As the title says, Is there a simple and efficient way to measure the potential of zero charge of a SAM coat-electrode?
Dear Kamyar Khoshnevisan ,
Thank you very much for you reply. I will check the methods you suppose. By the way, Can we measure it by electrochemical way?
As I say in the title, except the fluorescence label and mutant methods, is there any other method to identify the orientation of a specific protein on lipid membranes ?
