Abstract:
A dual-diagnostic system of endom-icroscope and microneedle sensor is developed to demonstrate high-resolution imaging combined with electrical real-time detection of NO released from cancer tissues. The dual-diagnostic system can be a new platform for facile, precise, rapid, and accurate detection of cancers in various biomedical applications.
