The use of polymers is finding a significant place in development sensors. Better selectivity and rapid measurements have been achieved by replacing classical sensor materials with functions polymers. Several receptors employed to detect glucose fluorescence sensors, these include enzymes such as oxidase, dehydrogenase hexokinase/glucokinase, bacterial glucose-binding protein, boronic acid derivatives. Boronic has important role the design sensing membrane was prepared...
