Biosens Bioelectron 2023; 242:115742. [PMID: 37832349 DOI: 10.1016/j.bios.2023.115742] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 09/18/2023] [Accepted: 10/04/2023] [Indexed: 10/15/2023]
Abstract
An electrochemical lateral flow immunoassay (eLFIA) strip with high reproducibility was developed to rapidly and accurately detect Streptococcus suis serotype 2. This proposed strip was fabricated by integrating ratiometric electrochemical detection and LFIA (R-eLFIA). The R-eLFIA exhibited excellent reproducibility, which was improved by 3.8 times compared to a single electrode. A dual-working screen-printed graphene electrode (SPGE) was designed by tuning the working electrode with electroactive species in the biosensing system. Ferrocene carboxylic acid (Fc) was used as a signal probe, and sunset yellow (SY) at one working electrode was used as an internal reference signal to provide a built-in correction for reducing the effects of inherent background current. S. suis serotype 2-specific antibodies were immobilized on a nitrocellulose membrane of LFIA, which is located on the position of Fc-SPGE. In the presence of the analyte, an immunocomplex formed on the region of Fc-SPGE, causing a decrease in Fc current while SY current remained constant. The current ratio's decrease was proportional to S. suis serotype 2's concentration. Under optimization, this biosensor showed good linearity in the range of 102-1010 CFU/mL with a limit of detection of 10 CFU/mL and achieved a rapid detection time (15 min). Moreover, the R-eLFIA biosensor exhibited excellent reproducibility and high selectivity and was applied in human serum samples. Thus, this study successfully matched the advantages of the ratiometric strategy and LFIA and has great potential to be used as an effective tool for rapidly detecting S. suis serotype 2 in clinical samples.

Abstract
Here we report on the design and synthesis of cationic water-soluble thiophene copolymers as reporters for colorimetric detection of microRNA (miRNA) in human plasma. Poly(3-alkoxythiophene) (PT) polyelectrolytes with controlled ratios of pendant groups such as triethylamine/1-methyl imidazole were synthesized for optimizing interaction with target miRNA sequence (Tseq). Incorporation of specific peptide nucleic acid (PNA) sequences with the cationic polythiophenes yielded distinguishable responses upon formation of fluorescent PT-PNA-Tseq triplex and weakly fluorescent PT-Tseq duplex, thereby enabling selective detection of target miRNA. Unlike homopolymers of PT (hPT), experimental results indicate the possibility of utilizing copolymers of PT (cPT) with appropriate ratios of pendant groups for miRNA assay in complex matrices such as plasma. As an illustration, colorimetric responses were obtained for lung cancer associated miRNA sequence (mir21) in human plasma, with a detection limit of 10 nM, illustrating the feasibility of proposed methodology for clinical applications without involving sophisticated instrumentation. The described methodology therefore possesses high potential for low-cost nucleic acid assays in resource-limited settings.

Abstract
A novel approach for miRNA assay using a cationic polythiophene derivative, poly[3-(3'-N,N,N-triethylamino-1'-propyloxy)-4-methyl-2,5-thiophene hydrobromide] (PT), immobilized on a quartz resonator is proposed. The cationic PT enables capturing of all RNA sequences in the sample matrix via electrostatic interactions, resulting in the formation of PT-RNA duplex structures on quartz resonators. Biotinylated peptide nucleic acid (b-PNA) sequences are subsequently utilized for the RNA assay, upon monitoring the PT-RNA-b-PNA triplex formation. Signal amplification is achieved by anchoring avidin coated nanoparticles to b-PNA in order to yield responses at clinically relevant concentration regimes. Unlike conventional nucleic acid assay methodologies that usually quantify a specific sequence of RNA, the proposed approach enables the assay of any RNA sequence in the sample matrix upon hybridization with a PNA sequence complementary to the RNA of interest. As an illustration, successful detection of mir21, (a miRNA sequence associated with lung cancer) is demonstrated with a limit of detection of 400 pM. Furthermore, precise quantification of mir21 in plasma samples is demonstrated without requiring PCR and sophisticated instrumentation.

Abstract
Conducting polymers (CPs) are a group of polymeric materials that have attracted considerable attention because of their unique electronic, chemical, and biochemical properties. This is reflected in their use in a wide range of potential applications, including light-emitting diodes, anti-static coating, electrochromic materials, solar cells, chemical sensors, biosensors, and drug-release systems. Electrochemical DNA sensors based on CPs can be used in numerous areas related to human health. This review summarizes the recent progress made in the development and use of CP-based electrochemical DNA hybridization sensors. We discuss the distinct properties of CPs with respect to their use in the immobilization of probe DNA on electrode surfaces, and we describe the immobilization techniques used for developing DNA hybridization sensors together with the various transduction methods employed. In the concluding part of this review, we present some of the challenges faced in the use of CP-based DNA hybridization sensors, as well as a future perspective.

Abstract
Microstructured optical fibers containing microchannels and Bragg grating inscribed were internally functionalized with a peptide nucleic acid (PNA) probe specific for a gene tract of the genetically modified Roundup Ready soy. These fibers were used as an optofluidic device for the detection of DNA by measuring the shift in the wavelength of the reflected IR light. Enhancement of optical read-out was obtained using streptavidin coated gold-nanoparticles interacting with the genomic DNA captured in the fiber channels (0%, 0.1%, 1% and 10% RR-Soy), enabling to achieve statistically significant, label-free, and amplification-free detection of target DNA in low concentrations, low percentages, and very low sample volumes. Computer simulations of the fiber optics based on the finite element method (FEM) were consistent with the formation of a layer of organic material with an average thickness of 39 nm for the highest percentage (10% RR soy) analysed.

Abstract
This article reviews recent progress in the development of ferrocene (Fc)-modified thin films and nanoparticles in relation to their biosensor applications. Redox-active materials in enzyme biosensors commonly use Fc derivatives, which mediate electron transfer between the electrode and enzyme active site. Either voltammetric or amperometric signals originating from redox reactions of Fc are detected or modulated by the binding of analytes on the electrode. Fc-modified thin films have been prepared by a variety of protocols, including insitu polymerization, layer-by-layer (LbL) deposition, host-guest complexation and molecular recognitions. Insitu polymerization provides a facile way to form Fc thin films, because the Fc polymers are directly deposited onto the electrode surface. LbL deposition, which can modulate the film thickness and Fc content, is suitable for preparing well-organized thin films. Other techniques, such as host-guest complexation and protein-based molecular recognition, are useful for preparing Fc thin films. Fc-modified Au nanoparticles have been widely used as redox-active materials to fabricate electrochemical biosensors. Fc derivatives are often attached to Au nanoparticles through a thiol-Au linkage. Nanoparticles consisting of inorganic porous materials, such as zeolites and iron oxide, and nanoparticle-based composite materials have also been used to prepare Fc-modified nanoparticles. To construct biosensors, Fc-modified nanoparticles are immobilized on the electrode surface together with enzymes.

Abstract
Water-insoluble statistical copolymer was synthesized by copolymerization of methyl methacrylate (MMA) with 2-(dimethylamino)ethyl methacrylate (DMA) via group transfer polymerization (GTP). The DMA residues of the precursor P(MMA-co-DMA) statistical copolymer were then quaternized by reacting with methyl iodide under mild conditions to get well-defined P(MMA-co-QDMA) cationic copolymer. Then, P(MMA-co-QDMA) copolymer was successfully used for surface modification of pencil graphite electrode (PGE) to develop a disposable DNA sensor. This P(MMA-co-QDMA) copolymer modified electrode (q-PGE) was examined for electrochemical monitoring of DNA by using differential pulse voltammetry (DPV) in contrast to unmodified one. The effect of both DNA concentration and sonication time was also examined based on the response of q-PGE. The detection limit was calculated to be 8.06 μg/mL at q-PGE. Electrochemical impedance spectroscopy (EIS) was used for the characterization of the surface modification of q-PGE and consequently, the results were found to be in good agreement with the voltammetric measurements.

Abstract
A water-soluble chitosan-coordinated cadmium polymer was synthesized, and its recognition of single-stranded and double-stranded DNA was investigated. The electrochemical analysis in the homogeneous solutions revealed that the chitosan-coordinated cadmium polymer association with a single stranded DNA was 48 times greater than with double-stranded DNA due to the different interaction with the two kinds of DNA. The surface-based electrochemically absorbed chitosan-coordinated cadmium polymer molecules were easily removed from the double-stranded DNA-modified electrode via rinsing but could not be removed from a single-stranded DNA-modified electrode. Based on this fact, the polymer was utilized as a redox indicator for DNA hybridization detection, as the polymer was able to recognize complementary, noncomplementary, and base-mismatched sequences with a low background interference. The target DNA sequence was quantified from 5.0 × 10-9 to 5.0 × 10-7 M with a detection limit of 4.2 × 10-9 M. The polymerase chain reaction amplification of DNA from the real sample of a kind of transgenically modified soybeans was also detected satisfactorily.

Abstract
A homothymine PNA decamer bearing four lysine residues has been synthesized as a probe for the development of amperometric sensors. On one hand, the four amino groups introduced make this derivative nine times more soluble than the corresponding homothymine PNA decamer and, on the other hand, allow the stable anchoring of this molecule on Au nanostructured surface through the terminal -NH2 moieties. In particular, XPS and electrochemical investigations performed with hexylamine, as a model molecule, indicate that the stable deposition of primary amine derivatives on such a nanostructured surface is possible and involves the free electron doublet on the nitrogen atom. This finding indicates that this PNA derivative is suitable to act as the probe molecule for the development of amperometric sensors.
Thanks to the molecular probe chosen and to the use of a nanostructured surface as the substrate for the sensor assembly, the device proposed makes possible the selective recognition of the target oligonucleotide sequence with very high sensitivity.

Abstract
We report a new electrochemical amplification strategy for an ultrasensitive electrochemical detection of DNA sequences using aggregates composed of a water-soluble, ferrocene-functionalized polythiophene. A two-step hybridization is performed at one addressing surface with PNA capture probes whereas the electrochemical detection is done on an electrode nearby. Specific and quantitative detection of DNA targets with a detection limit of 4 × 10(-16) M (about 4 zeptomoles or about 2500 copies of oligonucleotides) was achieved.

Abstract
In this study, ZnO nanoparticles (ZNP) of approximately 30 nm in size were synthesized by the hydrothermal method and characterized by X-ray diffraction (XRD), Braun-Emmet-Teller (BET) N2 adsorption analysis and transmission electron microscopy (TEM). ZnO nanoparticles enriched with poly(vinylferrocenium) (PVF+) modified single-use graphite electrodes were then developed for the electrochemical monitoring of nucleic acid hybridization related to the Hepatitis B Virus (HBV). Firstly, the surfaces of polymer modified and polymer-ZnO nanoparticle modified single-use pencil graphite electrodes (PGEs) were characterized using scanning electron microscopy (SEM). The electrochemical behavior of these electrodes was also investigated using differential pulse voltammetry (DPV) and electrochemical impedance spectroscopy (EIS). Subsequently, the polymer-ZnO nanoparticle modified PGEs were evaluated for the electrochemical detection of DNA based on the changes at the guanine oxidation signals. Various modifications in DNA oligonucleotides and probe concentrations were examined in order to optimize the electrochemical signals that were generated by means of nucleic acid hybridization. After the optimization studies, the sequence-selective DNA hybridization was investigated in the case of a complementary amino linked probe (target), or noncomplementary (NC) sequences, or target and mismatch (MM) mixture in the ratio of (1:1).

Abstract
An electrochemical aptasensor based on Klenow fragment (KF) polymerase reaction that combines the aggregation of ferrocene-functionalized oligonucleotide has been developed successfully for cocaine detection. In the presence of cocaine, the recognition probe changed its hairpin conformation into the tripartite complex. The aptamer-cocaine complex gave a 3'-single-stranded tail sequence complementary to the surface-tethered capture probe. In KF polymerase reaction, the recognition probe served as a template for the extension of a capture probe. It requires a sample volume of 2 μL and is complete within 1 h. The ferrocene-appended oligonucleotide incorporated into the newly synthesized complementary probe leads to an electrochemical response. This sensitive detection of cocaine is due to a very low background signal and large signal enhancement up to 9-fold upon addition of analyte. It permits detection of as low as 200 μM cocaine. The simple and isothermal procedure does not require thermal cycling or special laboratory conditions, which makes it adaptable to low-cost and robust biosensing.

Abstract
Thiolated pyrrolidinyl peptide nucleic acids (HS-PNAs) bearing d-prolyl-2-aminocyclopentanecarboxylic acid (ACPC) backbones with different lengths and types of thiol modifiers were synthesized and then characterized by MALDI-TOF mass spectrometry. These HS-PNAs were immobilized on gold-coated glass by self-assembled monolayer (SAM) formation via S atom linkage for the detection of DNA hybridization using surface plasmon resonance (SPR). The amount and the stability of the immobilized HS-PNAs, as well as the effects of spacer and blocking thiol on DNA hybridization efficiency, were determined. SPR results indicated that the hybridization efficiency was enhanced when the distance between the PNA portion and the thiol terminal was increased and/or when blocking thiol was used following the HS-PNA immobilization. The immobilized HS-PNA could discriminate between fully complementary DNA from one or two base mismatched DNA with a relatively high degree of mismatch discrimination (>45%) in PBS buffer at 25 degrees C. The lowest DNA concentration at which reliable discrimination between fully complementary and single mismatched DNA could still occur was at about 0.2 microM, which is equivalent to 10 pmol of DNA. This research demonstrates that using these novel thiolated PNAs in combination with the SPR technique offers a direct, rapid and non-label based method that could potentially be applied for the analysis of genomic or PCR-amplified DNA in the future.

Abstract
The amplified electrochemical sensing of DNA was accomplished by electrodeposited PEDOT on the electrode surface and incorporation of Nile blue (NB) as redox active intercalator into DNA. Herein, above modified electrode called as PEDOT/DNA/NB composite electrode. PEDOT/DNA/NB composite electrode exhibited well defined redox peak at -0.35 V (Ag/AgCl) corresponding to NB. The composite electrode surface coverage (Gamma) and DeltaEp were compared with PEDOT/NB and DNA/NB modified electrode. Atomic Force microscopy (AFM), and cyclic voltammetry (CV) were used to characterize the PEDOT/DNA/NB composite electrode. The composite electrode was exhibited as surface confined redox process in neutral pH. The composite electrode was found to be pH dependent. The composite electrode exhibited catalytic property towards reduction of hydrogen peroxide (H(2)O(2)). The composite electrode was utilized to amperometric study and its response towards H(2)O(2) detection was less than 6 s and the detection limit was 0.1 microM. Moreover, we tested PEDOT/DNA/NB composite electrode to electrocatalytic reduction of cytochrome c (Cyt c).
