How to Make Quantum Dots

[@LM-gi2ks]

Really informative. Thank you. Several companies are now making commercial quantum dots. Besides using dot size to modify the emission wavelength, it's also possible to tune the output wavelength using a composition gradient in the core material.

[@savijay100]

Excellent!! lecture about the CdSe Dot. I wish all success in your future endeavors.

[@godzilla1922]

After you created your QD cores, what type of organic solvents did you use to wash them?

[@LordMegatherium]

I actually made CdSe QD synthesis optimization as a project yet with the TOP/TOPO method. Also made multishells. Thing is I didn't have to evacuate the vessel that long. The basic synthesis is really this easy though time-consuming due to the purification steps if you're doing multshells. Too bad I didn't have time to do biofunctionalization.

[@TheEric826]

she did great explaining that to the normal person

[@hi92354]

Very nice presentation.

[@novis1atgmail]

@espydude Typically Quantum dots are very useful for research purposes. Its hard to get enough dots to the cancer cells in a living person to be visible, and they can potentially have harmful effects. There is some research to try to do this, but for the most part dots are a research tool currently.

[@AnkitaSingh-bh4zj]

Can you suggest a procedure for MoSe2 nanoparticles and if the synthesis is possible without a glovebox?? Thank you

[@lvb3575]

Can you guys perhaps make a video on how to make Carbon quantum dots?

[@OfficeThug]

Man, I could probably make this stuff in my own lab. We have 2 gloveboxes, 8 schlenk lines and about 10 different distillation columns. Unfortunately our group only works with organic flow-cell battery materials and super organic reducing agents. Our stuff is either lovely black, lovely goop, or extra-lovely tar like substance that spontaneously combusts in air.

I'm in love.

[@نورالمرسومي-ه2س]

Nice but please any precursor use

[@FoodNerds]

This was very interesting 🧐 thank you!

[@brentonpiercy]

Rad. Thanks for posting.

[@Muradsahar]

I need to write an introductory technical paper on quantum dots for uni assingment(history to present, 20 pages), can you recommend some good source with comprehensive explanation on the subject. Articles, rsearch papers, lectures or books?

[@Muradsahar]

I mean specific sources, I do not want to go into deeper resarch, as I am under time constraint.

[@minototta6702]

You are more beatifull than the science you explain.....!!!!

[@niujunking]

thank you soooo much!

[@ishaqktktech4372]

I am BS student we write a review on PdS2 quantum dots. unfortunately we don't work in lab due to lake of time

[@luissapple1]

Is this actually the process to identity cancer cells? Or just a study lab? I'm wondering because it seems most of this could be optimized to provide a streamlined analysis of cancer cells.

[@Pooua]

I don't know how prevalent this method is today, but doctors have been able to identify cancer cells a long time before QD was invented.

Thanks a lot for sharing

[@sonicase]

hmm what's the advantage of quantum dot over a flourescent protein attached to an antibody

[@jameszhang9326]

Not that simple to answer. Depends on the bonding affinity+type and the specific region that you're trying to dye-mark.

[@tongbunsing]

Stearic acid?

[@HiAdrian]

Interesting, thanks.

[@rickmurie5861]

Amazing!

Very interesting.

Did she come up with this process?

[@6Diego1Diego9]

@@jameszhang9326 do you think I'm an idiot James? what's your problem

[@vadymvolodko7252]

I'll use Inplix instructions to make it by myself.

[@oskar12]

@61324852 @61324852 More than likely you'd use the SILAR method for covering the QD with an epitaxial inorganic layer that has a wider bandgap (for coating CdSe you'd use something like CdS, ZnS) see Peng et al, 2003 Large-scale synthesis of nearly monodisperse CdSe/CdS core/shell nanocrystals using air-stable reagents via successive ion layer adsorption and reaction As for who invented QDs, the modern incarnation of what she's working with is attributed to Bawandi and Murray ~ 1993

[@JonathanFosdickNano]

I use carbon to make my quantum dots ;p

[@justaddh30]

@dubtafoo so your greatest achievement is calling people out on the internet with your proper grammar and punctuation? clearly you cared enough to comment. thanks for caring internet tough guy!

[@MultiTuLaLiT]

How size your quantum dot?

[@DrBlueGOAT]

Few nanometers

[@navaneeth_anand]

What is her name?

[@asbaDoce]

I stayed at the "mechanical stimulation" [2:13] part and just couldn't keep the pace from there but it sounds like a lot of fun...

[@niclasbech]

@sonicase proteins are biologically active, nanodots are not. thats my understanding anyway

[@NoahFect]

This sounds like an episode from the "Things I Won't Work With" blog (which needs its own KZbin channel badly.)

[@JustinKoenigSilica]

No, all of these things aren't that bad. There are far worse chemicals out there. This is actually quite manageable.

[@HartleySan]

Cool.

[@justaddh30]

So So So So I start every sentence with the word 'So'

[@hollya.g.86]

So what?

[@voroignis]

She can mechanically stimulate me any time! HEY-OHHH!!

[@nicksanders9148]

THE MARK OF THE BEAST IS COMING! JESUS LOVES YOU ALL AND SO DO I! PLEASE PRAY ABOUT IT!

[@SuperBastardHead]

Why do so many americans overuse the word "So"? Cool gloves though, and I can see you're used to mechanical stimulation.

[@TheBrokenSaint]

@unchellmatt this! Oh god we are all in danger.

[@AbeMoffat]

More of a promise than a look?

[@sonec90]

2:19 You shake that up. Give it that mechanical stimulation.

Mechanical stimulation....

If she ever realizes just how adorable she is, the ease with which she could over throw civilization would be staggering. Geek chicks + handy with dangerous chemicals = SWEET JEEBUS, yes please!

She's had a lot of practice with that mechanical stimulation..
