Self-calibrating sensor with logic gate operation for anthrax biomarker based on nanoscaled bimetallic lanthanoid MOF

A multi-responsive luminescent sensor based on a stable Eu(iii) metal–organic framework for sensing Fe3+, MnO4−, and Cr2O72−in aqueous solutions

“…[6][7][8][9][10] These features establish Eu(III)-based MOFs as excellent luminescence sensors for nitro-explosives, small molecules, anions, and cations. [11][12][13][14][15][16][17][18] The acceleration of industrialization and urban development has led to the increase of environmental problems. [19][20][21][22] In life science and environmental science, it is important to quickly detect ions with low detection limit, high sensitivity and selectivity.…”

“…27 Among them, Fe 3+ ion plays an indispensable role in industrial and biochemical systems. 28 Excess Fe 3+ ions not only are considered as industrial pollution, 11 but also can cause physiological diseases. 29,30 The anion Cr 2 O 7 2− , which is also a typical pollution ion in wastewater, produced by chromium plating, printing and dyeing and other industrial processes, which is listed as a priority pollutant by the US Environmental Protection Agency.…”

Recent Advances in Developing Lanthanide Metal–Organic Frameworks for Ratiometric Fluorescent Sensing

“…The traditional method of physically mixing two types of LnMOFs doped with different lanthanide ions, as illustrated in (i) of Figure 1B , is the most straightforward way to obtain dual emission ( Chen et al, 2019 ). Due to the similar chemical properties of lanthanide ions, LnMOF structures can also allow for the incorporation of different types and ratios of lanthanide ions into the same host materials and thus generate characteristic emissions of each lanthanide ion at the same time ((ii) of Figure 1B ) ( Xia et al, 2017 ; Su et al, 2018 ; Ji et al, 2018 ; Gao et al, 2018 ; Li et al, 2019a ; Othong et al, 2020 ; Zeng et al, 2020a ). Once incorporated into the MOF structure, lanthanide ions can generate emission covering the spectrum region from ultraviolet to near-infrared.…”

Au@Zr-based metal–organic framework composite as an immunosensing platform for determination of hepatitis B virus surface antigen

“…Over the past 10 years, the available literature on metal-organic frameworks (MOFs) has increased rapidly. MOFs are among the materials that have the highest porosities, and their pore size, shape, dimensionality, and chemical environment can be finely tuned [24,25]. However, only a few research reports have demonstrated the successful fabrication of the MOFs due to several inherent problems, such as arduous self-assembly, poor water resistance, and tedious fabrication strategies [26].…”
