This video https://youtube.com/watch?v=0EokkhdppgE describes quantum dots as small semiconductors that change the color of a substance?
1) How does this work? The video shows this diagram (see attachment), but I don't understand it. What is meant by 'energy', potential energy of something? What are the 'bands'? I think the quantum dot is changing the size of the 'band gap', but how is it doing this?
2) This article, https://ncbi.nlm.nih.gov/pmc/articles/PMC8395193/ as will as many others mention quantum dots applications for gene therapy. How exactly to quantum dots target specific organs?
Many thanks in advanced!
The link to the article is dead.
My bad, does this work:
The name of the article is "Nanotechnology-Based Strategies to Overcome Current Barriers in Gene Delivery".
The papier you shared is only a summary of nanotechnology that can be used for gene therapy, the one explaining the quantum dots are:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6642839/ (this seams to have a simple explanation)
The new ones: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7537666/
They are fascinating tech , for my interest especially, the probes for real-time identification of disease-relevant biomolecules.
This seams to be the latest summary of the current solutions and obstacles: https://pubmed.ncbi.nlm.nih.gov/34445243/
Having been in the quantum dots just for screens, I can tell you that stuff is super expensive, we are talking of equipment in the ten of Millions.
