I think that antibodies have a lot of therapeutic potential particularly because of their ability to be very readily modified to enhance the functions even further. I’m not too sure how big the difference in stability for antibodies and nanobodies are but from what I have read it’s quite a substantial difference. Nanobodies are also supposedly easier to produce, I suppose this would be true for chemically synthesized antibodies versus nanobodies.
Antibodies are the highest if not one of the highest kinds of drugs that is being approved right now so the market for antibodies is very high valued. Personally, Id like to explore if there’s more ways to modify the antibody to improve delivery to its specific target site.
