Quantum dots have huge potential contributions to make in biological
imaging and diagnostics. Despite having been studied in imaging for
several years now, reports on quantum dot toxicity have been
inconsistent and very little invivo studies have been published.
I'm doing a research project on the toxicity of quantum dots and the
risks/benefits associated with their use. So far I have gone through
most of the literature available, and I'm still on the fence. I was
hoping to stimulate some discussion in this area, and get some feedback
about how others that know a bit about it feel.
Do you think quantum dots are toxic? Do you think evidence supports
their use in humans for diagnostics in the near future? What do you
think the main risks are?
Furthermore, if you have information/opinions on environmental release
or occupational hazards, I'd love to hear about it. |

I'm always surprised at people who start discussions like this.
The question of whether a particular chemical substance is toxic or
not is not a subject for opinion. It is something that has an answer,
and that answer is most easily determined by objective scientific
study.
Incidently, there isn't just once arrangement of atoms called a
"quantum dot" so there will not be one answer for the entire class of
objects called "quantum dots".
If you want to know the answer to your question for a particular type
of quantum dot, then the thing to do, if there is nothing yet in the
literature, is acquire experimental animals and perform a controlled
study.

Again, this isn't a proper subject for "opinion". Hazards, if any, can
be determined with objective research.
