Fig. 3: Deposition nanogel on fabricated nanopillars.

a The effect of the level of Au deposition on the formation of leaning nanopillars. A representative image of three individual experiments is shown (scale bar: 100 nm). b The importance of Au-thiol interactions for affixing leaning nanopillars on nanogels. A representative image of three individual experiments is shown (scale bar: 100 nm). c The importance of the gap between nanopillars and the deposition of nanogel shows no significant disruption to the electromagnetic wave of nanopillars.
