Quantum dots Need help in analysis

Click For Summary

Discussion Overview

The discussion revolves around the analysis of gold quantum dots created for a university dissertation, focusing on their potential applications, properties, and the challenges faced in their production. The scope includes theoretical considerations of quantum dot behavior, practical applications in biology and technology, and experimental challenges in synthesis.

Discussion Character

  • Exploratory
  • Technical explanation
  • Experimental/applied

Main Points Raised

  • One participant describes the creation of gold quantum dots designed for human use, emphasizing their advantages over organic dyes, such as resistance to photobleaching and non-toxicity.
  • The participant questions the benefits of creating gold quantum dots with more electrons, speculating that this might lead to more discrete energy levels and the possibility of photoluminescence (PL) at different wavelengths.
  • Another participant suggests the potential for creating small lasers from quantum dots.
  • There is a mention of challenges faced in the synthesis process, particularly with the solubility of 11-MUA in ultra-pure water.

Areas of Agreement / Disagreement

The discussion does not appear to reach a consensus, as participants express varying levels of knowledge and uncertainty regarding the properties and applications of gold quantum dots, as well as the challenges in their synthesis.

Contextual Notes

Quantum dots! Need help in analysis! :D

hey guys,

so long story short is that I've created gold quantum dots for my uni dissertation. These particles are formed with a protein mesh and been made to not to react with any elements as it's meant to be for human use. These gold quantum dots are being created to be used instead of organic dyes, since they are not prone to photobleaching! Therefore far superior to their counterparts. Further to this they are not toxic. The point of this is to highlight specific parts of the cell for further analysis. Obviously, there are many other uses for them such as quantum dot display, cancer treatment etc. At the moment, I have created single wavelength gold quantum dots with a single electron however if I were to create new gold quantum dots with more electrons, how would this be more advantageous over their single electron counterparts? Would having more electrons therefore mean more discrete energy levels? And therefore can PL at more values of lambda?

Thanks in advance :)

O if you have any question or interested in quantum dots, I will gladly run you through what I've done! Since it's a relatively new tech. I'm actually in the process of perfecting how to make multi wavelength gold quantum dots atm, my previous two attempts have failed due to the 11-MUA not dissolving in ultra pure water (I think).
 
Maybe you could make small lasers.

If this is your research area, shouldn't you already know all of the answers?
 
lol I wish I knew all the answers... Would make life so much easier! I guess that's the beauty of physics - unlimited knowledge to be acquired
