Ultrasound-aided synthesis of gold-loaded boron-doped graphene quantum dots interface towards simultaneous electrochemical determination of guanine and adenine biomolecules. ULTRASONICS SONOCHEMISTRY 2022; 83:105921. [PMID: 35066331 PMCID: PMC8783145 DOI: 10.1016/j.ultsonch.2022.105921] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Revised: 01/10/2022] [Accepted: 01/14/2022] [Indexed: 06/14/2023]
Abstract
To acquire substantial electrochemical signals of guanine-GUA and adenine-ADE present in deoxyribonucleic acid-DNA, it is critical to investigate innovative electrode materials and their interfaces. In this study, gold-loaded boron-doped graphene quantum dots (Au@B-GQDs) interface was prepared via ultrasound-aided reduction method for monitoring GUA and ADE electrochemically. Transmission electron microscopy-TEM, Ultraviolet-Visible spectroscopy-UV-Vis, Raman spectroscopy, X-ray photoelectron spectroscopy-XPS, cyclic voltammetry-CV, and differential pulse voltammetry-DPV were used to examine the microstructure of the fabricated interfaceand demonstrate its electrochemical characteristics. The sensor was constructed by depositing the as-prepared Au@B-GQDs as a thin layer on a glassy carbon-GC electrode by the drop-casting method and carried out the electrochemical studies. The resulting sensor exhibited a good response with a wide linear range (GUA = 0.5-20 μM, ADE = 0.1-20 μM), a low detection limit-LOD (GUA = 1.71 μM, ADE = 1.84 μM), excellent sensitivity (GUA = 0.0820 µAµM-1, ADE = 0.1561 µAµM-1) and selectivity with common interferents results from biological matrixes. Furthermore, it seems to have prominentselectivity, reproducibility, repeatability, and long-lastingstability. The results demonstrate that the fabricated Au@B-GQDs/GC electrode is a simple and effective sensing platform for detecting GUA and ADE in neutral media at low potential as it exhibited prominent synergistic impact and outstanding electrocatalytic activity corresponding to individual AuNPs and B-GQDs modified electrodes.

Abstract
DNA methylation has been identified as one of the important causes of tumorigenesis, so it is important to develop some advanced methods for detecting and quantifying DNA methylation. In this study, a label-free and enzyme-free one-step rapid colorimetric detection of DNA methylation based on unmodified Au nanoparticles(Au NPs)has been proposed. This method can quickly, efficiently, economically and easily colorimetric detect methylated DNA only by the color change of unmodified Au NPs solution without the covalent modification of Au NPs in advance or complicated instruments for implementation with practical limitations or expensive biological enzymes or traditional organic dyes during the reaction. The strategy employed the difference in electrostatic attraction of single-stranded DNA and double-stranded DNA against salt-induced aggregation of Au NPs. The method has a DNA methylated detection limit of 8.47 nM and it is distinctly visible to detect methylated DNA with the naked eye as low as 20 nM. Furthermore, the strategy has an ability to detect methylated DNA in the presence of abundant unmethylated DNA with the detection limit of 0.13% and as low as 1% methylated DNA can be distinguished in heterogeneous samples with the naked eye. Also, the stratagem provides a convenient and rapid platform for methylated DNA detection of human serum samples in one step, which displays a huge potential for clinical diagnosis and treatment of oncological diseases.

Abstract
In the field of genetics, epigenetics is the study of changes in gene expression without any change in DNA sequences. Chemical base modification in DNA by DNA methyltransferase, and specifically methylation, has been well studied as the main mechanism of epigenetics. Therefore, the determination of DNA methylation of, for example, 5'-methylcytosine in the CpG sequence in mammals has attracted attention because it should prove valuable in a wide range of research fields including diagnosis, drug discovery, and therapy. Methylated DNA bases and DNA methyltransferase activity are analyzed using conventional methods; however, these methods are time-consuming and require complex multiple operations. Therefore, new methods and devices for DNA methylation analysis are now being actively developed. Furthermore, microfluidic technology has also been applied to DNA methylation analysis because the microfluidic platform offers the promising advantage of making it possible to perform thousands of DNA methylation reactions in small reaction volumes, resulting in a high-throughput analysis with high sensitivity. This review discusses epigenetics and the microfluidic platforms developed for DNA methylation analysis.

Abstract
A simple, novel colorimetric nanosensor for DNA methylation based on the strength of hydrophobic interaction between DNA and gold nanoparticles was proposed. The nanosensing of oligonucleotides with four nitrogen bases was first demonstrated by dividing the bases into two groups (A/T and C/G) using the representative colors that correspond to Watson-Crick base pairing. By treatment of the genomic DNA with sodium bisulfite followed by PCR amplification, the methylation level of nasopharyngeal carcinoma cells treated with 5-aza-2'-deoxycytidine for up to 5 days could be discriminated by naked eye observation. Furthermore, 12 cancer cell lines that demonstrate heterogeneity with respect to DNA methylation could also be distinguished using the nanosensor, even for amplicons as long as 342 bp. These results demonstrate that the proposed colorimetric nanosensor could potentially be useful in epigenetic studies.

Abstract
Cadmium sulfide (CdS) was combined with chitosan (Chi) and gelatin (Gel) to prepare a CdS-Chi/Gel modified electrode. Chi exhibits a large positive charge density and was to provide a uniform of CdS surface. Gel exhibits high mechanical strength and low toxicity toward mammalian cells, and is non-antigenic biopolymer. CdS-Chi exhibits a lower contact angle than that of bare CdS, indicating that the hydrophilicity of the sample surface had increased. Electrochemical impedance spectroscopy (EIS) was used to determine diffusion coefficients and to characterize the electron transfer kinetics during the redox reactions. The surface morphologies of CdS-Chi and Gel were characterized using scanning electron microscopy (SEM) and atomic force microscopy (AFM). Differential pulse voltammetry (DPV) was used to detect the analytes. DPV not only increased the linear range of the electrocatalytic current, but also lowered the overpotential for oxidation interference in the measurements. The CdS electrode exhibited a enhanced electrocatalytic activity toward the analytes evaluated in this study. The presence of Gel enhanced the loading and stability of the electrode. The fabricated electrode was successfully used for the simultaneous electrochemical oxidation of guanine (G) and adenine (A).
