Query: Quantifying the structural integrity of nanorod arrays   Arrays of aligned nanorods oriented perpendicular to a support, which are
accessible by top-down lithography or by means of shape-defining hard
templates, have received increasing interest as sensor components, components
for nanophotonics and nanoelectronics, substrates for tissue engineering,
sur-faces having specific adhesive or antiadhesive properties and as surfaces
with customized wettability. Agglomeration of the nanorods deteriorates the
performance of components based on nanorod arrays. A comprehensive body of
literature deals with mechanical failure mechanisms of nanorods and design
criteria for mechanically stable nanorod arrays. However, the structural
integrity of nanorod arrays is commonly evaluated only visually and
qualitatively. We use real-space analysis of microscopic images to quantify the
fraction of condensed nanorods in nanorod arrays. We suggest the number of
array elements apparent in the micrographs divided by the number of array
elements a defect-free array would contain in the same area, referred to as
integrity fraction, as a measure of structural array integrity. Reproducible
procedures to determine the imaged number of array elements are introduced.
Thus, quantitative comparisons of different nanorod arrays, or of one nanorod
array at different stages of its use, are possible. Structural integrities of
identical nanorod arrays differing only in the length of the nanorods are
exemplarily analyzed.
