Thermostable Bioluminescent Intercalating Dyes for Real‐Time, Integrated Nucleic Acid Amplification and Detection

Angewandte Chemie, EarlyView.
We present a bioluminescent diagnostic platform that integrates DNA amplification and detection in a single step. The engineering of thermostable luciferase‐intercalating dye conjugates and controlled release of caged luciferin substrates enable real‐time, detection of attomolar concentrations of viral DNA within 30 min.

Time‐Multiplexed Organic Electrochemical Transistor for Saliva‐Based Rapid Detection of Viral Proteins

Advanced Science, EarlyView.
A time‐multiplexed nanobody‐functionalized organic electrochemical transistor enables rapid and sensitive detection of three respiratory viral proteins from saliva. Sequentially addressed multi‐gate electrodes on a shared channel achieve around 1 fm detection within 15 min without sample preprocessing. Clinical validation demonstrates high specificity,

Machine‐Learning Microfluidic Minute‐Scale Microorganism Metrics Monitoring(M6)

Advanced Science, EarlyView.
ABSTRACT On‐site monitoring of microorganisms remains challenging because of low concentrations, strong background interference, and dynamic aerosol diffusion, particularly for aerosol‐transmitted pathogens. Here, we report a rapid detection platform that integrates a Puri‐focusing microfluidic chip, electrochemical impedance spectroscopy (EIS), and ...
