Hello!
I am in my last year of high school physics, and for our final project we are given the opportunity to research a topic we are interested in. My chosen subject is the use of gold nanoparticles in cancer treatment. Although I have just begun my research, I am having a tough time finding answers to a few of my questions. Some of them I have no idea how to answer and some of them I have a general idea of what is going on, but I just want to ensure that I have the right information before I put it into my project. The questions that I have at the moment are:
On an atomic level, why do the gold nanoparticles heat up when exposed to infrared EMR?
Why are scientists using the wavelength of EMR that they are using? (approx. 782 nm)
Since this is below the threshold frequency of gold, the photoelectric effect will not occur. Would an ejected electron not damage the cancer further or would it cause more damage to healthy cells?
Does the Compton effect occur in this type of treatment? Does it have different advantages/disadvantages than using the photoelectric effect?
These are all of the questions I can think of right now, and I'm sure I'll have more in the future once I get deeper into my research. Any help would be greatly appreciated, even if you could just point me in the right direction in terms of a paper to read or something along those lines. I'm so excited to learn more about this topic and look forward to reading your answers. Thank you! :)
