If you’ll excuse the ridculously overdramatic soundtrack 
Synthesis of CdSe nanocrystals by injection of cadmium and selenium precursors into a high boiling point coordinating solvent at 360 degrees C. ~3nm particles of CdSe are initially generated. The intense color results from the quantum confinement effect on the electron as a result of the nanocrystal size being less than the Bohr radius of the exciton. Thus, as the particles grow larger, they become redder in color. A size series was generated by allowing the crystals to grow at 280C over a period of ~2 minutes. The visible spectrum from 515nm (green) to 650nm (red) was covered.
Video Rating: 4 / 5

the final version is better… oh well, still a masterpiece!

Epic

what is said overdramatic music?
[Reply]
what happens if u mix them all together…?
[Reply]
Looks like every video (whatever it’s about) has to use this music.
[Reply]
hey i love this videos, were i want to prepare some quantum dots like yours, were can i find the procedure
[Reply]
music fail

I guess you are refering to the microscopic holes in nitrile gloves, that are in fact large enough to let nano-particles pass through?
If that is the case, I wouldn’t be so sure, that they “don’t protect”. There still needs to be some sort of cause as to why they should enter these holes and your body.
Unless it is a known problem, in which case I happily stand corrected.

sure it is
[Reply]
Absolutely agree. Cd is exceptionally toxic and the nanometric scale indicates they will easily permeate cellular membranes

Watch out for a company on the London aim market going places with this technology. ticker symbol nano.
[Reply]
is that edible?
[Reply]
i see what you mean by overly dramatic soundtrack haha, although it does build with the experiment. i loved watching the quantum dots at sussex uni, i was amazed by them. nice video.
[Reply]
wow good video
[Reply]
Excellent video and super work! I wish I could have been there when you did it!

They can be used in vivo after ligand exchange, maybe CdSe won’t be used but InP could be.
[Reply]
requiem for a synthesis
[Reply]
the purple nitrile gloves are very fancy and fashionable but they don’t protect against possible spills of QD in the sizes you are synthesizing: not smart. They will never be used in vivo in humans.
[Reply]
not TOPO or TOP, is paraffin

Song-Requiem for a dream!
sound even better with 2pac on it,-mix-.
[Reply]
I think they used a coordinating solvent that consists of TOP and TOPO. This solvent is very important to synthesize nanopartices because it can stablize the result colloidal dispersion as well as electronically passivate the semiconductor surface.
[Reply]
nice!
[Reply]
wow, you guys aren’t scared of getting cataract by turning that UV lamp upside down?
[Reply]
The overdramatic music was good.
[Reply]
TOPO
[Reply]
I think TOPO
