NSL—often called colloidal lithography (CL)— is an effective technique using self-assemblies of polystyrene (PS) micro- or nano-particles on solid surfaces as 2-or 3-dimensional masks for metal deposition (Zhang et al. 2010). The size and shapes of the close-packed nanospheres and the holes between them, in addition to the metal deposition conditions, such as evaporation angle or specific deposition technique (e.g., sputtering, thermal deposition), influence the achieved metallic patterns. A different kinds of metallic nanostructures can he obtained (Fig. 3.10) ... 

In order to investigate this effect, ordered arrays of metallic nano-islands were fabricated on glass substrates by a process of natural lithography using monodisperse polystyrene nanospheres. The metal particle dimensions were tailored in order to tune the plasmon resonance wavelength to match the spectral absorption of the fluorophore. The fluorophore, Cy5 dye, which is widely used in optical immunoassays and has a medium quantum efficiency ( 0.3), was used in this preliminary study of the plasmonic enhancement effect.

It was also reported that HCP networks can be used as stabilizers to produce metal nanoparticles. A hyper-crosslinked polystyrene network (HPS), obtained from a styrene-divinylbenzene copolymer, acts as a matrix to synthesize Co nanoparticles owing to its nano-sized rigid cavities of comparable size. These cavities ean eonsume several Co eomplexes and can control the growth, particle size and size distribution of Co nanopartieles. ...
