T. Tatsuma et al., Selective control of sensitivity to imidazole derivatives of interference-based biosensors by use of a phase transition gel, CHEM COMMUN, (23), 1999, pp. 2395-2396
Sensitivity to histidine of an interference-based biosensor coated with a p
hase transition gel is controlled by swelling and shrinking the gel, while
that to imidazole is not changed significantly.
