Intrinsically Soft Implantable Electronics for Long‐term Biosensing Applications

open access: yesAdvanced Sensor Research, Volume 4, Issue 7, July 2025.
Intrinsically soft implantable biosensors address the mechanical mismatch of conventional rigid implants, improving biocompatibility and stability. This review explores soft encapsulation matrices, stretchable conductors, implantation strategies, and chronic fixation techniques.

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.

Cost‐Effective Hierarchical Cobalt Nanostructured Laser‐Induced Graphene for Enhanced Uric Acid Detection

open access: yesAdvanced Sensor Research, Volume 4, Issue 7, July 2025.
A one‐step electrochemical strategy is utilized to develop a flexible, enzyme‐free biosensor for the sensitive detection of uric acid (UA). The hierarchical cobalt nanostructures synergistically enhance the performance of the biosensor, resulting in a broad detection range of 5 to 700 µM with a sensitivity of 6.75 µA µM−1 cm−2 and a low detection limit

Anisotropic Surface Microrollers for Endovascular Navigation: A Computational Analysis with a Case Study in Hepatic Perfusion

open access: yesAdvanced Theory and Simulations, EarlyView.
Computational fluid dynamics analyses assess the upstream locomotion performance of anisotropic microrollers with varying height‐to‐width ratios. Observing their successful upstream locomotion in veins, their performance in hepatic circulation is investigated for treating primary liver cancer.

Loss of NR2F6 Protects from Salmonella Typhimurium Infection

open access: yesAdvanced Science, EarlyView.
Loss of nuclear receptor NR2F6 reduces tissue‐resident macrophage populations. Nr2f6‐deficient mice are protected from weight loss and bacterial load during infection with Salmonella Typhimurium. Pro‐inflammatory cytokines and iron levels are altered in infected Nr2f6‐deficient mice.
