This paper explores the crystallization of glycine from aqueous solution within a variety of colloidalsystems in which the dimension of the crystallization environment varies from micrometers to nanometers. Thestudy focuses on the polymorphic outcome of crystallization experiments and the extent to which crystal size can becontrolled. The appearance of the 
and 
polymorphic forms is found to be related to the organization and functionalityof the surfactants utilized as well as the supersaturation. Overall, it is noted that while macroemulsions may beused to generate particulates of controlled size, crystal growth in microemulsion and lamellar phases is not restrictedto the dimensions of the aqueous domains.
