Label‐Free, Sensitive, and Direct Detection of Cardiac Troponin Biomarkers Using Frequency‐Locked Microring Resonators

open access: yesAdvanced Sensor Research, EarlyView.
A deployable, chip‐integrated approach to the detection of heart attack biomarkers is demonstrated using silicon photonic microring resonators combined with microfluidics. By applying the Pound–Drever–Hall frequency locking technique, sensor signals are measured with improved signal‐to‐noise ratio, applying this to real‐time, selective readouts.

Compact Multichannel Plasmonic Device for Rapid and Versatile Inflammatory Biomarker Analysis

open access: yesAdvanced Sensor Research, EarlyView.
A multichannel plasmonic biosensor has been developed for the simultaneous detection of up to four inflammatory biomarkers relevant to sepsis diagnostics. Its performance has been optimized, and analytical validation has been conducted for the detection in diluted serum, highlighting its potential for clinical applications.

Evaluation of Absorbent Solutions for the Integrated CO2 Desorption and Electrolysis

open access: yesAdvanced Sustainable Systems, EarlyView.
Integrated CO2 electrolysis combines desorption and electrolysis to reduce costs and emissions. This study identifies KOH and piperazine as effective absorbents, providing sufficient electrochemically accessible CO2 and compatibility with cell conditions.
