[PMID: 37651915 DOI: 10.1016/j.talanta.2023.125131] [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: 05/30/2023] [Revised: 08/23/2023] [Accepted: 08/25/2023] [Indexed: 09/02/2023]
Abstract
Apolipoprotein A4 has a wide range of synaptic toxicity and can be used as a reliable molecular biomarker for the detection of depressive disorder. It has certain clinical requirements for simple, rapid and selective detection of apolipoprotein A4. Here, based on the DNA biped walker driven by DNAzyme, we designed a label-free surface-enhanced Raman scatting sensor for rapid detection of apolipoprotein A4. Compared with the typical DNA walker, the biped DNA walker has the advantages of large walking range and high magnification efficiency. The magnesium-dependent DNAzyme drives the DNA walker, which can cut the MBs sequentially. The resulting MBs fragments were then hybridized with AuNPs modified by repetitive adenine to make Au NPs proliferate on the substrate surface, resulting in a large number of cycles. Using 736 cm-1 adenine as the internal marker, surface enhanced Raman scattering analysis showed that the linear detection range of human apolipoprotein A4 was 10∼1000 ng mL-1, the detection limit was 4.7 pg/mL, and it had significant specificity, which could meet the needs of clinical detection and showed great application potential.

Abstract
Microarrays are one of the trailblazing technologies of the last two decades and have displayed their importance in all the associated fields of biology. They are widely explored to screen, identify, and gain insights on the characteristics traits of biomolecules (individually or in complex solutions). A wide variety of biomolecule-based microarrays (DNA microarrays, protein microarrays, glycan microarrays, antibody microarrays, peptide microarrays, and aptamer microarrays) are either commercially available or fabricated in-house by researchers to explore diverse substrates, surface coating, immobilization techniques, and detection strategies. The aim of this review is to explore the development of biomolecule-based microarray applications since 2018 onwards. Here, we have covered a different array of printing strategies, substrate surface modification, biomolecule immobilization strategies, detection techniques, and biomolecule-based microarray applications. The period of 2018–2022 focused on using biomolecule-based microarrays for the identification of biomarkers, detection of viruses, differentiation of multiple pathogens, etc. A few potential future applications of microarrays could be for personalized medicine, vaccine candidate screening, toxin screening, pathogen identification, and posttranslational modifications.

Abstract
CRISPR-based biosensors have attracted increasing attention in accurate and sensitive nucleic acid detection. In this work, we report a CRISPR/Cas12a-triggered chemiluminescence enhancement biosensor for the ultrasensitive detection of nucleic acids by introducing tyramide signal amplification for the first time (termed CRICED). The hybrid chain DNA (crDNA) formed by NH2-capture DNA (capDNA) and biotin-recognition DNA (recDNA) was preferentially attached to the magnetic beads (MBs), and the streptavidin-HRP was subsequently introduced to obtain MB@HRP-crDNA. In the presence of the DNA target, the activated CRISPR/Cas12a is capable of randomly cutting initiator DNA (intDNA) into vast short products, and thus the fractured intDNA could not trigger the toehold-mediated DNA-strand displacement reaction (TSDR) event with MB@HRP-crDNA. After the addition of tyramine-AP and H2O2, abundant HRP-tyramine-AP emerges through the covalent attachment of HRP-tyramine, exhibiting enhanced chemiluminescence (CL) signals or visual image readouts. By virtue of this biosensor, we achieved high sensitivity of synthetic DNA target and amplified DNA plasmid using recombinase polymerase amplification (RPA) as low as 17 pM and single-copy detection, respectively. Our proposed CRICED was further evaluated to test 20 HPV clinical samples, showing a superior sensitivity of 87.50% and specificity of 100.00%. Consequently, the CRICED platform could be an attractive means for ultrasensitive and imaging detection of nucleic acids and holds a promising strategy for the practical application of CRISPR-based diagnostics.

Chemiluminescent screening of specific hybridoma cells via a proximity-rolling circle activated enzymatic switch. Commun Biol 2022; 5:308.

Abstract
The mass-production capability of hybridoma technology is bottlenecked by the routine screening procedure which is time-consuming and laborious as the requirement of clonal expansion. Here, we describe a 1-day chemiluminescent screening protocol for specific hybridoma cells on conventional 96-well plate via a proximity-rolling circle activated enzymatic switch (P-RCAES) strategy. The P-RCAES uses a pair of antigen-DNA probes to recognize secreted specific antibody and proximity-induce rolling circle amplification for mass-production of pyrophosphate to activate Cu(II) inhibited horseradish peroxidase and generate a strong chemiluminescent signal. The P-RCAES based homogeneous chemiluminescent assay can detect antibody down to 18 fM, and enables the screening of specific hybridoma cells secreting PCSK9 antibody at single-cell level without tedious cloning process. The proposed fast screening protocol has good expansibility without need of sophisticated instruments, and provides a screening method for greatly improving the efficiency of hybridoma technology. In order to realize fast screening of specific hybridoma cells in hybridoma technology, a 1-day chemiluminescent screening method is reported on common 96-well plate via a proximity-rolling circle activated enzymatic switch strategy.

Abstract
In this work, we structured a colorimetric ultrasensitive detection of carcinoembryonic antigen (CEA) based on a proximity hybridization-induced gold nanoparticles (Au NPs) dimers structure. Under the dark-field microscope, this method takes advantage of the distinctive and strong distance-relative localized surface plasmon resonance (LSPR) of Au NPs and their oriented assembly. DNA served as a medium showing wonderful flexibility to label antibody and Au NPs, and tune interparticle spacing as well. Two capture probes were formed by the integration of DNA labeled antibody (DNA1-Ab1 or DNA2-Ab2) and asymmetrically assembled DNA (DNA 3 or DNA 4)- Au NPs via partly hybridization between DNA sequences. In the presence of antigen, the reaction between target protein and capture probes could trigger the generation of immunocomplex which led to the proximity hybridization of the DNA1 and DNA2, and then change the distance of interparticle to form Au NP dimers and thus showed a different color under dark-field microscope. A limit of detection of 14.25 pg/mL was obtained for the detection of CEA, which indicated a promising sensing method in clinical diagnosis of protein biomarkers.

Abstract
Proteins are generally detected as biomarkers for tracing or determining various disorders in organisms. Biomarker proteins can be tracked in samples with various origins and in different concentrations, revealing whether an organism is in a healthy or unhealthy state. In regard to detection, electrochemical biosensors are a potential fusion of electronics, chemistry, and biology, allowing for fast and early point-of-care detection from a biological sample with the advantages of high sensitivity, simple construction, and easy operation. Peptides present a promising approach as a biorecognition element when connected with electrochemical biosensors. The benefits of short peptides lie mainly in their good stability and selective affinity to a target analyte. Therefore, peptide-based electrochemical biosensors (PBEBs) represent an alternative approach for the detection of different protein biomarkers. This review provides a summary of the past decade of recently proposed PBEBs designed for protein detection, dividing them according to different protein types: (i) enzyme detection, including proteases and kinases; (ii) antibody detection; and (iii) other protein detection. According to these protein types, different sensing mechanisms are discussed, such as the peptide cleavage by a proteases, phosphorylation by kinases, presence of antibodies, and exploiting of affinities; furthermore, measurements are obtained by different electrochemical methods. A discussion and comparison of various constructions, modifications, immobilization strategies and different sensing techniques in terms of high sensitivity, selectivity, repeatability, and potential for practical application are presented.

Abstract
The morphological and mechanical properties of thiolated ssDNA films self-assembled at different ionic strength on flat gold surfaces have been investigated using Atomic Force Microscopy (AFM). AFM nanoshaving experiments, performed in hard tapping mode, allowed selectively removing molecules from micro-sized regions. To image the shaved areas, in addition to the soft contact mode, we explored the use of the Quantitative Imaging (QI) mode. QI is a less perturbative imaging mode that allows obtaining quantitative information on both sample topography and mechanical properties. AFM analysis showed that DNA SAMs assembled at high ionic strength are thicker and less deformable than films prepared at low ionic strength. In the case of thicker films, the difference between film and substrate Young’s moduli could be assessed from the analysis of QI data. The AFM finding of thicker and denser films was confirmed by X-Ray Photoelectron Spectroscopy (XPS) and Spectroscopic Ellipsometry (SE) analysis. SE data allowed detecting the DNA UV absorption on dense monomolecular films. Moreover, feeding the SE analysis with the thickness data obtained by AFM, we could estimate the refractive index of dense DNA films.

Abstract
A chemiluminescence (CL) system with long persistent and intensive emission is essential for accurate CL quantitative analysis and imaging assay. However, with most known CL systems being flash-type, it is still a great challenge to develop long-lasting CL systems. Here, by combining an iron porphyrin metal-organic frameworks (FePorMOFs) based peroxidase mimic with natural glucose oxidase (GOx), an intensive and persistent CL system is presented on the basis of local tandem catalysis and surface diffusion of the nano-/bioenzymes (FePorMOF/GOx). FePorMOF synthesized by iron porphyrin linker and zirconium ion node possesses high peroxidase catalytic activity and stability. Using luminol and glucose as substrate, the FePorMOF/GOx CL system can produce intensive CL emission containing a plateau period of 7.5 h. The strong CL signal is due to the local tandem generation and reaction of H2O2 by GOx and FePorMOF, which avoids the diffusion-limited kinetics and leads to a high catalytic efficiency of the nano-/bioenzymes. On the other hand, the long persistent CL emission is attributed mainly to the enzymatic reaction-controlled H2O2 supply and surface diffusion-controlled CL reaction. The proposed CL system is explored for CL imaging sensing of glucose and homogeneous immunoassay of α-fetoprotein. The nano-/bioenzymes CL system exhibits intensive and long constant CL emission in physiological condition, showing promising applications in real-time bioassay and bioimaging.

Abstract
This work designed an anchored monopodial DNA walker to amplify amperometric biosensing signal for sensitive detection of nucleic acid and protein. The biosensing surface was constructed by self-assembling hairpin DNA1 (H1) and small amount of P1-W (probe DNA1 hybridized with walking DNA) on a gold electrode. In the presence of target molecule, the walker could be triggered by the surface proximity hybridization product of P1, target and P2 to induce the cyclic hybridization of H1 with ferrocene modified hairpin DNA2 (H2-Fc), which took electroactive Fc to the electrode surface for amplified amperometric detection of the target. By linking P1 and P2 with dual specific DNA strands, aptamers or antibodies to recognize the target for proximity hybridization of P1 and P2, the walker amplified amperometric strategy could be used for highly sensitive biosensing of different targets. Using DNA and thrombin as the target models, the proposed biosensing methods achieved the linear range from 0.2 pM to 2 nM with a detection limit of 0.11 pM and 1.0 pM to 10 nM with a detection limit of 0.61 pM, respectively. The specific recognition process endowed the strategy with high selectivity and potential applications.

Abstract
In the present study, a tetrahedron probe with encoded internal reference nanoparticles (NPs) was self-assembled by a complementary nucleic acid aptamer for simultaneous ratiometric detection of telomerase (TE) and epithelial cell-adhesion molecule (EpCAM) in living cells. In the presence of a target, the dissociation of gold (Au) NPs, which was modified with corresponding tags, resulted in decreased surface-enhanced Raman scattering (SERS) signals. In addition, the ratios of Raman intensity at 1346 cm-1/1096 cm-1 (TE) and 1614 cm-1/1096 cm-1 (EpCAM) compared with the internal reference were demonstrated to quantify the level of TE and EpCAM, respectively, and can eliminate certain background noise. A good linear relationship was observed between them, and the linear range of TE and EpCAM in HeLa cells was 0.7 × 10-12 to 37.5 × 10-12 IU and 1.24 to 75.48 pg/mL with a limit of detection (LOD) of 7.6 × 10-16 IU and 0.53 pg/mL, respectively, which were consistent with the results of Raman confocal imaging. Meanwhile, the versatility and specificity of the developed probes were confirmed in cell lines. These results provide a reliable and ultrasensitive strategy for the in situ detection of biomarkers and a new method for SERS-based tetrahedrons in the early diagnosis of cancer.

Abstract
Nanomaterial-enabled chemiluminescence (CL) detection has become a growing area of interest in recent years. We review the development of nanomaterial-based CL detection strategies and their applications in bioanalysis. Much progress has been achieved in the past decade, but most attempts still remain in the proof-of-concept stage. This review highlights recent advances in nanomaterials in CL detection and organizes them into three groups based on their role in detection: as a sensing platform, as a signal probe, and applications in homogeneous systems. Furthermore, we have discussed the critical challenges we are facing and future prospects of this field.

Abstract
A simple proximity hybridization-induced on particle DNA walker was designed for ultrasensitive detection of proteins, for example platelet-derived growth factor (PDGF-BB) secreted by cancer cells, in which the DNA walker was activated by specific target binding and powered by an enzymatic cleavage to produce amplified signal. High-density FAM-labeled hairpin oligonucleotides (FAM-DNA1) were functionalized on AuNPs to construct three-dimensional (3D) DNA tracks. The specific binding of PDGF-BB with two aptamer probes (DNA3 and DNA4) led to the proximity hybridization-induced DNA displacement and the free of DNA walker (DNA2) to perform movement on the 3D tracks by an enzymatic cleavage, resulting in the release of massive FAM-DNA1 fragments from the AuNPs and the generation of fluorescent signal. This DNA walker based sensing strategy could detect PDGF-BB in a concentration range of 4 orders of magnitude with a detection limit down to sub-pM level. The practical applicability of the assay was demonstrated by detecting PDGF-BB secreted from MCF-7 cells with satisfactory results. The proposed DNA walker based assay could conveniently detect PDGF-BB with high sensitivity and good accuracy, along with the good extensibility of the assay, showing promise for practical diagnosis.

Abstract
Molecular logic gates play an important role in many fields and DNA-based logic gates are the basis of DNA computers. A dynamically NAND gate system on the DNA origami template is established in this paper. Naturally, the system is stable in solution without any reaction. Different logical values are mapped into different DNA input strands. When logical values are entered into the system, the corresponding DNA input strands undergo a directed hybridization chain reaction (HCR) at corresponding positions on the DNA origami template. The operation results are identified by disassembly between the nanogold particles (AuNPs) and DNA origami template. The nanogold particles remain on the DNA origami template, indicating that the result is true; The nanogold particles are dynamically separated from the DNA origami template, indicating that the result is false. The simulation of the system through Visual DSD shows that the reaction strictly followed the designed direction, and no error products are generated during the reaction. These simulation results show that the system has the advantages of feasibility, stability and intelligence.
