[83][84] are particularly fascinating, because they combine multivalency with the ability of a molecular device to respond to external stimuli, in

• this approach. With our toolbox, the number and position of binding sites can be varied systematically; hence, the toolbox provides a means to examine multivalency. However, despite the fact that there is qualitative evidence for pseudorotaxane formation, the binding motif is not yet optimal for a

• fimbriated bacteria, respectively [13][14], multivalency effects were observed in many cases. In addition, concentration-dependent inhibitory and stimulating allosteric effects on adhesion have also been reported with certain carbohydrate ligands [15], which might be explained by the existence of allosteric

Examples of such a versatile approach are also
