There are several, here is one: http://www.freshpatents.com/Silver-halide-photographic-light-sensitive-material-dt20041014ptan20040202974.php
[0199] Furthermore, a development method where the coated silver amount of the light-sensitive material is reduced and a treatment for amplifying the image (intensification treatment) using hydrogen peroxide is performed, is also preferably used. More specifically, an image formation method using an activator solution containing hydrogen peroxide is preferred and this is described in JP-A-8-297354 and JP-A-9-152695. Apparently, it acts more as an enhancement for development than for development. So it would enhance the development or reduction process in the blood stream. Don't forget for reduction the solution must be basic, like the blood. You may try adding some sodium hydroxide to the solution and see if it will reduce that way. But without another developer present it may be slow or non-existant.
