Self Assembly in Fluid Media

Examples of self-assembly in a liquid, or in a dense-gas (supercritical fluid) phase, medium are the following:

(i) Self-assembly of polymerizable amphiphiles [3,4,32-34], polymer and lipid utilization to form ordered aggregates. Such ordered aggregates can be in the forms of monolayers, bilayers, micelles, micelle-coacervates (Figure 10) or nanoparticles.

(ii) Fluidic self-assembly using a template surface and employing liquid stream to select appropriate components, is another approach [1]. Figure 11 illustrates the general procedure in fluidic self-assembly.

(iii) Dynamic combinatorial libraries (DCLs) which have an outstanding position in the combinatorial chemistry, as it will be presented in Chapter 10.
