Example apparatuses and systems are disclosed for providing controlled delivery of electrolysis products to a site which may be used the treatment of infection and ablation of undesirable cells and tissue. A system disclosed may include a power supply, two electrodes, an aqueous matrix that may close the electric circuit between the electrodes at the treated site and a controller. The controller may control the electrical circuit to induce a direct current through the electrodes and an aqueous matrix to produce electrolysis products. The duration and magnitude of the charge applied may determine the dose of the products applied to the treatment site. The composition of the electrodes and the aqueous matrix may be chosen to produce desired products. An apparatus is disclosed that may be in the form of a pad for applying to a wound. An apparatus is disclosed that may be used for treating internal tissue.
