1. A nanotextured material comprising:
a substrate having a plurality of nanopillars extending there from and having a density of between 2 and 20 pillars per micrometer squared, at least a portion of the plurality of nanopillars being functionalized with silane chemistry;
each of the plurality of nanopillars having a narrowed tip opposite the substrate, each nanopillar tip having a tip angle of 20° to 10° and a length of between 400 nm and 10 μm, with an aspect ratio of 14-16, each nanopillar tip comprising from 18% to 50% of the length for each respective one of the plurality of nanopillars; and
the plurality of nanopillars forming clusters, each cluster comprising at least two nanopillars.
