✦ Synopsis

The process of condensation of an amorphous solid into a rigid matrix can often trap molecules in reversible binding sites. Exchange of the same molecular species with such sites is known to be sensitive to small chemical differences and to distinguish between enantiomers. In addition to their usefulness in chromatographic processes, such materials can separate, by solid phase extraction, specific compounds from complex mixtures. Furthermore, the trapped molecules can have their reactions guided and catalytically changed. The combination of this spontaneously formed system of templates and catalytic sites may support a type of replication cycle, and suggests some pathways from simple chemistry toward the complexities of biology.
