Abstract Gas‐phase water molecule sensors are essential in scientific, industrial, and environmental applications, playing a crucial role ensuring human safety, monitoring pollution, optimizing processes. However, developing gas‐phase with high sensitivity remains significant challenge. Herein, the effect of molecular adsorption on capacitive response is explored, facile surface engineering strategy to achieve sensitive carbon nanodots (CDs)‐based for H 2 O demonstrated.hydrophilic raw precursor utilized prepare hydrophilic CDs further employ these as active media sensors, demonstrating how influences molecules. By applying engineering, affinity potential regulated, resulting that exhibit broad detection range from 11% 98% relative humidity (RH), remarkable 3.3 × 10 5 pF/RH an impressive 1.8 8 % at RH. These CDs‐based present great applications respiratory monitoring, information exchange, contactless recognition finger trajectories, etc. The findings unveil unique influence response, opening new avenues design highly sensors.

Abstract In vivo monitoring of biological compounds and xenobiotic substances is essential to deeply understand their mechanisms functions within living subjects. However, there are many challenges impeding the development these technologies, typically including complexity environment, detection limit substance, stability short‐ long‐term sensing. Recently, carbon nanomaterials have been synthesized, investigated, applied in electrochemical optical sensors assist this endeavor. This review provides up‐to‐date information about major (e.g., graphene, graphene oxide/reduced oxide, nanotubes, fibers, CDs) used photochemical First, properties synthesis methods briefly discussed. Then, based on nanomaterials, fabrication applications microdialysis, microelectrodes, microneedles) (fluorescence, visualization, bioimaging) discussed detail. Finally, perspectives further advance application nanocomposites provide a reference source for future research developing biocompatible vivo, leading creation more efficient reliable high‐throughput monitoring.

Amphiphilic Carbon Dots for Ultrafast and Wash-Free Mitochondria-Targeted Imaging

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Май 18, 2025

Carbon dots (CDs) exhibit exceptional biocompatibility and programmable amphiphilicity, establishing them as transformative nanomaterials for subcellular visualization with resolution. However, existing CD-based probes lack the spatiotemporal precision required real-time organelle tracking, particularly in mitochondrial-targeted imaging via ultrafast, wash-free protocols. To overcome these limitations, this study describes solvent-free, high-temperature (280 °C) short-time (2 h) preparation of green-emitting CDs (GCDs) distinctive amphiphilic architectures utilizing benzoylurea citric acid a sealed high-pressure reactor. GCDs may form micelle-like structures driven to hydrophobic interactions, producing long-wavelength emission contrast blue low-polar solvents. They also simultaneously activate synergy numerous endocytotic modes, achieving ultrafast (<5 s) imaging. can effectively target mitochondria, more significantly, both normal cancer cells (Person's value ≈ 0.90/0.91), which is explained by minor adjustment mitochondrial membrane potential. This work assembly mechanisms while potential design principles mitochondria-targeted nanostructures wash-free, tracking.
