A recently granted patent (Publication Number: US11819548B2) discloses a method for treating solid tumor cancer by administering a composition of inorganic nanoparticles via intra-tumoral injection. The method involves determining the volume of the nanoparticles within the tumor using radiography or computed tomography and exposing the tumor to ionizing radiation. The inorganic nanoparticles must provide a specific number of electrons to the tumor, have a minimum theoretical density and effective atomic number, and occupy a specific percentage of the tumor volume.

The patent claims specify that the ionizing radiation used can include X-rays, ion beams, electron beams, gamma-rays, or a radioactive isotope. The composition of inorganic nanoparticles can be made of various materials such as oxides, metals, or mixtures thereof. The nanoparticles' size range, electron density, and the calculation of electrons provided to the tumor are also detailed in the claims. Additionally, the method allows for a combination of inorganic oxides and metals in the nanoparticles, emphasizing the importance of the nanoparticles' characteristics in effectively treating solid tumor cancer.
