How to "Cap" Aluminia Membranes?

I am involved in nanobattery research and I am trying to find a way to
cover the pores of an anodic aluminia membrane with a conductive
surface. The problem is that these pores are only 60-70 nanometers
wide. Any one who knows anything about nanobatteries will understand
my problem. Currently the way that I am charging and discharging nano
batteries is to sputter graphite particle on to the electroyte filed
pores. However the sputtered particles are almost always a micron
wide. I need to either find a wasy to sputter smaller particles or
find a btter way to make idividual conductive particles over an
ordered anodic aluminia membrane.
If you have any ideas or know if this has been done before please
email me any information.
Thank you

Scientific wild ass guess time!
1) Do it by transfer. Lay down your conductive plane on a release layer or directly upon a thinned silicon membrane. Bond to your alumina. Pull off from the release layer or dissolve the few microns of silcon in caustic. Transfer works for microcircuitry.
2) Dope only the top edges or surface of the alumina grid with trace Pd(II) or Sn(II). Then electrolessly plate nickel, copper, silver...
3) Lay down a web of metallic single wall carbon nanotubes.

Just a thought but you'll have to look into a little on your own....
Electron deposition metalizing...possibly reverse the process and put your anode onto the carbon?

i don't know if this will be of any use to you as i am just starting work on 3d-psc. firstly have you considered colloidal particles? and secondly do you need the pores to be empty or can you fill with metal, if so i may have a possible technique you can try. have you also considered using a 3d-psc as an electrode as it would be self supporting and also is porous? if more information is required then contact me.
