TEDx Talks - How Gold Nanoparticles Revolutionize Cancer and Viral Treatment | Hosam Gharib Abdelhady | TEDxSHSU
The speaker shares their journey from studying pharmaceutical sciences to becoming an expert in atomic force microscopy (AFM). They explain how AFM, a tool that allows imaging at the atomic level, is used to study interactions between gold nanoparticles and DNA. Gold nanoparticles, which are extremely small, are used in cancer treatment due to their ability to target cancer cells and generate heat when exposed to laser light, killing the cancer cells. However, the speaker's research found that these nanoparticles can also interact with and damage DNA and RNA without the need for lasers. This discovery opens up new possibilities for treating cancer and viral diseases, including COVID-19, by targeting cells anywhere in the body without harming healthy cells. The speaker emphasizes the potential of this research to provide safer and more effective treatments, and calls for support and awareness to advance this field.
Key Points:
- Gold nanoparticles can treat cancer by targeting cells and generating heat with laser exposure, but also damage DNA without lasers.
