How can I deposit micro and nano (100nm--) particles on a surface, just like the dust on the surface?
You need to clarify your question for what purpose you like to sprinkle your NPs, What sort of NPs you like to disperse on what sort of surface. If you have weakly agglomerated NPs in powder form, just sprinkle them on the adhesive surface and tap on table to remove extra particle you can get and good coating on NPs on the surface as we usually do for sample preparation for SEM/AFM.
Thanks Dr. Habib. I just want to develop a method to sprinkle some particles on various substrate with controllable thickness. As you say, the particles are weakly agglomerated and in powder form.
The higher the surface area the better capapility to catch dust, you need to use h. Surface area
