Micellar Nanolithography A Versatile Technique for Designing Nanopatterned Surfaces 88... 

Particularly in 2D systems, control over the self-assembly of colloidal templates has offered a versatile way to produce patterned surfaces or arrays with a precision of few nanometres. Diblock copolymer micellar nanolithography (dBCML) is a versatile method that uses homopolymers or block copolymers for the production of complex surface structures with nanosized features [69], In contrast to other approaches like electron-beam lithography (EBL) and photolithography, dBCML does not require extensive equipment. In fact, it is commonly used in the fabrication of data storage devices and photonic crystals, in catalyses [70], and for the design of mesoporous films and nanoparticle arrays [71]. 

In selected cases, it is desired to pattern the nanoparticles into nanoarrays rather than to arrange them into a continuous film. Polleux et al. reported the synthesis of titania nanoparticles and their arrangement in one step by combining the benzyl alcohol route with micellar nanolithography [196]. TiClj dissolved in benzyl alcohol in the presence of a diblock copolymer was aged and dip coated, upon which different titania nanoparticle patterns formed, ranging from quasi-hexagonally ordered nanodots to curved and parallel oriented nanowires.
