Abstract :

DNA材料具有的特异性、可编程性和生物相容性,使得其在生物检测和药物递送方面具有很大的应用优势。为了进一步拓展DNA材料的应用和合成方法,本文报道了利用DNA与金属离子之间的配合作用,简单高效地制备具有肿瘤标志物micro RNA-21(mi R-21)响应性的Zn~(2+)/DNA自组装纳米粒子(ZDNPs)。通过粒子中DNA发卡结构与mi R-21的特异性互补,激活荧光信号并释放Zn~(2+),导致细胞内产生大量活性氧,从而用于肿瘤的荧光成像和氧化应激治疗。合成的ZDNPs为形状均匀的球形粒子,能有效对Zn~(2+)进行装载。通过ZDNPs对mi R-21的响应性实验,验证了ZDNPs与miR-21浓度之间具有良好的线性响应荧光信号,线性响应范围在5~160 nmol/L,检测限为5 nmol/L,且具备特异性。此外,本文对ZDNPs在细胞内的作用效果也进行了研究,结果表明其能在肿瘤细胞内进行响应性的荧光成像,并能通过氧化应激途径介导肿瘤细胞凋亡。在活体的荧光成像和肿瘤治疗中,ZDNPs在肿瘤病灶部位体现出特异性和持续性的示踪能力,并且对肿瘤产生了明显的生长抑制效果。

Strategy and mechanism for strong and stable electrochemiluminescence of graphitic carbon nitride SCIE
期刊论文 | 2023 , 444 | ELECTROCHIMICA ACTA

Abstract&Keyword Cite

Abstract :

Electrochemiluminescence (ECL) of graphitic carbon nitride nanosheets (CNNSs) is showing extensive interest to researchers. However, the poor ECL stability of CNNSs has always been an urgent problem, which severely limits its application. Herein, a systemic investigation is carried out for the exact mechanism affecting the ECL stability of CNNSs. It is found experimentally that dissolved oxygen in the solution is selectively reduced into H2O2 through a two-electron pathway on the surface of CNNSs. The enriched electrogenerated H2O2 on the electrode surface leads to the progressive inhibition of ECL of CNNSs due to its competition with negatively charged CNNSs (CNNSs center dot-) for sulfate radical ions (SO4 center dot-). On the basis, the pathway of eliminating O2 by N2, composing CNNSs with other nanomaterials to realize the four-electron reduction, or improving the concentration of K2S2O8 is proved to be effective means for improving ECL stability successfully. Proofing the concept of CNNSs with high ECL stability, an ECL sensor is developed for the detection of H2O2. This work not only exploits the intrinsic mechanism of poor ECL stability of CNNSs, but also provides efficient methods to improve the ECL stability. Thus, we believe it has promising attraction in the research of CNNSs-based assays.

Efficient capture and highly sensitive analysis of okadaic acid by three-dimensional covalent organic frameworks with hydroxyl surface engineering SCIE

Abstract&Keyword Cite

Abstract :

A novel three-dimensional covalent organic framework (3D-COF) with content-tunable and active hydroxyl groups (OH) on the pore walls was developed and adopted for the high-performance capture of okadaic acid (OA) marine toxins. Using pore-surface engineering, the integration of linear building blocks (4,4'-diamino-3,3'- biphenyldiol, BD(OH)2 and benzidine, BD) with the 3D structural building block backbone (4,4',4',4'''-methane-tetrayltetrabenzaldehyde, TFPM) was achieved. By adjusting the ratio of BD(OH)2, functional multicomponent-COFs [OH](x)-BD-TFPM COFs (X = 25%) were synthesized, which offered ideal access to convert a conventional COF into a functional platform with multiple-mode interactions of hydrophobic and hydrophilic groups for OA capture. [OH](x)-BD-TFPM was characterized using SEM, XRD, FT-IR, and BET. The adsorption features and analytical performance of OA were screened and evaluated. Optimization of dispersive solid-phase extraction using [OH]25-BD-TFPM was accomplished, and the method was verified for sensitive quantitative detection of OA in clam and mussel samples. Coupled with LC-MS/MS, the resultant [OH]25-BD-TFPM COF demonstrated the ability to analyze OA, and the limit of detection for OA in shellfish was determined to be 0.005 mu g/kg. A significant improvement in trace OA detection was observed compared to previously reported SPE materials without adjustable hydrophilic interactions. The recoveries of OA in the fortified clam and mussel samples were in the ranges of 93.9-105.1% and 96.7-110.2%, respectively. This study highlights that OH-group surface engineering in channel walls is a facile and powerful strategy for developing functional 3D-COFs with multiple interactions for high-performance target capture.

Abstract :

MC-LR possessing strong hepatotoxicity, potential carcinogenicity, and biological toxicity could have an intensive influence on human health and the aquatic ecological environment and need to be monitored critically. For the specific and highly sensitive analysis performance, agold-magnetic composite nanoparticlemodified by aptamer-cDNAfluorescent hybridization probe (Fe3O4@ MIL-101 -NH2 @Au@aptamer) was prepared and applied for sensing detection of MC-LR in water with laser-induced fluorescence (LIF). This work studied the feasibility, optimization of analysis conditions, specificity, stability of the method, and sample analysis application. As a result, a high Brunauer-Emmett-Teller (BET) specific surface area of 114. 02 m(2) center dot g(-1) was achieved in Fe3O4@ MIL-101-NH2@ AuNPs, which resulted in a high modification rate of up to 98. 8%0 achieved for aptamercDNA fluorescenthybridization probe. With the excitation wavelength of 497 nm, the aptamer-cDNA fluorescent probe has a strong fluorescence response with the emission wavelength of 512 nm to the trace MC-LR. Under the optimal conditions (pH 7. 5, NaC1 concentration 500 mmol center dot L-1 nanogold size 20 nm, analytical time 30 min), a good linear relationship between MCLR concentration and fluorescence intensity was achieved in a wide linear range (0. 020 similar to 3. 000 mu g center dot L-1) with the limit of detection (LOD) as low as 0. 006 mu g center dot L-1, which was 1. 6 similar to 22. 3 folds better than that of the most fluorescence methods reported previously. The relative standard deviation (RSD) of intra-day, intra-day, and inter-batch was gained in 1. 7%similar to 8. 8%, and the relative error (RE) of -4. 3%similar to 4. 1%0. High specific selectivity and low cross-reactivity for MC-LR (1. 0 mu g center dot L-1) were also achieved using theas-prepared fluorescent probe, even if the concentration of interfering toxins (MC-RR, MCYR, OA) was 100 folds higher than that of MC-LR. The fluorescence responses of MC-LR in these mixtures werewell consistent with that of MC-LR in the standard solution. Applied to the analysis of samples from the Minjiang River, Lake Water, and the inland river, the identification of MC-LR in water samples was satisfactory. The recovery yields of MC-LR for three concentrations (0. 050, 0. 100 and 1. 000 mu g center dot L-1) rangedin (90. 1%+/- 0 6. 4%) (104. 2%+/- 7. 0%) (n=3). The results were consistent with those obtained by the LC-MS method [(91. 3%+/- 0 7. 0%) (104. 4%+/- 2. 0%), n=3]. It might light a new technique for the specific and rapid monitoring technology for tracing MC-LR in the environmental water.

Abstract :

Herein, a vinylene-linked covalent organic framework (TMT-BPDA-COF) was prepared via the Aldol condensation of 2,4,6-trimethyl-1,3,5-triazine (TMT) and 4,4'-biphenyl dimethyl formaldehyde (BPDA). TMT-BPDACOF displayed high crystallinity and thermal stability, and robust chemical stability in strong acid, strong base and common organic solvents. TMT-BPDA-COF nanosheets emitted strong yellow fluorescence with the quantum yield of 14.9% and showed fast reversible response toward pH with a wide range (pH 0.0 - 14.0) based on the intramolecular charge transfer effect. Furthermore, portable fluorescent sensors were prepared by incorporated TMT-BPDA-COF nanosheets into agarose gel and cellulose acetate butyrate (CAB), respectively. TMT-BPDA-COF gel showed a wide pH response range over pH 0.0 - 14.0 with a linear range of pH 4.0 - 14.0. TMT-BPDA-COF CAB film exhibited high sensitivity for sensing of NH3 gas with a limit of detection of 1.6 ppb. TMT-BPDA-COF agarose gel and CAB film also exhibited good reversibility and reproducibility in response to pH and NH3 gas, respectively. We expect TMT-BPDA-COF-based sensors, which feature fast response, high sensitivity, wide response range, good reproducibility and reversibility, can apply to detect pH and NH3 gas in the field of environment and industry.
