I have a metal (Silver) Hole Array (thickness 200nm) with the Hole radius about 200nm. Also, I have non-magnetic (Pd) nanoparticles dissolved in the solvent (hexane). Is there any way to put the nanoparticles into the Hole?
Thank you very much!
Minh Pham What is either size of the hole? What is the material around the hole made of? Is it pure silver with holes? Have you looked at the surface with ESCA/XPS as the surface functionality is key?

What do you mean when you use the term "dissolved"? Does this mean that you have a solution of metal (Pd) in an organic solvent (hexane)? Who produces this miracle? You also claim that this palladium is non-magnetic. Mean it that magnetic one known?
If seriously, you can try use this silver array as filter (may be under pressure difference). Hole (200 nm) is enougth for hexane molecule passing.
You can try to use the "scrape" method. Just spread the solution on the surface and use soft film to scrape the solution along the surface. The NPs will be trapped in the hole and NPs on the surface will be scraped away. I remember that this method was used in some papers and the NPs were successfully trapped in the holes. You can have a search of this method.
Gold nanohole array to trap single polystyrene nanoparticles, with a mean diameter of 30 nm, into separated hot spots located at connecting nanoslot regions. This plasmonic array is useful for lab-on-a-chip applications and has particular appeal for trapping multiple nanoparticles with predefined separations or arranged in patterns in order to study interactions between them.
