How to Make Quantum Dots

[HamzaaAbu]

Thanks Charli! I understand you use CdSe quantum dots to bind with and to identify cancerous cells.

I would like to learn the process of assembling quantum dots with mesoscopic TiO2 nanoparticle films for harvesting light and improving photon to charge carrier generation in solar cells.

Could you provide me any pointers like video links or online information. Thanks!

[TheNeochemist]

Thank you Charli Dvoracek for that great quantum dot video among all others to date, it is quite informative instead of flaunting, as some others is!

[jose2012rodriguez]

Its a bong!!! :D

[KillerXtreme88]

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

[sonicase]

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

[niclasbech]

@sonicase

proteins are biologically active, nanodots are not.

thats my understanding anyway

[voroignis]

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

[unchellmatt]

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!

[TheBrokenSaint]

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

You shake that up. Give it that mechanical stimulation.

[iLuVRmC]

she could mechanically stimulate me

[likuidmotion]

I have no idea what she's talking about, but she's hot.

[marshalt]

Yawn.  who cares?

[bkwilsey]

Damn it!!! Now my head hurts.

[bkwilsey]

Damn it!!! Now my head hurts.

@CENonline Is that fire blanket made from asbestos? It looks like it but I could be wrong. Protect yourselves from it if I'm right, and ignore me if it's just a fiberglass fire blanket.

Mechanical stimulation....

[dave1y2000]

Nice presentation. Just ditch the lab coat next time;) Wrrrrawr!!!!

[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...

Simple?! Easy?! Hmmm... My hat's off to you if this process replaces something even more daunting. I look forward to the day I see a video that makes THIS one obsolete-- "... now we take a heaping teaspoon of this, and mix it in with a dash of that... not too much, oh course--"

If your processes and procedures yield inexpensive, high-efficiency solar panels, you have my respect and support.

[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.

[BigMTBrain]

@2:12 - OH, YEAH for mechanical stimulation.

[NoahFect]

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

[MackTuesday]

Cute female scientists are the most awesomest creatures ever.

[hi92354]

Very nice presentation. 

[dlbattle100]

She's obviously a God hating science-loving mad witch doctor, burn her at the stake!

[espydude]

Here's another american tick, getting aroused over anything. So, what do you have to say about that? Even though I don't understand the terminology, what they are doing is really cool. Being able to target cancerous cells for quantum dots to attach to, to give the surgeon the ability to cut out only the bad cells? Color coded cancer cells in effect. Sounds like a win, maybe you she get aroused about that.

[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.

[arnoikke]

I have no idea of what she's saying but she sure had my attention!

[justaddh30]

So

So

So

So I start every sentence with the word 'So'

[dubtafoo]

@justaddh30 So, your greatest achievement in life is to point out little things that nobody cares about? So, you're definitely greater than say someone who's helping to cure cancer?

[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!

[61324852]

that's good.

but I have a questions...

what method do you use for shell?

[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

[SuperBastardHead]

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

[Fivoelk]

@SuperBastardHead We Americans have a lot of verbal ticks like that. Many are regional (the US is a big place), but they spread to others given time. The primary factor in what becomes a part of our language is determined by what is easiest to say in many cases. Words like "so" or "basically" give off a more casual atmosphere or words can be determined by what is considered "cool" at the time no matter how much they regret speaking like a fool in 2 years time.

[dan428]

@SuperBastardHead Everyone has certain mannerisms.. some Brits overuse the word "right"..

[abemoffat]

More of a promise than a look?

[HartleySan]

Cool.

[HiAdrian]

Interesting, thanks.

[6Diego1Diego9]

Did she come up with this process?
