I love how its so easy to take notes of this and it doesnt feel boring😂

One dislike was from free science lessons lol

Thank you so much for these videos, you covered what we did in class for weeks in a few hours (yes, i have been binge watching these) they’re so easy to listen to, don’t get boring and are easy sources for notetaking. YOU SAVED MY EXAMS❤

[Canjeero]

Way more easier to pay attention to than the textbook, thank you

[iamthewelcher]

Good vid. Straight to the point.
But now I do wanna know more!

[Elipson]

This help me do my Chemistry poster by a lot thank you

Hello there, I have a request. Can you please enable translating, so that people like me can use this video for educational reasons; like showing a foreign class this video.If you would enable translation so that everyone can contribute to your channel as a whole. Thank you, goodbye.

Do nanoparticles have free access to cells? Is that why moderna is using Nanoparticles to deliver the mRNA into the cell? Question: is a virus itself also considered a nanoparticle? If so then why don’t they have free access into cells but need a lock and key mechanism to enter cells?

you the reson i passed all of gcses this year

[jabranqazi]

Sir plzzz explain that what is hybrid nanoparticles

[aachu]

What really happens at nano stage due to which property differs from bulk

This looks like Osmosis format lol, are they the same company?

Great Video. I did my PhD on nanoparticles.You explain well the different uses. Thank you!

[walidabuelsoud]

I still can not get it .. if we take about size and surface area then for exaample Ag atoms or ions are smaller than Ag nanoparticles !
