Electrochemical Sensors Modified with Combinations of Sulfur Containing Phthalocyanines and Capped Gold Nanoparticles: A Study of the Influence of the Nature of the Interaction between Sensing Materials. NANOMATERIALS 2019; 9:nano9111506. [PMID: 31652754 PMCID: PMC6915348 DOI: 10.3390/nano9111506] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/13/2019] [Revised: 10/11/2019] [Accepted: 10/16/2019] [Indexed: 01/12/2023]
Abstract
Voltametric sensors formed by the combination of a sulfur-substituted zinc phthalocyanine (ZnPcRS) and gold nanoparticles capped with tetraoctylammonium bromide (AuNPtOcBr) have been developed. The influence of the nature of the interaction between both components in the response towards catechol has been evaluated. Electrodes modified with a mixture of nanoparticles and phthalocyanine (AuNPtOcBr/ZnPcRS) show an increase in the intensity of the peak associated with the reduction of catechol. Electrodes modified with a covalent adduct-both component are linked through a thioether bond-(AuNPtOcBr-S-ZnPcR), show an increase in the intensity of the oxidation peak. Voltammograms registered at increasing scan rates show that charge transfer coefficients are different in both types of electrodes confirming that the kinetics of the electrochemical reaction is influenced by the nature of the interaction between both electrocatalytic materials. The limits of detection attained are 0.9 × 10−6 mol∙L−1 for the electrode modified with the mixture AuNPtOcBr/ZnPcRS and 1.3 × 10−7 mol∙L−1 for the electrode modified with the covalent adduct AuNPtOcBr-S-ZnPcR. These results indicate that the establishment of covalent bonds between nanoparticles and phthalocyanines can be a good strategy to obtain sensors with enhanced performance, improving the charge transfer rate and the detection limits of voltammetric sensors.

Abstract
The applications of graphene field-effect transistors (FETs) for monitoring DNA hybridization have been widely accepted; however, for evaluating DNA methylation degree, an emerging requirement of epigenetic research, no work has been found due to the difficulties in detecting 5-methylcytosine (5mC) sites along the genomic sequence as well as counting their amount (NmC). Herein, to achieve this, a strategy for exploiting a liquid exfoliated graphene (LEG)-based FET (LEG-FET) as a sensing platform was proposed. First, LEG-FETs were prepared and activated by tetra-4-aminophenyl-porphyrin (TAPP) for anchoring single-strand DNAs (ssDNAs). Second, the 5mC sites in ssDNA were recognized by the specifically absorbed 5mC antibody (5mCab) and transduced to the changed currents (ΔIDS) by LEG-FET according to the integration of the methylation-immuno sensing principle and FET's working mechanism. Briefly, more 5mCab molecules could be captured by more 5mC sites, resulting in larger ΔIDS. The TAPP effects on LEG-FET were analyzed by SEM, Raman, AFM, and XPS characterizations as well as electronic measurements. The validity of this LEG-FET sensing platform for evaluating DNA methylation degree was proven step by step; this included the examinations of the synthesized ssDNAs with the known NmC and real ssDNA samples, whose methylation degrees were pre-determined by the gold-standard method, which is based on tedious bisulphite sequence operations and expensive mass spectrometry technology. Moreover, theoretical explanations were also provided for the sensing mechanism in the proposed DNA methylation analytical components. In conclusion, the positive and linear relations of IDS changing ratio vs. NmC as well as the detection limit of one 5mC site indicate that TAPP-modified LEG-FET can provide an alternative analytical tool to realize fast and economical DNA methylation evaluation.

Abstract
Fe(III)-complexes of amino-substituted tetraphenylporphyrins obtained from solutions in organic solvents: dichloromethane, ethanol, and dimethyl sulfoxide have been electropolymerized. The solvents’ effects on deposition and surface morphology of the obtained polyporphyrin film have been determined. It is only possible to obtain a polyporphyrin film from DMSO solutions through electrochemical activation of electropolymerization by a superoxide anion radical (O[Formula: see text]. The activation effect of the dissolved oxygen becomes evident in porphyrin interaction with the superoxide anion radical (O[Formula: see text] that is synthesized in DMSO thanks to the quasi-reversible redox process. The size of particles forming the film is lowest when the film is deposited from DMSO and highest when it is deposited from dichloromethane. Therefore, the ratio of polyporphyrin phase grain growth rate to the nucleation rate has the highest value when the film is deposited from dichloromethane. Such films have the most developed surfaces, while those deposited from ethanol are the smoothest. If the film is deposited on an ITO-electrode, the particles forming the surface are a little larger than in the case of deposition on Pt, which is explained by a slower nucleation on the ITO surface. FeClT([Formula: see text]-NH2Ph)P-based films obtained from ethanol and dichloromethane have negative photo-EMF values, which indicates that the [Formula: see text]-type films have semiconductor properties.

Abstract
Porphyrins are a kind of aromatic molecules possessing unique physic-chemical properties. In this manuscript, it was thus utilized to synthesize 5,10,15-tris(4-aminophenyl)-20-phenylporphyrin and cobalto(5,10,15-tris(4-aminophenyl)-20-phenylporphyrin). In addition, conducting cobalto(5,10,15-tris(4-aminophenyl)-20-phenylporphyrin) polymeric films were successfully prepared by electropolymerization approach on glassy carbon electrode in the presence of dimethyl formamide solution and 0.1 M tetra-n-butyl ammonium perchlorate at 100 mV/s scan rate. The synthesized polymeric films were evaluated as the active electrode materials to detect an antioxidant (Antipyrine) present in pharmaceuticals and the limit of detection is ~ 74 μM.
