Discussion Overview

The discussion revolves around the construction of nanoshells in modern laboratories, focusing on their composition, properties, and resources for further information. Participants express a need for clarity on the methods used to create nanoshells, particularly in the context of their applications in medical science.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant seeks information on how nanoshells are constructed, indicating a lack of available resources.
  • Another participant describes nanoshells as nanoparticles with a dielectric core and a metallic shell, noting that their optical properties can be tuned by varying the core diameter and shell thickness.
  • A participant expresses frustration over the difficulty in finding detailed information despite extensive searching.
  • Another participant encourages the original poster and suggests continuing research on the topic.
  • One participant recommends using scientific search engines and library resources to find more comprehensive information on nanoshells.

Areas of Agreement / Disagreement

Participants generally agree on the challenges of finding detailed information about nanoshell construction, but multiple competing views on effective research strategies and resources remain. The discussion does not reach a consensus on specific construction methods.

Contextual Notes

Some participants mention the limitations of general search engines and suggest alternative resources, indicating that the availability of information may depend on specific databases or library access.

Who May Find This Useful

This discussion may be useful for students and researchers interested in nanoshells, their construction methods, and their applications in medical science.

I can't seem to find much information on the construction of nanoshells. If anyone can post a link or briefly explain how nanoshells are generally created in a lab today, I would be very thankful.

I'm supposed to write a paper on nanoshells and their impact on medical science. So any further help will be appreciated.

Nanoshell

Hello,

I have found the following at this website:

Nanoshells are nanoparticles with a unique property — they can be optically tuned to either absorb or scatter particular wavelengths of light. Nanoshells are created from a dielectric core (like silica) and an outer shell of gold or another metal. By varying the diameter of the core and the thickness of the metal shell, Nanoshells can be crafted to reflect or absorb different wavelengths.

Hope this helps, remember that googling with the word "nanoshell" gives useful info.
 
I googled for 3 hours before posting this thread :)

Thanks for the link and advice anyway, though the link didn't provide much information regarding the construction of nanoshells.
 
Hey! extremely interesting subject! Congratulations

I can´t help you, but I encourage you to continue working on it. Good Luck
 
You are right about not finding many useful links on google, Xenorelic. Maybe switching to more scientific search engines like Scirus or using the powerful connection options of your local library's scientific subcriptions, more tempting results are likely to be achieved. I strongly suggest that you search Chemical Abstracts for at least 2004-1998 period, available on CD-ROMs in many instutions. It contains information maybe never obtained elsewhere but a little abstract.
Regards
 
Scirus is great. Thanks.
