Numerous challenges exist in the high spatial characterization of organic filtration membranes and nanoparticle enhanced proteins used to augment photosynthesis processes using analytical electron microscopy (AEM) . In this work studies of polyamide layered membrane materials interdispersed with various elemental species have been investigated in order to understand both their initial compositions as well as changes which are intentionally introduced using atomic layer deposition (ALD) and sequential infiltration synthesis (SIS). These changes affect performance when such membranes are used in nanoscale filtration. Parallel studies of the limitations in characterization of nanoparticle enhanced photosystem II proteins will also be discussed.
