dear listers:
when quantum dots appeared I remember hearing a talk from the original 
company, and in their portfolio there would QD's with strong negative 
and positive charges, to allow different coatings. We are now 
considering options for these coatings, but I cannot track specifically 
th einfo regarding the different surface charges. This occurred some 
time ago, and I may be mixing up things, but if anyone has any hint, 
advise, or experience, I would be most grateful.

Kind regards
Jose
