Abstract
The crystallization boundaries of small, attractive particles are found to be identical when interactions are modeled as adhesive hard spheres. Based on experimental results and the attraction range, we conclude that solubility is insensitive to interaction details and various colloidal particles will only display equilibrium colloidal fluid and colloidal crystal equilibrium phases. This study provides a basis for the observations of George and Wilson [Acta Crystallogr. D 50, 361 (1994)] who suggest using second virial coefficient measurements to identify protein crystallization conditions.Keywords
