Thiolated aptamer is the most common one I'v ever seen.

Thank you.

Thiolated aptamer method is well reported, not only on gold nanoparticles, but also on other gold related surface like gold-coated glass. There should not be a problem using thiolated aptamer method at least in term of immobilization.

Thank you Yubin.
