| abstract |
The invention relates to nanovectors of formula (I) that can be used simultaneously for the targeting, imaging and treatment, by means of photodynamic therapy, of cancer cells, and to biodegradable silicon nanoparticles containing a variety of photosensitizing molecules, in particular porphyrins, capable of targeting diseased cells and inducing cell death by means of excitation in the near-infrared region (> 600 nm) in monophotonic and biphotonic modes. According to the invention, in formula (I), (AA) is a porous silicon nanoparticle. |
