High resolution nanofiber example

When transfer of nanofibers is unavoidable, molecule affinities play a large role. For example, the Pt necklaces in Figure 9.15a spread out beautifully on the carbon support film, but were attracted to the carbon too much to allow themselves to be draped over holes in the support film and thus allow high-resolution TEM (HRTEM) imaging without the intervening support. If deposited near a hole, the necklace particles instead pile up on the carbon film.
