As a marker molecule in respiratory gases for the pulmonary disease asthma, nitric oxide (NO) has attracted much attention real-time gas monitoring. However, low sensitivity, poor selectivity, and high operating temperature limit practical applications of metal semiconductor (MOS) based chemiresistor sensors. Herein, by deliberately introducing metal-organic frameworks (MOFs) free-standing TiO2 nanochannels (NCs), sensor with excellent detection ability outstanding selective traits is developed sensing NO at room (RT). The precisely engineered Cu(II)-based MOF Cu-TCA (H3TCA = tricarboxytriphenyl amine) induces more active surface NCs, causing buildup CuTCA/TiO2 p-n heterojunctions that improve response RT just via simple UV irradiation (λ 365 nm). Importantly, specialized reductive reaction Cu(II) enables remarkable selectivity toward analysis. Owing to synergistic large chemical sensitization effects from Cu-TCA, resulting Cu-TCA/TiO2 NCs show performance; i.e., ((Rgas - Rair)/Rair) reaches 124% 50 ppm 140 ppb RT. In addition, time decreases 25.6% if system subjected irradiation. as-formed membrane also demonstrated be practically effective flexible wearable devices quantitative This study facilitates use MOFs achieve synergistically enhanced sensitivity develop high-performance

Enzymatic biocatalysis is a sustainable technology. Enzymes are versatile and highly efficient biocatalysts, have been widely employed due to their biodegradable nature. However, because the three-dimensional structure of these enzymes predominantly maintained by weaker non-covalent interactions, external conditions, such as temperature pH variations, well presence chemical compounds, can modify or even neutralize biological activity. The enablement this category processes result several advances in areas molecular biology biotechnology achieved over past two decades. In scenario, metal–organic frameworks (MOFs) highlighted supports for enzyme immobilization. They be used ‘house’ specific enzyme, providing it with protection from environmental influences. This review discusses MOFs structures; emphasizes synthesis strategies, properties, applications; explores existing methods using immobilization various enzymes; lists possible modifications combinations other compounds formulate ideal given application.

Abstract Selecting a suitable support material for enzyme immobilization with excellent biocatalytic activity and stability is critical aspect in the development of functional biosystems. The highly stable metal‐free properties covalent‐organic frameworks (COFs) make them ideal supports immobilization. Herein, we constructed three kinds COFs via biofriendly one‐pot synthetic strategy at room temperature aqueous solution. Among developed (COF‐LZU1, RT‐COF‐1 ACOF‐1), horseradish peroxidase (HRP)‐incorporated COF‐LZU1 found to retain highest activity. Structural analysis reveals that weakest interaction between hydrated COF‐LZU1, an easiest accessibility by substrate, as well optimal conformation together promote bioactivity HRP‐COF‐LZU1. Furthermore, revealed be versatile nanoplatform encapsulating multiple enzymes. also offers superior protection immobilized enzymes under harsh conditions during recycling. comprehensive understanding interfacial interactions COF host guest, substrate diffusion, alteration within matrices represents opportunity design biocatalysts opens broad range applications these nanosystems.
