T
he development of personalized and non-invasive therapies based on new nanoparticles is a major challenge in medicine. In
this context, we studied different nanoparticles for cancer therapy.
Firstly, we analyzed the biological efficiency of hollow organosilica nanoparticles. Porous systems are used to be applied to
drug adsorption and delivery. In this case, we have loaded two anti-cancer drugs, which have been used to perform in vitro
investigations in order to demonstrate their biocompatibility and their potential as drug carrier vehicles to treat cancer.
Moreover, nanoscience has grown considerably in cancer treatment with nanoparticles activated with stimuli as Mn2+-doped
Prussian blue nanoparticles. They are many advantages as their flexible structure, porosity and biocompatibility. Indeed, Prussian
blue has been approved by the Food and Drug Administration for human. We have demonstrated for the first time that these
nanoparticles acted as efficient agents for photothermal therapy under Two-Photon Excitation (TPE) and induce an almost
eradication of malignant cells.
Finally, in order to respond to increasing demand for new therapies, the PhotoDynamic Therapy (PDT) has arisen as an alternative
to chemo- and radiotherapy for the non-invasive selective destruction of small tumors. PDT is based on photosensitizers
activation by irradiation. To enhance the selectivity towards tumor cells and the efficiency of PDT, the photosensitizers are
encapsulated in Periodic Mesoporous Organosilica (PMO) nanoparticles. To go further in the biomedical proof of concept of
therapeutic nanoparticles, we are currently developing an animal model as Danio rerio (zebrafish) to study cancer. We have
implanted fluorescent human cancer cells in zebrafish larvae in order to establish a detectable tumor xenograft. Then, we have
intravenously injected PMO for TPE-PDT in zebrafish and irradiated the tumor site with a pulsed laser. The strong decrease in
tumor size let us imagine developing such model to test the biomedical potential of different nanoparticles.
