An Artificial Riboflavin Receptor Prepared by a Template Analogue Imprinting Strategy

Cheers! Specificity for riboflavin in water-rich media with an affinity on the order found for the corresponding biological receptor, riboflavin binding protein, is shown by a receptor containing a complementary hydrogen bonding array (see picture). Microcalorimetry performed at low receptor concentrations in a solution mimicking an alcoholic beverage indicated the presence of a small but uniform population of high-affinity sites (K>106 M−1).
