Dear all,
What is the best solvent or buffer for pi-pi interaction of CNT?
Low polarity solvent is good for non covalent conjugation?
I wonder that...
Thank you.
I think that will suit n-hydrocarbon, such as dodecane. He will respond pi - CH bond to the aromatic molecule and with SNT. See the link address https://www.princeton.edu/chemistry/macmillan/group-meetings/cation%20pi.pdf
Dear all, I use hydrophobic or insoluble drug for injection What is proper solvent that is low cytotoxicity ?
