How Does Nanotechnology Work?

Click For Summary

Discussion Overview

The discussion centers around the physics of nanotechnology, specifically how it works and the methods used to build nanomaterials. Participants express a need for foundational knowledge and examples of applications within the field.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant requests a deeper understanding of nanotechnology beyond its definition, indicating a lack of knowledge about its operational principles.
  • Another participant suggests various topics related to nanotechnology, including sunscreen with titanium nanoparticles, photonic crystals, surface plasmon resonance, and carbon nanotubes.
  • A participant notes that many nanomachines are constructed similarly to computer chips, using etching techniques on silicon wafers, highlighting the complexity and breadth of the subject.
  • One participant describes the use of carbon nanotubes in next-generation computers, emphasizing their ability to allow electrons to travel in a "single-file" manner, which could enhance computational efficiency.
  • Another participant shares an example of using mineral-bearing bacteria and viruses for atom deposition, relating it to both fictional and real-world applications in manufacturing and targeted drug delivery.

Areas of Agreement / Disagreement

The discussion does not reach a consensus, as participants express varying levels of knowledge and interest in different aspects of nanotechnology, leading to multiple competing views and topics without resolution.

Contextual Notes

The initial request for information is vague, which may limit the specificity of responses. The discussion touches on a wide range of applications and concepts within nanotechnology, indicating a broad scope that may not be fully addressed in a single presentation.

Who May Find This Useful

This discussion may be useful for students or individuals interested in the fundamentals of nanotechnology, its applications, and the various methods of material construction at the nanoscale.

Hi, I am doing a presentation on nanotechnology and i don't know what the physics of nanotechnology! can someone find me the basics of nanotechnology physics and how it works and everything pleasezZz. And i don't want a site saying "nano is 1 billiont of a meter" because i already know what nanotechonology is. I just don't know how it works or they build the materials. SO can u please help me? tanx

please someone help me i need serious help
 
Here are a few Nanotechnology topics you could research...

Sunscreen (some sunscreen contains titanium nanoparticles)
Photonic Crystals (Opals in particular will be interesting)
Surface Plasmon Resonance (A bit advanced)
Carbon Nanotubes

Technically nanotechnology is anything that has a scale less than 1 micron, not necessarily as small as 1 nm.

I don't really expect that you can get a lot of help based upon the vagueness of your question. A lot of nanomachines are constructed the same way that regular computer chips are, by etching them onto silicon wafers. The subject covers such a huge range, though, that you can barely scratch the surface in a single presentation.
 
One of my personal favorites is found in the design for next-generation computers, where carbon nanotubes form a conducting filliment so thin that electrons are forced to travel down it "single-file". This means the smallest possible amount of charge (one electron) is distinguishable from no charge, so the presence or absence of individual electrons can be used as bits in computation.

Neat! I hadn't heard of that one before. :cool:
One of my favourites was actually used as the fictional manufacturing method for Iron Man's armour over 25 years ago, and is now being experimented with for real. It's the use of mineral-bearing bacteria, viruses, and such to deposit individual atoms in selected locations. I think that the same approach is being investigated to deliver micro-doses of high intensity drugs and radioactive substances to specific tumour sites.
