Abstract
, short response time (∼1 s), and low limit of detection (1.82 mM). Because of the encapsulation of GA, good water and pH stability, and anti-interference performance are observed for the GA-capped PNC-based fluorescence sensor. Our findings provide an insight into the biosensor applications of hydrophilic PNCs.
