Photoelectrochemical Nanofiber Ferritin Sensor with Integrated “Migrating‐Destructing‐Detecting” Capability (Adv. Funct. Mater. 7/2026)

Photoelectrochemical Nanofiber Ferritin Sensors In their Research Article (10.1002/adfm.202518124), Xiaotong Zheng and co-workers present an ultrasensitive photoelectrochemical nanofiber ferritin sensor with integrated migrating-destructing-detecting nanoreactors. The linear range of ferritin detection is from 10−8 to 102 mg/mL and the minimum detection limit reaches 5 pg/mL. An iron ion signal enhanced response device is explored to achieve rapid and precise monitoring of ferritin levels in different pathological states.
