@Kanchan Sonam has asked me this question as a response to his earlier question that was posted in the public RG forum. I was PM'd which means that others on RG cannot benefit from any other answers from the RG community:
Respected Sir,
First of all thank you for your suggestion. But sir i have to prepare Salinomycin nanoparticle (AuNP). I am unable to get any procedure who do not use PEG in the protocol. instead of PEG i want to use some another polymer . As you Suggest to use PEI . Sir my query is that PEI will interact with Salinomycin or not , because my main aim is to prepare Sal - GNP? waiting for your kind reply . Thank you.
