The Advanced Colloids Experiment-Nanoparticle Haloing (ACE-T-12) involves design and assembly of complex three-dimensional (3D) structures from colloids, or particles of different sizes suspended in a fluid. It employs a recently discovered technique, Nanoparticle Haloing (NPH), which uses highly charged nanoparticles to stabilize much larger, non-charged particles. Allowing these structures to form in microgravity provides insight into the relationship between shape, surface charge, and concentration of particles and particle interactions.
