Professor Alexandridis' research aims to create and manipulate molecular organization at the nano-scale and organization at the micron-scale of nano-objects via (a) the self-assembly of amphiphiles in a variety of conformations and length-scales, and/or (b) the use of prescribed external fields to direct macromolecules, assemblies, and/or particles.

Amphiphiles such as block copolymers, surfactants, lipids and proteins, posses moieties with an affinity for different environments. This molecular design enables amphiphiles to spontaneously organize: self-assembly. Self-assembly is an energy-efficient process that leads to functional, high value-added products with desired compartmentalization, compatibilization, rheological, and interfacial properties. Nano-scale objects resulting from self-assembly or (bio)synthesis (e.g., cells, nanoparticles) can be organized over larger length-scales, often in a hierarchical fashion, via the application of external fields (flow, electric): directed assembly.
