Dear ResearchGate members,
I would like to know if polymers such as Polyvinyl alcohol, Polyvinyl pyrrolidone, Chitosan, Carboxymethyl cellulose, etc. (with a molecular weight less than 40 kDa) have a lambda max in UV-Vis spectroscopy. If they do, how do they not interfere with drug estimation in nanoformulations/nanoparticles (polymer-based nano)?
Thanks in advance.
