Cancer Therapy Gold Nanoparticles In Cancer Treatment

Gold nanoparticles are emerging as promising agents for cancer therapy and are being investigated as drug carriers photothermal agents contrast agents and radiosensitisers. Nanoparticles and nanostructured materials are one of the most promising developments for cancer therapy.

Anti Cancer Properties Of Silver Nanoparticles

Gold nanoparticles that act as drug delivery systems in conjugation with chemotherapeutic drugs typically range in size from 10 to 100 nm.

Cancer therapy gold nanoparticles in cancer treatment. Gold nanoparticles magnetic nanoparticles based on iron and its oxides and other metal. Cancer is one of the leading causes of death worldwide. Materials international 2019 1 1 013 024.

Gold nanoparticles cancer therapeutics cancer diagnosis photothermal therapy radiation therapy introduction according to the world health organization who cancer accounted for 79 million deaths in 2007 making it the leading cause of death in the world. Gold nanoparticles absorb high levels of ionising radiation boosting the impact of radiotherapy treatments that work by damaging dna in tumour cells. In the last two decades the development of nanotechnology has facilitated our ability to design new nanoparticles for the diagnosis and treatment of cancer.

A method to make radiation therapy more effect in fighting prostate cancer is using radioactive gold nanoparticles attached to a molecule that is attracted to prostate tumor cells. Lim z li j ng c. Gold nanoparticles gnps can play a significant role in this regard since gnps can be used as radiation dose enhancers and anticancer drug carriers.

Tailored gold nanoparticles for cancer imaging and therapy. Including peg coating the nanoparticles measured to be 130 nm in diameter. The combined use of radiation therapy and chemotherapy is commonly being used in cancer treatment.

The side effects of the treatment can be further minimized through targeted delivery of anticancer drugs and local enhancement of the radiation dose. This review introduces the field of nanotechnology with a focus on recent gold nanoparticle research which has led to early phase clinical trials. Gold nanoparticles in cancer therapy.

In photothermal cancer therapy many gold nanoparticle molecules are used in each test and they must all be uniform in size. Researchers believe that this method will help concentrate the radioactive nanoparticles at the cancer tumors allowing treatment of the tumors with minimal damage. In this chapter we reviewed the applications of gold nanoparticles as contrast agents for cancer imaging including optical imaging photoacoustic imaging and x raybased imaging.

Current therapies employed for the treatment of cancer include surgery chemotherapy and radiation therapy among others.
