Colloidal clustering in an evaporating aqueous droplet was investigated by means of optical microscopy. The colloids were negatively charged paramagnetic polystyrene microspheres coated with a monolayer of the protein streptavidin. The dynamical process of the colloidal clustering was characterized...
