“…In recent years, more attention has been devoted to the field of colorimetric applications of PC sensors owing to their merits of nonfading, easy-to-operate, and unique optical modulation properties . PC sensors have demonstrated utility in detecting glucose, , DNA, , protein, , H 2 O 2 , , temperature, − and other signals. Since uricase can oxidize uric acid to H 2 O 2 , − it is expected that H 2 O 2 -responsive redox PC sensors will be used for uric acid detection.…”
