Ultrasensitive Nanofluidic Detection of 17β-Estradiol in Natural Water by DNA Circuit-Mediated Hyperbranched DNA Nanowire Dual-Signal Amplification
{{output}}
The pervasive detection of trace 17β-estradiol (E2) in aquatic ecosystems necessitates innovative analytical platforms capable of ultrahigh sensitivity and field applicability. Herein, we report a nanofluidic biosensor integrating polydopamine-functionalized ... ...
