You can find help in the article:

wish you all the best !

you have to have a NPs with the amine or carboxylic group or SH group  in order to bind an AB or peptide to it

I agree with Pf. Shanehsazzadeh. You need those gruops in order to link with the drug. You can use the carbodiimide chemistry (for example EDC+NHS).
