An ultrasensitive electrochemical immunosensor based on meso-PdN NCs and Au NPs/N-CNTs for quantitative cTnI detection. Bioelectrochemistry 2024; 158:108680. [PMID: 38493575 DOI: 10.1016/j.bioelechem.2024.108680] [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: 01/30/2024] [Revised: 03/04/2024] [Accepted: 03/07/2024] [Indexed: 03/19/2024]
Abstract
Electrochemical immunosensors have gained considerable attention in detecting human disease markers due to their excellent specificity, high sensitivity, and facile operation. Herein, a rational-designed sandwich-type electrochemical immunosensor is constructed for the sensitive detection of cardiac troponin I (cTnI) using nitrogen-doped carbon nanotubes loaded with gold nanoparticles (Au NPs/N-CNTs) as substrate and highly active mesoporous palladium-nitrogen nanocubes (meso-PdN NCs) as secondary antibody markers. Benefitting from its large specific surface area (638.04 m2 g-1) and high nitrogen content, novel polydopamine (PDA)/ halloysite nanotubes (HNTs) hybrid derived one-dimensional (1D) N-CNTs can provide more binding sites for the in-situ growth of Au NPs to connect Ab1. Furthermore, as an ideal substrate material, Au NPs/N-CNTs exhibit finely tuned mesoporous structures and outstanding conductivity, which facilitate the mass and electron transfer during the electrocatalysis process. Besides, highly concave surfaces and crystalline mesopores of meso-PdN NCs expose more surfaces and crevices, providing abundant reactive sites for H2O2 reduction. Remarkably, the as-obtained immunosensor presented a wide linear range (from 10 fg mL-1 to 100 ng mL-1) and an excellent low detection limit (9.85 fg mL-1). This study may offer new insights into the precise fabrication of efficient electrochemical immunosensors for various clinical diagnosis applications.

Abstract
One of the current challenges in medicine is to achieve a rapid and unequivocal detection and quantification of extremely low levels of disease biomarkers in complex biological samples. Here, we present the development and analytical evaluation of a low-cost smartphone-based system designed for ultrasensitive detection of the prostate-specific antigen (PSA) using two detection alternatives: electrochemical or optical, by coupling the smartphone with a portable potentiostat or magnifying lenses. An antibody tagged with gold nanoparticles (AuNPs), and indium tin oxide coated polyethylene terephthalate platform (ITO-PET) have been used to develop a sandwich-type immunoassay. Then, a controlled silver electrodeposition on the AuNPs surface is carried out, enhancing their size greatly. Due to such strong nanoparticle-size amplification (from nm to μm), the final detection can be dual, by measuring current intensity or the number of silver-enlarged microstructures generated. The proposed strategies exhibited limit detections (LOD) of 102 and 37 fg/mL for electrochemical and optical detection respectively. The developed immunosensor reaches excellent selectivity and performance characteristics to quantify biomarkers at clinically relevant values without any pretreatment. These proposed procedures could be useful to check and verify possible recurrence after clinical treatment of tumors or even report levels of disease serum biomarkers in early stages.

Abstract
The presence of lead ions (Pb2+) in the environment not only leads to environmental contamination but also poses a significant risk to public health through their migration into food and drinking water. Therefore, the development of rapid and effective techniques for detection of trace amounts of Pb2+ is crucial for safeguarding both the environment and biosafety. In this study, an aptamer-based electrochemical sensor was developed for specific detection of Pb2+ by modifying a polylysine (PLL) coated silver-thiolated graphene (Ag-SH-G) nanocomposite (PLL/Ag-SH-G) on the surface of a glassy carbon electrode, which was further modified with gold nanoparticles (AuNPs) for attachment of aptamers (Apt) that specifically recognized Pb2+. The Ag-SH-G particles were synthesized using a one-step in situ method, resulting in significantly enhanced electrochemical properties upon incorporating Ag nanoparticles into the PLL/Ag-SH-G composite. Coating of the covalently or no-covalently bonded Ag-SH-G particles with PLL provides an excellent supporting matrix, facilitating the assembly of AuNPs and a thiol-modified aptamer for Pb2+. Under optimized conditions, Apt/AuNPs/PLL/Ag-SH-G/GCE exhibited excellent sensing performance for Pb2+ with a wide linear response range (10-1000 nM), a low detection limit (0.047 nM) and extraordinary selectivity. The sensor was employed and satisfactory results were obtained in river water, soil and vegetable samples for the detection of Pb2+.

Abstract
Ferroptosis is a new form of iron-dependent programmed cell death discovered in recent years, which is caused by the accumulation of lipid peroxidation (LPO) and reactive oxygen species (ROS). Recent studies have shown that cellular ferroptosis is closely related to tumor progression, and the induction of ferroptosis is a new means to inhibit tumor growth. Biocompatible Fe3O4 nanoparticles (Fe3O4-NPs), rich in Fe2+ and Fe3+, act as a supplier of iron ions, which not only promote ROS production but also participate in iron metabolism, thus affecting cellular ferroptosis. In addition, Fe3O4-NPs combine with other techniques such as photodynamic therapy (PDT); heat stress and sonodynamic therapy (SDT) can further induce cellular ferroptosis effects, which then enhance the antitumor effects. In this paper, we present the research progress and the mechanism of Fe3O4-NPs to induce ferroptosis in tumor cells from the perspective of related genes and chemotherapeutic drugs, as well as PDT, heat stress, and SDT techniques.

Abstract
Exosomes are extracellular vesicles that exist in body circulation as intercellular message transmitters. Although the potential of tumor-derived exosomes for non-invasive cancer diagnosis is promising, the rapid detection and effective capture of exosomes remains challenging. Herein, a portable electrochemical aptasensor of cubic AuPt dendritic nanocrystals (AuPt DNs)/Ti3C2 assisted in signal amplification, and aptamer CD63 modified graphene oxide (GO) was immobilized on a screen-printed carbon electrode (SPCE) as the substrate materials for the direct capture and detection of colorectal carcinoma exosomes. Cubic AuPt DNs/Ti3C2 was synthesized according to a simple hydrothermal procedure, and the AuPt DNs/Ti3C2-Apt hybrid demonstrated an efficient recognition of exosomes. Under optimal conditions, a detection limit of down to 20 exosomes µL-1 was achieved with the linear range from 100 exosomes μL-1 to 5.0 × 105 exosomes μL-1. The proposed immunosensor could be suitable for the analysis of exosomes and has clinical value in the early diagnosis of cancer.

Abstract
The outbreak of the coronavirus (COVID-19) has heightened awareness of the importance of quick and easy testing. The convenience, speed, and timely results from point-of-care testing (POCT) in all vitro diagnostic devices has drawn the strong interest of researchers. However, there are still many challenges in the development of POCT devices, such as the pretreatment of samples, detection sensitivity, specificity, and so on. It is anticipated that the unique properties of nanomaterials, e.g., their magnetic, optical, thermal, and electrically conductive features, will address the deficiencies that currently exist in POCT devices. In this review, we mainly analyze the work processes of POCT devices, especially in nucleic acid detection, and summarize how novel nanomaterials used in various aspects of POCT products can improve performance, with the ultimate aims of offering new ideas for the application of nanomaterials and the overall development of POCT devices.

Abstract
Abnormal miR-22 level is related to laryngeal squamous cell carcinoma (LSCC) progression. This study mainly assessed its role in proliferation, invasion and EMT of LSCC and their possible mechanisms of action. HN4 was collected, and corresponding groups were set as; blank group, positive
control group, miR-22 group and MIRNA-22 NC group. Pathway inhibitor group and pathway agonist group were also set. The expressions of miR-22, EMT-related genes, cell proliferation rate, invasion rate, β-catenin and Cyclin D1 were observed. Results revealed that, expressions of
miR-22 and e-cadherin were higher in the blank group and miR-22 NC group, while N-cadherin and Vimentin levels were lower. Moreover, miR-22 and EMT-related genes in the positive control group and miR-22 group were opposite (P <0.05). The proliferation rate and invasion rate of blank
and miR-22 NC groups were also lower, while positive control and miR-22 groups showed different changes (P <0.05). β-catenin and Cyclin D1 expressions in the blank group and miR-22 NC group were increased compared to other two groups. The proliferation rate, invasion
rate, expression of N-cadherin and Vimentin were higher and E-cadherin was lower in blank and pathway agonist group, which was opposite in the pathway inhibitor group (P < 0.05). β-catenin and Cyclin D1 protein levels in blank and pathway agonist groups were higher than
pathway inhibitor group (P < 0.05). A binding region between miR-22 gene sequence and 3′UTR 215-229 sequence of Wnt gene was found and Wnt was found to be the target gene for miR-22. The fluorescence intensity of mutant plasmid was higher than wild-type plasmid (P <0.05).
miR-22 can inhibit LSCC proliferation, invasion and EMT and the main mechanism of action is related to the Wnt signaling pathway. MiR-22 targeted Wnt gene and inhibited Wnt signaling pathway activity, lower key factor beta catenin expression Wnt pathways, thereby inhibiting factor laryngeal
squamous cancer cells proliferation, Cyclin D1 expression, resulting in inhibition of cell proliferation, and EMT process at the same time, reducing the cell invasion ability, inhibiting the growth of laryngeal squamous cancer cells. Eventually, the Wnt pathways or miR-22 all can be used as
targets for laryngeal squamous carcinoma.

Abstract
The aim of this paper was to combine transcriptomics and metabolomics to analyze the mechanism of gold nanoparticles (GNPs) on human dermal fibroblasts (HDFs). First, 20-nm GNPs were prepared, and the differentially expressed genes in HDFs were subsequently screened by transcriptome
sequencing technology after 4, 8, and 24 h of treatment with GNPs. By comparing the metabolic pathways in which the metabolites obtained in a previous study were involved, the pathways involving both genes and metabolites were filtered, and the differentially expressed genes and metabolites
with upstream and downstream relationships were screened out. The gene–metabolite–metabolic pathway network was further constructed, and the functions of metabolic pathways, genes and metabolites in the important network were analyzed and experimentally verified. The results of
transcriptome sequencing experiments showed that 1904, 1216 and 489 genes were differentially expressed in HDFs after 4, 8 and 24 h of treatment with GNPs, and these genes were involved in 270, 235 and 163 biological pathways, respectively. Through the comparison and analysis of the metabolic
pathways affected by the metabolites, 7, 3 and 2 metabolic pathways with genes and metabolites exhibiting upstream and downstream relationships were identified. Through analysis of the gene–metabolite–metabolic pathway network, 4 important metabolic pathways, 9 genes and 7 metabolites
were identified. Combined with the results of verification experiments on oxidative stress, apoptosis, the cell cycle, the cytoskeleton and cell adhesion, it was found that GNPs regulated the synthesis of downstream metabolites through upstream genes in important metabolic pathways. GNPs inhibited
oxidative stress and thus did not induce significant apoptosis, but they exerted effects on several cellular functions, including arresting the cell cycle and affecting the cytoskeleton and cell adhesion.

Abstract
The purpose of this paper is to explore the role and mechanism of N-Methyl-D-Aspartate (NMDA) receptors in the effects of silver nanoparticles (SNPs) on the electrical excitability of hippocampal neuronal networks. First, the cytotoxicity of different concentrations of SNPs was evaluated
and screened by MTT experiment, then the Voltage Threshold Measurement Method (VTMM) was employed to study the effects of SNPs on the electrical excitability of hippocampal neuronal networks under non-cytotoxic (5 μM) and cytotoxic (100 μM) concentrations after different
action times. The role of NMDA receptors in the effects of SNPs on the electrical excitability of hippocampal neuronal networks was investigated through the NMDA receptor antagonist MK-801. Then, the effects of SNPs on the number of NMDA receptors and the Ca2+ content in hippocampal
neurons were further investigated, and the relationship between these changes and neuronal networks electrical excitability was discussed. The results of voltage threshold (VTh) test showed that non-cytotoxic 5 μM SNPs has an excitatory effect on hippocampal neuronal
networks, while the effect of cytotoxic 100 μM SNPs gradually changed from excitatory to inhibitory with the extension of action time. It was found that SNPs could increase the electrical excitability of neuronal networks by activating NMDA receptors through the experiments with
MK-801 antagonists. Moreover, the fluorescent staining experiments showed that the activation of NMDA receptors by SNPs can lead to an increase in the intracellular Ca2+ content, and then trigger a negative feedback regulation mechanism of neurons between the number of NMDA receptors
and intracellular Ca2+ content. The high Ca2+ content in neurons can also decrease neurons’ cell viability, which in turn leads to changes in the electrical excitability of the neuronal networks.

Abstract
Diabetes, a global health concern, affects the health of more than 500 million adults. The absence of Notch protein can cause an imbalance in the retinal vascular environment and cause retinal vascular disease. Long noncoding RNA (lncRNA) is known to be involved in the regulation of many signaling pathways. We hope to understand the specific mechanism of apoptosis in retinal vascular endothelial cells (RVECs) by exploring the regulatory effect of lncRNA on the Notch pathway. In this study, we found that RVECs treated with glucose showed increased levels of Notch transcript and protein expression. The lentiviral interference with Notch RNAi reversed this response. When Notch activity decreased, oxidative stress also decreased, accompanied by increased levels of Caspase-9 and Caspase-3 and an increased rate of apoptosis. Therefore, we believe that Notch is involved in the development of diabetic retinopathy and loss of expression promotes apoptosis of human RVECs. By inhibiting the Notch pathway, lncRNA promotes apoptosis of human RVECs in a high-glucose environment.

Abstract
A simple and rapid genotyping method with less-instrumentation is essential for realizing point-of-care detection of personalized medicine-related gene biomarkers. Herein, we developed a rapid and visualized genotyping method by coupling recombinase polymerase amplification (RPA) with allele-specific invader reaction assisted gold nanoparticle probes assembling. In the method, the DNA targets were firstly amplified by using RPA, which is a rapid isothermal amplification technology. Then an allele-specific invasion reaction was performed to recognize the single nucleotide polymorphisms (SNPs) site in the amplicons, to produce signal molecules that caused discoloration of gold nanoparticle probes. As a result, genotyping was achieved by observing the color change of the reaction by using naked eye without the requirement for any expensive instrument. In order to achieve rapid genotyping detection, the genomic DNA from oral swab lysate samples were used for the RPA templates amplification. In this way, a visualized genotyping from "samples to results" within 25 min was realized. Two clopidogrel related SNPs CYP2C19*2 and CYP2C19*3 of 56 clinical samples were correctly genotyped by using this rapid visualized genotyping assay. In addition, the feasibility for this pathogen genotyping method was also verified by detecting plasmid DNA containing three SARS-COV-2 gene mutation sites, indicating that this method has the potential for clinical sample detection.

Abstract
This study aimed to investigate the role of the primary Fos-related antigen 1 (Fosl-1) oncogene in nephroblastoma by studying 60 childhood nephroblastoma and 58 paraneoplastic carcinoma cases. The Fosl-1 expression was detected using immunohistochemistry. In vitro culture of nephroblastoma cells was performed by viral transfection to establish Fosl-1 overexpression and gene knockout models. Flow cytometry and nano-PCR were used to detect apoptosis and mRNA expression in related pathway genes. Immunohistochemical results showed that the positive expression of Fosl-1 in the nuclei of nephroblastoma tissue was 78%, among which metastasis rate was 61.7%; correspondingly, it was 8%, and 100% in adjacent tissues. The qPCR results indicated that MMP9, Wnt1, and Fzd1 were significantly upregulated after Fosl-1 overexpression compared with the normal embryonic tissue cells, control, and gene knockout groups (P <0.05). Fosl-1 could cause the occurrence, development, and metastasis of childhood nephroblastoma through wingless/int1/Frizzled-related signaling pathways.

Abstract
This study investigated icariin (ICA) nanoparticles on angiogenesis in rats with pulmonary fibrosis and its mechanism. First, icariin solid nanoliposomes (ICA-SLN) were prepared. The in vitrorelease of icariin nanoparticles was determined using a UV-Vis spectrophotometer, after which the plasma concentration of icariin nanoparticles in rats was determined. The bioavailability of icariin nanoparticles was investigated, and the effect of icariin on angiogenesis of pulmonary fibrosis rats was re-observed. The results showed that the bioavailability of icariin in vivo was enhanced after nanomodification, which indicated that icariin solid nanoliposome was a good choice for oral sustained-release nanocarrier materials. in vivo experiments showed that icariin could significantly inhibit angiogenesis in rats with pulmonary fibrosis, and the inhibitory effect was related to the dose and time of action. Most importantly, this study provides the possibility of icariin as a targeted agent for future-targeted therapy.

Abstract
This study aimed to detect miR-455-5p and S1PR1 proteins using nanoparticle-assisted polymerase chain reaction (nano-PCR) to determine their correlation with cervical carcinoma prognosis. To achieve this study's goals, we selected 48 cervical carcinoma patients between January 2014 to January 2016 and subjected them to the miR-455-5p test by nano-PCR. The collected samples were then divided into two groups based on miR-455-5p levels. We had four HeLa cell groups, one group as the control, and one group overexpressed the miR-455-5p protein. A third group was miR-455-5p silent, and a separate group overexpressed both the miR-455-5p and S1PR1 proteins. Results also proved that the nano-PCR had a higher sensitivity than RT-PCR, and patients with poor prognosis had lesser miR-455-5p levels. Similarly, high levels of miR-455-5 contributed to cancer cell apoptosis and migration inhibition by targeting S1PR1 expression negatively. These two biomarkers are therefore significantly related to the prognosis of cervical carcinoma patients.

Abstract
In this work, an integrated electrode system consisting of a graphene working electrode, a carbon counter electrode and an Ag/AgCl reference electrode was fabricated on an FR-4 glass fiber plate by a polyethylene self-adhesive mask stencil method combined with a manual screen printing technique. The integrated graphene electrode was used as the base electrode, and AuNPs were deposited on the working electrode surface by cyclic voltammetry. Then, the carcinoembryonic antigen aptamer was immobilized using the sulfhydryl self-assembly technique. The sensor uses [Fe(CN)6]3-/4- as a redox probe for label free detection of carcinoembryonic antigen based on the impedance change caused by the difference in electron transfer rate before and after the binding of carcinoembryonic antigen aptamer and the target carcinoembryonic antigen. The results showed a good linear relationship when the CEA concentration is in the range of 0.2-15.0 ng/ml. The detection limit was calculated to be 0.085 ng/ml (S/N = 3).

Abstract
Neuroglioma is the most common malignant tumor in the central nervous system and still has a poor prognosis. Here, we investigated the prognostic value of long non-coding RNAs(lncRNAs) in glioblastoma. We first analyzed the lncRNA expression profiles of glioblastoma (GBM) in The Cancer
Genome Atlas database and selected the most differential survival genes (lncRNA RP4-669H2.1) for further validation. We then performed qRT-PCR using samples of 88 glioblastoma patients treated in our department between January 2011 and December 2017 that were retrospectively selected to validate
the prognostic value of RP4-669H2.1expression in glioblastoma. Using a Cox multivariate analysis, we explored the prognostic value of RP4-669H2.1 and analyzed whether it was an independent prognostic factor. This analysis confirmed that the RP4-669H2.1 expression was significantly associated
with glioblastoma-associated mortality in this patient cohort (P =1.80E–05) in TCGA database. In fact, the overall survival (OS) of the RP4-669H2.1 high-expression group (78 cases) was lower than that of the low-expression group (49 cases) (P = 4.6E–06) in TCGA database.
Moreover, the TNM stage of the RP4-669H2.1 high-expression group was higher than that of the RP4-669H2.1 low-expression group (P = 0.001). A multivariate analysis further showed that a higher TNM stage (OR = 2.167, 95% CI: 1.349–3.479) and a higher RP4-669H2.1 expression (OR =
2.933, 95% CI: 1.122–7.663) were independent risk factors for the OS of glioblastoma patients. Finally, we predicted the target genes of RP4-669H2.1 using a Multi Experiment Matrix and annotated their biological functions. We observed that the target genes of RP4-669H2.1 were mainly
enriched in biological functions related to DNA-binding transcription factor activity. Among these, we selected SMAD6 because the expression of RP4-669H2.1 was positively correlated with that of SMAD6 in glioblastoma. Overall, we conclude that the upregulation of RP4-669H2.1 is an independent
poor prognosis factor for glioblastoma and that it can regulate the DNA-binding activity of transcription factors.

Abstract
A novel approach for the detection of influenza virus is of paramount importance for quick diagnosis and therapy. In this study monoclonal antibody (mAb)-conjugated MNPs/AuNPs were developed to detect the H1N1 virus. MNPs and AuNPs were synthesized and loaded with
mAbs. The UV-vis spectra exhibited absorbance at 528 nm. XRD revealed the presence of crystalline particles with various diffraction peaks. FTIR confirmed the occurrence of capping molecules in the synthesized NPs. NP stability was evidenced by zeta measurements. The shape and size (mean size
15 nm) of the NPs were determined using SEM and transmission electron microscopy (TEM). In this study the mAb–AuNPs produced a redshift in the absorption spectrum due to plasmon coupling. The absorption increased when H1N1 concentration increased from 0 to 5.0 ng/mL,
with the detection limit being 0.05 ng/mL. The sensitivity of mAb–AuNPs was greater than that of ELISA. Since the mAb-AuNP-based colorimetric immunosensor is simple, cost-effective, and rapidly detects H1N1, it has good prospects in pharmaceuticals and clinical
diagnosis.

Abstract
Lactobacillus brevis is the most common bacteria that causes beer spoilage. In this work, a novel electrochemical immunosensor was fabricated for ultra-sensitive determination of L. brevis. Gold nanoparticles (AuNPs) were firstly electro-deposited on the electrode surface for enhancing the electro-conductivity and specific surface area. Ionic liquid was used for improving the immobilization performance of the immunosensor. After optimization, a linear regression equation can be observed between the ∆current and concentration of L. brevis from 104 CFU/mL to 109 CFU/mL. The limit of detection can be estimated to be 103 CFU/mL.

Abstract
The content of cardiac troponin I (CTnI) in human blood is the key factor in judging acute myocardial infarction (AMI). In order to detect the content of CTnI, we constructed a sandwich-type electrochemical immunosensor based on hydrogen peroxide (H2O2) as a signal source. Dendritic platinum-copper alloy nanoparticles (DPCN) loaded on molybdenum disulfide (MoS2) nanosheets (DPCN/MoS2) as secondary antibodies (Ab2) label provided signal amplification. The hollow three-dimensional (3D) pyramid-shaped structure of DPCN exposed abundant active sites and exhibited excellent catalytic properties. MoS2 nanosheets with flower-like structure and a larger specific surface area can effectively load more DPCN. The combination of MoS2 and DPCN enhanced the catalytic performance of DPCN/MoS2 towards H2O2 reduction and realized signal amplification. For the substrate material, the two-dimensional (2D) metal-organic framework (Co-BDC, 1,4-benzenedicarboxylate is abbreviated as BDC) was hybridized with MoS2 nanosheets to load gold nanoparticles (Au NPs). The obtained Au/Co-BDC/MoS2 had low catalytic activity and excellent electrical conductivity, which was used to load primary antibodies (Ab1) to effectively enhance the sensitivity. Under the best conditions, we constructed the immunosensor with the detection range of 10 fg/mL to 100 ng/mL and the limit of detection (LOD) of 3.02 fg/mL. At the same time, the content of CTnI in human serum was tested with satisfactory results. Therefore, the constructed immunosensor has important significance in the sensitive and accurate detection of CTnI and early diagnosis of AMI.

Abstract
Sandwich-type electrochemical immunosensor was one of the main methods for detecting carcinoembryonic antigen (CEA). In this work, using Ce-MoF as the skeleton precursor, hyaluronic acid (HA) was coated on the surface of Ce-metal organic framework (Ce-MoF), which loaded with silver nanoparticles (Ag NPs) and horseradish peroxidase (HRP) to catalyze H2O2 and double amplified the current signal. Thus, a sensitive sandwich-type electrochemical immunosensor (Ce-MoF@ HA/Ag-HRP) was designed to detect carcinoembryonic antigen (CEA). The designed immunosensor used Au NPs to enhance the ability of attach more the first antibody (Ab1). This was due to Au NPs had good electrical conductivity and biocompatibility to accelerate electron transfer on the surface of the electrode. HA was riched in -COOH, -OH and had excellent biocompatibility, which can carry more Ag NPs to catalyze H2O2. Finally, the prepared sandwich-type electrochemical immunosensor had excellent biocompatibility and great catalytic performance. The immunosensor can be tested within 30 min and the logarithm of the current signal and CEA concentration showed a broad linear response range of 1 pg ml-1-80 ng ml-1, and the detection limit of CEA was 0.2 pg ml-1. More importantly, the proposed immunosensor had good reproducibility, selectivity, stability and without matrix effect. This confirmed that the proposed immunosensor had broad prospects in early clinical trials.

Abstract
A sensitive sandwich-type electrochemical immunosensor was established by employing Au@Pt core-shell multi-branched nanoparticles, and thionin functionalized nitrogen/sulfur co-doped graphene oxide (N/S-cGO/L-lys/Au@Pt MBs/Thi) as a double signal label to detect cardiac troponin I (cTnI). In this work, Au nanorods functionalized polydopamine (Au NR@PDA) with high adsorption capacity and superior electroconductivity can provide an efficient substrate for immobilizing primary antibodies (Ab1). In the proposed N/S-cGO/L-lys/Au@Pt MBs/Thi, an electrochemically active molecule, Thi was covalently bonded in the N/S-cGO/L-lys/Au@Pt MBs. It presented a strong differential pulse voltammetry (DPV) current signal without electron transfer mediators, and showed a high electrocatalytic activity toward H2O2 reduction by using amperometric i-t (i-t). Impressively, with the synergistic effect of N/S-cGO/L-lys/Au@Pt MBs/Thi and Au NR@PDA, the developed dual-mode electrochemical immunosensor for cTnI detection showed a wide linear concentration range (50 fg/mL to 250 ng/mL, 750 fg/mL to 100 ng/mL) and a low detection limit (16.7 fg/mL, 250 fg/mL) via i-t and DPV, respectively. Furthermore, this immunosensor exhibited acceptable reproducibility, high sensitivity and good stability under optimal conditions. More importantly, the satisfactory results were obtained in detection of cTnI-spiked human serum samples, and the presented method may be a promising application in clinical bioanalysis.
