Gold nanoparticles in radiation therapy: an old story yet mesmerizing
Radiotherapy (RT) is generally considered to be one of the most effective cancer treatments. The primary goal of RT is to accurately induce radiation damage to the tumor while limiting radiation toxicity to a level acceptable to normal tissue. This is accomplished by targeting the tumor with radiation. On the other hand, the status of RT procedures as they stand today is not substantial enough ...
متن کاملGold nanoparticles and their alternatives for radiation therapy enhancement
Radiation therapy is one of the most commonly used treatments for cancer. The dose of delivered ionizing radiation can be amplified by the presence of high-Z materials via an enhancement of the photoelectric effect; the most widely studied material is gold (atomic number 79). However, a large amount is needed to obtain a significant dose enhancement, presenting a challenge for delivery. In orde...
متن کاملEnhanced Radiation Therapy of Gold Nanoparticles in Liver Cancer
Gold nanoparticles (GNPs) were widely used in X-ray imaging and radiation therapy due to strong photoelectric effects and secondary electrons under high energy irradiation. As liver cancer is one of the most common forms of cancer, the use of GNPs could enhance liver cancer radiotherapy. We synthesized polyethylene glycol (PEG)-coated GNPs of two different sizes by chemical reduction reaction. ...
متن کاملGold Nanoparticles for Radiation Enhancement in Vivo.
Enhancing the effect of radiation on tumors would be a significant improvement in radiation therapy. With radiation enhancement, less radiation could be used to achieve the same goals, lessening damage to healthy tissue and lessening side effects. Gold nanoparticles are a promising method for achieving this enhancement, particularly when the gold nanoparticles are targeted to cancer. This liter...
متن کاملEvaluation of gold nanoparticles radio sensitization effect in radiation therapy of cancer: review article
In recent years, the use of gold nanoparticles (GNPs) in radiation therapy has been studied by experimentation and Monte Carlo simulation repeatedly. Although the idea of increasing doses has been raised by high-atomic elements since decades ago, but due to the adaptation of gold nanoparticles with the biological system, scientists have incited more about the various uses of these materials in ...
