Michael Faraday synthesised gold nanoparticles back in 1856. Over time, scientists have managed to synthesise a variety of nanoparticles and nanomaterials that can be used in a healthcare setting.
This lecture was filmed on 24 November 2022.
Nguyen TK Thanh held the prestigious Royal Society University Research Fellowship (2005-2014) and is a Professor of Nanomaterials. She is based at UCL Nanomaterials Laboratory, at The Royal Institution of Great Britain, the oldest independent scientific research body in the world and Biophysics Group, Department of Physics and Astronomy. She is currently Vice Dean for Innovation and Enterprise, Maths & Phys. Sci. Faculty, University College London.

Yeah, sorry, it wasn't just the open second mic, it was the lack of warmth with the sound as well. Too much treble. When you have a speaker with a heavy accent you need perfect sound. I left after 2 minutes, even after the extra mic was turned off.
There is a sadly out-of-print book by Ed Regis called "Nano" that does this same thing with the history vs current work and speculative engineering.
Of course the best layman's work is still Drexler's 2013 "Radical Abundance" on Atomically-Precise Manufacturing (APM) and Fabrication (APF). <- What actually functionalized molecular engineering is now called instead of his 1980's-coined tern from "Engines of Creation" (1986) "Molecular Nanotechnology" which was rapidly Bowdlerized in the successive years.
I'll watch this IF they fix it..
I think this is the bootleg version. 👀 I can hear the freaking audience👂😂. Could someone please turn on the caption subtitles?
So many presenters eventually get around to "So I wrote a book…" but it's not usually the textbook for their course. I mean, fair enough, it's a book, and I'm sure you sell a reasonable number, but it's hard to excite the audience with that kind of book. Fortunately that wasn't your last book.
Why on Earth do you publish such rubbish? It just allows people to believe that you're a bunch of amateurs and bypass what you present. No matter how interesting the presenters are. I'd like to know their opinion about how they are being represented.
I wanted to enjoy this, but a factual statement just a practical matter is that the lecturer acent made it harder to understand
The combination of bad audio-quality, hearing someone off camera's voice and sounds, the positioning of the microphone of the speaker and the quality of the English pronunciation of the speaker makes it really difficult for me to follow this otherwise very interesting lecture. This is a pity, as many others will surely be unable to understand the information.
This is the first time I have felt the need to hit thumbs down on an RI video. I don't belive anyone could learn much thru Mr. Sniffer's hot mic, except, maybe hire a better sound man. They put sliders and knobs on audio mixers for a reason. I can't imagine how disappointed the person giving this lecture must feel.
On many counts this is a very poor effort by the RI and should be deleted.
I’m going to be real here. I use your lectures to sleep but when it’s some lady I struggle to understand or some guy popping balloons that isn’t working.
Unwatchable or rather unhearable, and this is not only talking about sound quality.
Nano materials are destroying the planet, from plastics to metals to hybrid allows. These "scientists" are irresponsible and should be stopped.
I've been trying to get to this for most of the week, finally sat down Sunday to have a watch, and the initial lecturer's answer about the start of nanotechnology has put me off immediately. As we learned it very early on, technology is "any device or tool that makes work easier". Yes, I get the in-nature aspect, but in practical use, technology is via human application.
What's the animal world for nanometer?
If we're to have communal gatherings on furthering a process, relating accurate information is more than just semantics or 'being PC'.
She is really hard to listen to. "Michael Friday" LOL
Brilliant, thank you. I really enjoyed this lecture.
China is a superpower in NANOTECH. America will need another 20 years to cath up to be honest.
Cut it out, Faraday, we know it’s you ya goof
This looks from the outside a British institute ! Because more and multie more of the same ,all talk….England needs it's constitution respecting under an English Gov not a business failure called UK….this is the only topic of interest until it is completed full stop

The bell… seriously? I was absolutely disgusted by that. She really found her stride there and was covering some good ground – really interesting stuff.
And like some cheap game show this bell rings and she just stopped.
I wondered what was happening – is this part of the lecture???
Then some guy comes out brandishing a book about ‘How to Lecture’???
Disgraceful towards someone who clearly has an expert grasp of, leads and contributes much to this vital field and had me gripped in this lecture.
RI – please. Don’t do that again. It’s disgraceful to cut someone off like that. Seriously – change the format or something.
Suppose Evolution on Earth had occured in such a way that there are 96 amino acids instead of 20 and DNA synthesis occurs in the same way as today. DNA has 12 different bases, then the Minimum of bases per DNA codon would be found When an ant has the Mis-mutation the DNA sequence in the ant is modified fr9m the guanine nucleotide base to that of another purine base called adenine,so that the Ribosome takes up this modified codon CCG instead of UCG and syntetesizes a false pair of walking legs synapsed to the left antenna with a foreleg of the first left side in the thorax. As you can see in the codon box, serine can be decoded to any one of the 4tRNA anti-codons that is found in the pair of either of the 2 premature termination stopcodons UAA,UAGand UGA that can result easily in the pair of false walk8ng legs 9n the left side of the antenna and first left foreleg , For e.g. ,an UCG Codon for Amino acid is Incorrect for attaching to a tRNAserine, instead of a possibility of the tRNA specifically attachIng to the Proline which is coded by a 2 pair of codon Shown in the codon box. The amino acid Serine attaches to anyone of the 4-Anti-codon tRNA as shown in the codon box. There is a 4*4 possibility for 96 amino acids instead the 64 t-RNA codons. This is the reason why Wobbling hypothesis is going to be only specific against Consequence of the closure of Anticodn-codon in a way that would become mis-sense wrongshape bases for the growth of the pair of false walking legs in the Mis-sense mutant Ant.The codon box can be referred to,for point mutations, Nonsense Mutations ,frameshift mutations,but rarely for a Mis-sense specific mutation in the DNA of multicellular living ants.
Me: 💭 👋Only a minute in, and this lecturer seems unique and I'm excited for another world class Royal Inst-
