Evaporation‐Enhanced Redox Cycling for Rapid Detection of Attomolar SARS‐CoV‐2 Virions Using Nanolithography‐Free Electrochemical Devices

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents microfabricated electrochemical sensors for detecting ultralow viral particles counts through evaporation‐enhanced redox cycling (E2RC). To achieve sub‐micrometer gap in interdigitated microelectrodes, a scalable, nanolithography‐free fabrication method is developed.

Streamlined Inkjet‐Printing of Stretchable Organic Photodetectors

open access: yesAdvanced Materials Technologies, EarlyView.
This work introduces stretchable photodetectors fully inkjet‐printed on stretchable substrates. It is demonstrated that printed stiff platforms effectively decouple strain from the stretched substrate and serve as a chemically resistant and mechanically rigid platform.
