A dual-analyte probe: hypoxia activated nitric oxide detection with phototriggered drug release ability.

A new strategy for the detection of hypoxia and NO succeeded by photocontrolled delivery of an anticancer agent has been demonstrated. The developed system is able to produce distinct responses (dual channel) upon interaction with hypoxia and NO. This probe can also release anticancer drugs upon photoirradiation acting potentially as both a dual-analyte imaging agent and a prodrug.
