Hi, Niklas,

I suggest our Qdot quantum dots, from Thermo Fisher Scientific.  We have them with emission ranges from 525 up to 800, with size ranges between 13-21 nm hydrodynamic diameter (the farther red-shifted the product, the larger the diameter).  They are very bright and photostable, and we have many different derivations for different uses or conjugations.

A 456 nm laser line will excite all of them very efficiently.

Please feel free to reach out to me if you wish for more information (I have a sizing chart I can send you, for instance).  Here is our general landing page for information:  www.thermofisher.com/qdot

And here as well:  http://www.thermofisher.com/us/en/home/brands/molecular-probes/key-molecular-probes-products/qdot/technology-overview.html

Cheers,

Jason

Dear all,

I am looking for stable and bright quantum dots in the size range 3 to 20 nm. We have laser lines accessible in the range 456 nm to 635 nm. I would be happy for any advice about where to find such quantum dots (or other very bright particles) in that size range.

Best regards
Niklas Lorén
