Gas sensing is vital for ecological protection in agriculture, early disease diagnosis biomedicine, and safety industrial production. Covalent organic frameworks (COFs), a new class of porous polymer materials, can be customized through specific ligand selection to tailor pore sizes active sites, enabling them selectively enrich interact with targeted gas molecules, making promising candidates sensing. To advance their use this field, it essential investigate the mechanisms complex interactions between COFs target molecules as well improve COF film fabrication methods. This review outlines design strategies films across multiscale: molecular interaction mechanisms, macroscopic interfacial synthesis methods, microscale/nanoscale approaches such double-layer filtration micro/nanostructured improved transfer. Finally, several key research directions are proposed suitability COF-based materials environments.

Developing sensitive sensors to trimethylamine (TMA) remains a topic of great interest in areas such as food quality analysis and disease biomarkers. To address this issue, chemiresistive were proposed using graphene quantum dots (GQDs) with different proportions hydroxyl (GQDs-OH), epoxy (GQDs-epoxy), carboxyl (GQDs-COOH) groups. These materials exhibited sensitivities TMA, GQDs-OH being the most sensitive, presenting detection limit 0.3 ppm response about 4 2.5 times higher than those GQDs-COOH GQDs-Epoxy, respectively. This difference sensitivity was elucidated by building, based on density functional theory calculations, potential energy curves interaction between TMA three GQD models. Noncovalent atoms molecular also used explain each model. Our results highlight that proportion oxygen groups has major role modulating against group providing greater sensitivity. through computational simulations, which explained lower other materials. work serves practical guide, demonstrating importance coupling experimental methods achieve deeper understanding sensing results.

With the goal of impacting patient quality life and outcomes, sensor science offers significant potential to revolutionize healthcare by providing advances in detection molecular biomarkers for personalized clinical technologies. The community has achieved technical advancements that can impact diagnostics, health monitoring, disease treatment; however, many innovations remain confined laboratory, failing bridge translational gap between research real-world applications. This perspective presents a new direction community, where development centers on needs experiences primary beneficiaries: patients. We provide guidelines resources researchers engage with patients early continuously throughout process inform specifications better align technologies needs, improving their adoption impact. also present examples implementing patient-centered approach planning engagement research. In design impactful sensors patients, must expand focus beyond embrace approach, which will likely lead opportunities collaboration evolution community.
