Is there any simulation protocol or paper which can simulate the dynamics of drug entry and interaction with the target protein?
This is a tough topic, have a look at the following references and see, if they can help you:
Absolutely, the two I've had the most success are working with a radiolabeled and a fluorescently labeled version of the drug. Many drugs autofluoresce as well and this can be easily tracked.
When it's labeled as mentioned above microscopy or a luminometer, spectrophomoter or a scintillation counter can evaluate fractions or whole cells, or purified binding substrates.
