The caption of Fig. 3 is incorrect. The caption should read as follows:

Fig. 3 UV-Vis spectra recorded in water–ethanol (70 : 30, v/v) of: avidin (~6 x 10^-4 M) + 2 (~6 x 10^-5 M) (grey line); avidin (~6 x 10^-4 M) + 2 (~6 x 10^-5 M) + 1 (~6 x 10^-5 M) (purple line); avidin (~6 x 10^-4 M) + 2 (~6 x 10^-5 M) + 1 (~6 x 10^-5 M) + 4 (~2 x 10^-4 M) (green line).

The Royal Society of Chemistry apologises for this error and any consequent inconvenience to authors and readers.
