for 2-photon imaging and for photodynamic therapy, and an interesting potential for theranostic applications.
