Cellulosic nanomaterials have significantly promoted the development of sensing devices, drug delivery, and bioreactor processes. Their synthetic flexibility makes them a prominent choice for immobilizing biomolecules or cells. In this work, we developed a practical and user-friendly approach to accessing cellulose nanoparticles (CNPs).

The assessment of early atherosclerosis (AS) via fluorescence imaging is crucial for advancing early diagnosis research. Abnormal inflammation biomarkers, including hypochlorous acid (HClO) and viscosity within mitochondria, have been closely linked to the pathogenesis of AS. However, current fluorescent probes predominantly rely on unimodal imaging that targets a single biomarker and lacks mitochondrial specificity, which can result in potential false signal readouts due to the complex intracellular environment.

Background: Transthoracic echocardiography (TTE) is the primary modality for diagnosing aortic stenosis (AS), yet it requires skilled operators and can be resource-intensive. We developed and validated an artificial intelligence (AI)-based system for evaluating AS that is effective in both resource-limited and advanced settings.
Methods: We created a dual-pathway AI system for AS evaluation using a nationwide echocardiographic dataset (developmental dataset, n = 8427): 1) a deep learning (DL)-based AS continuum assessment algorithm using limited 2D TTE videos, and 2) automating conventional AS evaluation.
TiN Boosting the Oxygen Reduction Performance of Fe-N-C through the Relay-Catalyzing Mechanism for Metal-Air Batteries.

Metal-air batteries desire highly active, durable, and low-cost oxygen reduction catalysts to replace expensive platinum (Pt). The Fe-N-C catalyst is recognized as the most promising candidate for Pt; however, its durability is hindered by carbon corrosion, while activity is restricted due to limited oxygen for the reaction. Herein, TiN is creatively designed to be hybridized with Fe-N-C (TiN/Fe-N-C) to relieve carbon corrosion and absorb more oxygen when catalyzing oxygen reduction.

Flexible electronics have been rapidly advancing and have garnered significant interest in monitoring physiological activities and health conditions. However, flexible electronics are prone to detachment in humid environments, so developing human-friendly flexible electronic devices that can effectively monitor human movement under various aquatic conditions and function as flexible electrodes remains a significant challenge. Here, we report a strongly adherent, self-healing, and swelling-resistant conductive hydrogel formed by combining the dual synergistic effects of hydrogen bonding and dipole-dipole interactions.
