Simultaneous analyte indicator binding assay (SBA) for the monitoring of reversible host-guest complexation kinetics

Chem Commun (Camb). 2021 Nov 25;57(94):12663-12666. doi: 10.1039/d1cc04888k.

Abstract

Very little information is available on the kinetics of the self-assembly and dissociation of optically silent building blocks despite the importance of such data in the rational design of tailor-made host-guest systems. We introduce here a novel time-resolved method that enables the simultaneous determination of complex formation and complex dissociation rate constants for inclusion-type host-guest complexes. The simultaneous analyte indicator binding assay (SBA) gives also direct access to binding affinities, thus largely simplifying the experimental procedure for a full kinetic and thermodynamic characterisation of host-guest systems.
