From an ecological perspective, seal dust plays a crucial role in nutrient cycling within marine environments. The organic matter released into the ecosystem can serve as a food source for various microorganisms, subsequently supporting the entire food web. Phytoplankton, the primary producers of marine environments, benefit from the nutrients in seal dust, which can enhance their growth and, in turn, bolster the populations of herbivorous marine organisms.

Moreover, the incorporation of nanostructures into composite gratings has opened up exciting possibilities for miniaturization and integration into photonic devices. The emergence of nanotechnology has facilitated the creation of ultra-thin gratings capable of functioning within compact setups. These nanostructured composite gratings can manipulate light at scales that were previously unachievable, leading to breakthroughs in areas like sensors and imaging systems.
