Normally the aggregation may not aggregate.. The protein has negative charge so the nanoparticles repel each other. The clean glass carbon maybe has some remain acid from washing (h2so4, HNO3) which cause protonization of protein.

Gold nanoparticles decorated poly-melamine modified glassy carbon ?

Melamine transfers to poly-melamine in your system ?

Dear sir

actually we prepared melamine capped AuNPs, but it may any chance to convert melamine to poly-melamine? if yes, how we known that it's melamine or poly-melamine?
