Tuning the size of silver deposits by templated electrodeposition using agarose gels

Tuning the size of electrochemically deposited silver crystals is possible by using template layers of agarose gels of certain concentrations on platinum electrodes. The size of the silver crystals can be controlled in the range of 100 to 400 nm by choosing the appropriate agarose concentration. The obtained crystal sizes match very well with the size of the pores that have been reported in literature for the used agarose concentrations. This is also a good proof of the correctness of the earlier pore-size estimations applying other techniques.
