Background and Introduction

Microscale colloids with anisotropic morphologies have proven useful to the development of novel materials and fluids for optical, biomedical, and self-assembly applications. At Harvard University, researchers in Professor Weitz's research group are bestowing anisotropic colloids with Janus-like chemical functionalities to create "colloidal surfactants."

A brief summary of the article cited above is presented along with some demonstrations of the surfactant-like properties of the anisotropic colloids developed by in Professor Weitz's lab.
