Does have centrifuging or sonicating any effect on covalent bond between thiol and gold nanoparticle ?

29 June 2022 0 9K Report

I added mercapto propanoic acid to gold nano particle with 400nm and one drop HCl. the solution change from pink color to completely clear, even after sonication. Then I did Centrifuge. after that all gold particle get together again. I want to know sonication or centrifuging does have effect on covalent bond or not?
