Gold plasmonic nanostructures with high sensitivity and spectral reproducibility are key components of molecular sensors based on surface‐enhanced Raman scattering (SERS). In this paper, we report a “bottom‐up” fabrication of gold “film over nanosphere” (FON) substrates for SERS sensing on the basis of very small (107 nm in diameter) polystyrene spheres coated with 20 nm of gold. To obtain close‐packed...
Structured diamond films are required for several uses as photonic crystals, (bio‐) sensors, biomedicine, etc. Often, these uses require fabrication of nano‐sized features with the assistance of lithographic techniques. In this paper, we demonstrate the growth of diamond structures well ordered in periodic arrays. The technological process starts with ultrasonic seeding of Si substrates by ultra‐dispersed...
