Several researchers around the world are trying to develop nanoparticle encased sensitizers, because they target cancer far more specifically. We have already achieved that goal with our present sensitizer. While it is not difficult to create nanoparticles, it is quite difficult to control their size and how they aggregate and assemble. It is also important to control how well the nanoparticles penetrate cancer cells. We use a nanoparticle that enhances the sensitizer uptake. Other researchers are working with gold nanoparticles, because it is the easiest nanoparticle to make, but ask yourself this, does cancer have a desire for gold bling ? Probably not, your girl friend may like gold, but cancer prefers sugar. Our nanoparticles look like Sugar to the cancer.
