Control of matter on an atomic and molecular scale

Click For Summary

Discussion Overview

The discussion centers on the role of nanotechnology in the control of matter on an atomic and molecular scale, particularly its potential applications in cancer treatment. Participants explore the current state of research, speculative technologies, and the relationship between nanotechnology and traditional cancer therapies.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Ken introduces the topic of nanotechnology and its potential role in cancer research, seeking information on its applications and resources for learning.
  • One participant asserts that nanotechnology currently plays no role in curing cancer, emphasizing that radiation is the primary treatment method.
  • Another participant acknowledges that while nanotechnology is not yet used in cancer treatment, research is ongoing into the use of 'nanobots' for targeting cancer cells.
  • A different participant challenges the feasibility of 'nanobots' in current medical practice, labeling the concept as science fiction.
  • One participant agrees that the idea of 'nanobots' is speculative, referencing the historical context of science fiction becoming reality.
  • Another participant argues that simpler chemical solutions for cancer exist and highlights the unknown complexities of molecular interactions in cells as a barrier to nanotechnology's application.
  • A participant describes a specific technique involving gold nanospheres that could potentially target cancer cells using infrared radiation, citing a source for further reading.

Areas of Agreement / Disagreement

Participants express differing views on the current applicability of nanotechnology in cancer treatment, with some asserting it is not yet viable while others suggest ongoing research may lead to future applications. The discussion remains unresolved regarding the effectiveness and practicality of nanotechnology in this context.

Contextual Notes

Participants acknowledge the speculative nature of some proposed technologies and the limitations of current understanding in molecular biology and chemistry, which may impact the development of nanotechnology applications in medicine.

Nanotechnology, is a study of the control of matter on an atomic and molecular scale right?
I'm currently studying taking this course in my college and I'm wondering if Nanotechnology plays a part in researching cancer cells. Does Nanotechnology helps in treatment of cancer cells?

If possible, are there any free online books that contain information of Nanotech so that I could learn from them?

I'm sorry if there are other threads regarding this. I'm new to this forum.

A big hi guys, I'm Ken from Singapore.
 
Physics news on Phys.org


From what i know Nanotechnology plays no part in curing cancer (at the moment) as radiation is mainly used to cure cancer and this has nothing to do with nanotechnology.

P.S: I think this post would be better in a more advanced section, maybe the biology section but I am not sure.
 


At the moment I don't think it's being used yet, but they are definitely researching the possibility. Think about 'nanobots' that are injected into your bloodstream and find cancer cells to destroy them.

This is science fiction.

As I said, this is not happening yet. Space travel was also science fiction a long time ago.
 


Nicks right. Stuff of science fiction is pursued by physicists more than anything else, so this is in no way a negative to Nicks answer.
 


Chemistry will always have simpler solutions for cancer. the problem is not that nanotehnology is not evolved enough ( it really isn't), it's the fact that most of the molecular mechanism of reaction and interaction in cells are mostly unknown.

Proteins can be considered nanobots, quite functional ones.
 


There is a technique (still in the developemental stages) that would use gold nanospheres injected into the body. These little balls would be of a carefully controlled diameter, and would attach themselves to cancer cells. The body would then be bombarded with IR radiation at a wavelength equall to the size of the nanospheres.

Result; the spheres heat up, but nothing else in the body does. Cells in direct contact with the nanospheres (which should only be cancer cells) get cooked, and other cells receive no damage.

I read it in SciAm awhile back. http://www.dddmag.com/news-nanospheres-cancer-cells-032409.aspx" to articles from several publications.
