selective for the best receptor when only modest amounts of guest are used. In contrast, the correlation between guest binding and the extent of amplification of a given receptor across a wide range of guests tends to be poorer, because every guest has its own unique set of affinities for competing receptors in the DCL. This implies that the results of screening a DCL for selective receptors by comparing the

Few methods currently exist for controlling vesicle–vesicle adhesion. We now report a new system, based upon a multivalent guest and an amphiphilic receptor with a photo-isomerisable anchor that can be incorporated into lipid vesicles of different sizes. Large unilamellar vesicles containing our receptor were found to aggregate upon addition of the multivalent guest, independently of photoswitching between the two conformations of the anchor. However, for giant vesicles immobilised on a platinum wire, guest-mediated adhesion only occurred upon photo-isomerisation of the anchor. This behaviour was attributed to the dynamics introduced into the system through the conformational changes caused by irradiation.
