“…Luminescent metal–organic framework (LMOF) is a light-emitting crystalline porous material self-assembled by organic connectors and metal nodes or clusters . It is widely used, such as in bioimaging, drug release, food inspection and so on, − due to its abundant luminescent sites, high selectivity, supersensitivity, and easy modification of the channels. , Zinc-based metal–organic frameworks (Zn-MOFs) are one of the most important components in the LMOF family. Zn(II) shows excellent luminescence properties due to its d 10 configuration .…”

Uncontrolled industrialization not only caused irreparable damage to the surrounding ecological environments, especially water resources, but also seriously threatened human health. How to sensitively detect toxic pollutants in the hydrological system is a prerequisite for protecting human life. The luminescent metal–organic frameworks (LMOFs) have excellent applications in this field. Herein, four Zn-MOFs, namely [Zn3(dpcp)2(1,4′-bmib)2]n (1), {[Zn4(dpcp)2(4,4′-bibp)2(μ2-O)4]·3H2O}n (2), [Zn(2-ata)(bidpe)]n (3), and [Zn(bbibp)(HCOO)2]n (4) (dpcp = 3-(3,5-dicarboxylphenoxy)-5-carboxylpyridine, 2-ata = 2-aminoterephthalic acid, 1,4′-bmib = 1,4-bis(2-methylimidazol-1-yl) butane, 4,4′-bibp = 4,4′-bis(imidazolyl) biphenyl, bbibp = 4,4′-bis(benzoimidazo-1-ly) biphenyl, bidpe = 4,4′-bis(lmidazolyl)diphenyl ether), were synthesized by solvothermal method and characterized by single crystal X-ray diffraction. For tetracycline, o-nitro phenol, Cr2O7 2– and Fe3+, 1–4 have different degrees of fluorescence quenching effect and exhibit good sensitivity and high-selective detection of the above analytes in the presence of multiple interference species (such as antibiotics, amino acids, metal ions and inorganic ions). Additionally, the heat map and principal component analysis plot visually represent the selective detection effect of Fe3+, Cr2O7 2– and tetracycline by 1–4. Besides, 3 can detect PO4 3– and Al3+ independently with high selectivity from homogeneous pollutants through the fluorescence enhancement phenomenon. This work offers insight into exploring the potential applications of zinc-based MOFs in the chemical sensing field.

“…Mercury, present in a variety of different forms (including metallic, inorganic, and organic), is well known as a widespread bio-accumulative pollutant, and ionic mercury (Hg 2+ ) is a neurotoxin that can lead to serious damage to nervous tissues and organs, and also causes toxicity in vivo . ,− Consequently, it is of great importance to develop highly sensitive and selective biosensors for Hg 2+ detection in environmental monitoring, food safety, and clinical therapy. So far, various methods for detecting Hg 2+ have been reported, such as fluorescence sensors, − colorimetric sensors, − surface-enhanced Raman scattering, − and electrochemical sensors. − In 2013, Tian et al developed a biomimetic Hg 2+ -gated nanochannel by functionalizing thymine-rich ssDNA onto the inner surface of a single conical PI nanochannel, and the ssDNA bonded with Hg + to form strong and stable T-Hg + -T complexes . The principle of this device was that the thymine-rich ssDNA would undergo conformational changes in the presence and absence of Hg 2+ , and the sensor showed high sensitivity with a detection limit of 8 nM and high selectivity toward Hg 2+ .…”

Bio-inspired Track-Etched Polymeric Nanochannels: Steady-State Biosensors for Detection of Analytes

2021

Bio-inspired polymeric nanochannel (also referred as nanopore)-based biosensors have attracted considerable attention on account of their controllable channel size and shape, multi-functional surface chemistry, unique ionic transport properties, and good robustness for applications. There are already very informative reviews on the latest developments in solid-state artificial nanochannel-based biosensors, however, which concentrated on the resistive-pulse sensing-based sensors for practical applications. The steady-state sensing-based nanochannel biosensors, in principle, have significant advantages over their counterparts in term of high sensitivity, fast response, target analytes with no size limit, and extensive suitable range. Furthermore, among the diverse materials, nanochannels based on polymeric materials perform outstandingly, due to flexible fabrication and wide application. This compressive Review summarizes the recent advances in bio-inspired polymeric nanochannels as sensing platforms for detection of important analytes in living organisms, to meet the high demand for high-performance biosensors for analysis of target analytes, and the potential for development of smart sensing devices. In the future, research efforts can be focused on transport mechanisms in the field of steady-state or resistive-pulse nanochannel-based sensors and on developing precisely size-controlled, robust, miniature and reusable, multi-functional, and high-throughput biosensors for practical applications. Future efforts should aim at a deeper understanding of the principles at the molecular level and incorporating these diverse pore architectures into homogeneous and defect-free multi-channel membrane systems. With the rapid advancement of nanoscience and biotechnology, we believe that many more achievements in nanochannel-based biosensors could be achieved in the near future, serving people in a better way.

“…However, due to the narrow range of spectral lines and standard working curves, as well as the difficulty in analyzing complex samples, it is inconvenient for the actual detection. [7,8] ICPAES analysis is fast and accurate, but the equipment is expensive and the sample pretreatment is tedious. [9][10][11] By contrast, fluorescence analysis can easily realize complex sample detection, [12] and it also is more cheaper and convenient to use.…”

A novel fluorescent Schiff base polymer (PTDA-DATA-SBP) is synthesized by amine aldehyde condensation reaction between 1,10-phenanthroline-2,9-dicarboxaldehyde (PTDA) and 2,5-diaminoterephthalicacid (DATA) as a selective fluorescent probe for Cu 2 + detection. The as-prepared PTDA-DATA-SBP displayed irregular nanospheres with a diameter of about 5 μm. Under the excitation of 338 nm, the PTDA-DATA-SBP had a characteristic emission peak at 565 nm. The PTDA groups in PTDA-DATA-SBP could coordinate with Cu 2 + under help of carboxyl groups of DATA. Owing to the photoinduced electron transfer mechanism, the fluorescence of PTDA-DATA-SBP was weak-ened after the addition of Cu 2 + in the presence of common ions. Hence, the PTDA-DATA-SBP was exploited as a fluorescent nanosensor for sensing Cu 2 + . The PTDA-DATA-SBP showed high selectivity and fast response towards Cu 2 + even in presence of other relevant metal ions. The PTDA-DATA-SBP fluorescent sensor has a good linear range of 3.45 nM-8.00 μM, and the limit of detection was as low as 1.15 nM. The proposed PTDA-DATA-SBP sensor could also detect Cu 2 + in actual samples. The work not only provided a good fluorescent probe for Cu 2 + detection but also provided a feasible strategy to construct highly selective fluorescent probes.
