Recently I am doing drug uptaking experiments. I put the swollen hydrogels
into the drug solution. At different time intervals I take out some drug
solution, and dilute them to detect the concentration by HPLC. First I thought
this way is good to determine the drug uptaking kinetics. However the results
are not good because the concentration of the solution didn't change very
much.
Can you tell me how to d
