“…When excited at 375 nm, both CoMOF-1 and CoMOF-2 exhibited strong emissions at about 450 nm, which can be mainly attributed to the π–π* electron transition of an organic ligand (Figure ). − Considering the main focus of this work is on the water-stable MOFs as luminescence sensors for detecting the 3-NT biomarker in serum, then the suspensions of CoMOFs and the standard water-stabilized MOF of UiO-66 were configured in 5 mM PBS buffer solutions to test the fluorescence response of various serum species (NaCl, KCl, CaCl 2 , Na 2 SO 4 , NH 4 Cl, Cre, Crea, UA, urea, His, Cys, Phe, Glut, Glue, and 3-NT) to the luminescent intensity of CoMOFs. In order to not make the sauce better than the fish, we only measured some important parameters of UIO-66 in the following tests.…”

Rapid detection of the 3-nitrotyrosine (3-NT) biomarker in serum is of great significance in clinical diagnosis and daily disease monitoring. In this work, two chemorobust 3D metal–organic frameworks (MOFs) of [Co(DBrTPA)(NMP)] n (CoMOF-1) and [Co5(DBrTPA)4(DMF)6(HCOO)2] n (CoMOF-2) were fabricated from a halogen-modified ligand of 2,5-dibromoterephthalic (H2DBrTPA) and cobalt(II) clusters under solvothermal conditions. The introduction of halogens can improve the stability of the overall framework in different media and pH environments, which also endow two CoMOFs with great potential as luminescent sensors with high sensitivity and selectivity, fast response, good anti-interference, as well as recyclable performance in detecting 3-NT in a PBS buffer solution through quenching effects, with the K sv values being 9.19 × 104 M–1 for CoMOF-1 and 1.05 × 105 M–1 for CoMOF-2 and the LODs as low as 23.6 ng·mL–1 for CoMOF-1 and 20.1 ng·mL–1 for CoMOF-2. Furthermore, the developed sensors were employed to quantify 3-NT in real serum samples, with satisfactory results. In addition, the possible sensing mechanisms of CoMOFs toward the 3-NT biomarker were also discussed from photoinduced electron transfer and spectral overlaps. This work demonstrated the excellent potential of MOF-based sensors for biomarker detection in serum and provided an outlook to design MOF-based sensors with the help of artificial intelligence and machine learning.

“…It was discovered that N-doping in ZnO increased the appearance of oxygen vacancies, which improved the generation of adsorbed oxygen species to accomplish enhanced gas-sensing performance. The enhanced ethanol-sensing performance may also be attributed to the greater specific surface area produced by the size reduction during the urea-assisted pyrolysis process . Precious NPs (Pd, Pt, and Au) have been included in ZIFs to enhance their use in composite materials to efficiently promote the reaction rates. − Different functional groups of ZIFs can separate and absorb gases that flow through their channels with high selectivity.…”

Chemiresistors have been widely employed in monitoring toxic fumes, gases, and environmental pollutants. Among a plethora of metal oxide semiconductors (MOX) used for preparing chemiresistors, zinc oxide is the topmost candidate. ZnO-based gas sensors are cost-effective, nontoxic, stable, and easily prepared by wet chemical facile approaches. ZnO nanostructures are the most promising candidates for leakage detection of toxic gases with reliable performance. In this regard, several investigations have been carried out to increase sensor response at room temperature (RT). Current advances in ZnO nanostructures-based thin films are the subject of this review paper. The review begins with a basic survey of ZnO thin films for gas sensors focusing on how the structure and properties of ZnO affect the gas response mechanisms, various factors and processing methods of ZnO nanostructures, and possible ways to enhance the gas response characteristics of ZnO-based sensors.
