Abstract
DNA walking machines have achieved significant breakthroughs in areas such as biosensing, bioimaging, and early cancer diagnosis, facilitated by the self-assembly of DNA or its combination with other materials, such as magnetic beads and metal nanoparticles. However, current DNA walking machine strategies are constantly challenged by inadequate analytical sensitivity, while sophisticated signal amplification procedures are often indispensable. Single-particle inductively coupled plasma mass spectrometry (SP-ICPMS) provides superior sensitivity and can effectively discriminate between background noise and detected signals due to the large number of metal atoms in a nanoparticle and the concentrating effect of single nanoparticle detection. In this study, we present a novel approach utilizing single nanoparticle counting and duplex-specific nuclease (DSN)-assisted signal amplification to construct a 3D DNA walking machine for detecting the aggressive prostate cancer (PCa) biomarker miRNA-200c. The proposed strategy showed an improvement in sensitivity with a detection limit (LOD) of 0.93 pM (28 amol) and was successfully applied in human serum samples. To the best of our knowledge, this is the first report of the DNA walking machine with single nanoparticle counting study.

Abstract
CRISPR (clustered regularly interspaced short palindromic repeats) and CRISPR-associated protein (Cas) have gained extensive applications in bioassays. However, CRISPR-based detection platforms are often hampered by limited analytical sensitivity, while nucleic acid-based amplification strategies are usually indispensable for additional signal enhancement with potential risks of amplification leakages. To address these challenges, an amplification-free CRISPR-based bioassay of aflatoxin B1 (AFB1) was proposed by applying single nanoparticle counting. Single-particle mode inductively coupled plasma mass spectrometry (Sp-ICPMS) has been regarded as a sensitive tool for nanoparticle counting since one nanoparticle can generate considerable signals above backgrounds. With AFB1, activator strands were introduced to initiate the trans-cleavage of CRISPR/Cas12a for cutting the nanoparticles-tagged-magnetic beads, which were transduced to nanoparticle count signals after separation. Finally, a pico-mole level limit-of-detections (LODs) with moderate selectivity was achieved. Certified reference materials (CRMs) analysis and recovery tests were conducted with promising results. To our best knowledge, this is the first report of the single particle counting-based CRISPR/Cas12a biosensing study.

Abstract
Bioassays using inductively coupled plasma mass spectrometry (ICP-MS) have gained increasing attention because of the high sensitivity of ICP-MS and the various strategies of labeling biomolecules with detectable metal tags. The classic strategy to tag the target biomolecules is through direct antibody-antigen interaction and DNA hybridization, and requires the separation of the bound from the unbound tags. Label-free ICP-MS techniques for biomolecular assays do not require direct labeling: they generate detectable metal ions indirectly from specific biomolecular reactions, such as enzymatic cleavage. Here, we highlight the development of three main strategies of label-free ICP-MS assays for biomolecules: (1) enzymatic cleavage of metal-labeled substrates, (2) release of immobilized metal ions from the DNA backbone, and (3) nucleic acid amplification-assisted aggregation and release of metal tags to achieve amplified detection. We briefly describe the fundamental basis of these label-free ICP-MS assays and discuss the benefits and drawbacks of various designs. Future research is needed to reduce non-specific adsorption and minimize background and interference. Analytical innovations are also required to confront challenges faced by in vivo applications.

Abstract
DNA walkers, artificial dynamic DNA nanomachines, can mimic actin to move rapidly along a predefined nucleic acid track. They can generally be classified as one- (1D), two- (2D), and three-dimensional (3D) DNA walkers. In particular, 3D DNA walkers demonstrate amazing sustainable walking ability, strong enrichment ability, and fantastic signal amplification ability. In light of these, 3D DNA walkers have been widely used in fields such as biosensors, bioanalysis and cell imaging. Most notably, the strong compatibility of 3D DNA walkers allows their integration with a range of amplification strategies, effectively enhancing signal transduction and amplifying biosensor sensing signals. Herein, we first systematically expound the walking principle of the 3D walkers in this review. Then, by presenting representative examples, the research direction of 3D walkers in recent years is discussed. Furthermore, we also categorize and evaluate diverse tandem signal amplification strategies in 3D walkers. Finally, the challenges and development trends of 3D DNA walkers in the emerging field of analysis are carefully discussed. It is believed that this work can provide new ideas for researchers to quickly understand 3D DNA walkers and their applications in diverse biosensors.

Abstract
Considerable advances have been made in the design, modularization, functionalization, and regulation of DNA nanostructures over the past 40 years. These advances have accelerated the development of DNA nanomachines such as DNA walkers, dynamic nanomachines with walking feet, tracks, and driven forces, which have highly sensitive detection and signal amplification abilities that can be applied to various bioanalytical contexts and therapeutic strategies. Here, we describe a rational design of the nano-bio interface, the kinetics of DNA walkers and the strategies for improving their efficiency and sensitivity. We also outline the various bioanalytic and imaging applications to which DNA walkers have been applied, such as electrochemical and optical measurements, when integrated with other simulation and activation tools. Finally, we compare the performances of novel DNA walker-based strategies for bioanalysis and propose a method to improve DNA walker design.

Abstract
Biomimetic DNA walking machines have gained great success in scrutinizing the microscopic world and sensitive biosensing of disease biomarkers. Despite superb achievements, the research on DNA walking machines for simultaneous detection of multiple analytes is still rare, while the design and realization of multiplexing are considered as an important bottleneck. The multiplex detection of biomarkers can not only improve the specificity of bioassays but also avoid the squander of valuable biological specimens. Herein, we reported multiplex three-dimensional (3D) DNA walking machines based on high-resolution inductively coupled plasma mass spectrometry (HR-ICPMS) for lung cancer-associated miRNA detection. In the presence of lung cancer-associated target miRNAs (miR-21, miR-141, and miR-125b), DNA walking machines were stimulated and operated to liberate a large number of lanthanide elements (Tb, Ho, and Tm), and then the signals were collected simultaneously by HR-ICPMS. The recovery test of target miRNAs in human serum and the simultaneous monitoring experiment of three miRNAs in human lung cancer cell line (A549) and normal cell line (HBE) specimens display satisfactory analysis capabilities for complex biological samples. Thanks to the vast potential of lanthanide tags and the modular design, the proposed bioassay might flexibly detect different miRNA combinations with corresponding sets of DNA walking machines to meet the requirements of various tasks.

Abstract
Metal stable isotope tagging has demonstrated great and unique success in the multiplex and ratiometry-based accurate detection of biomolecules and single cells, while its sensitivity is regarded as an Achilles' heel. Although lanthanide nanoparticles remain the most promising tags for elemental mass spectrometry, there is no report on the lanthanide nanoparticle-based multiplex immunoassay of disease markers in clinical serum samples because of their tough synthesis and bioconjugation and a complex physiological sample matrix. Herein, to fill this gap, multiple lanthanide nanoparticle tags (NaEuF4, NaTbF4, and NaHoF4) were delicately designed and facilely synthesized with a one-pot solvothermal method for the multiplex evaluation of breast cancer biomarkers carcinoembryonic antigen (CEA), CA153, and CA125 in human serum samples. The proposed method exhibited wide linear ranges and low levels of the detection limit for all biomarkers. The test results were consistent with the routine electrochemiluminescence results in clinical serum samples, which proved the possibility of the early prognosis of breast cancer as well as improving the surgical outcome prediction.

An "off-on" electrochemiluminescence biosensor coupled with strand displacement-powered 3D micromolecule walking nanomachine for ultrasensitive detection of adenosine triphosphate.

Abstract
A three-dimensional (3D) micromolecule walking nanomachine propelled by strand displacement was developed to establish a novel switching electrochemiluminescence (ECL) biosensor for ultrasensitive detection of adenosine triphosphate (ATP). Generally, walking nanomachines reported previously were limited to DNA walkers, while the proposed 3D walking nanomachine focused on the micromolecule walker. Firstly, TiO2 and silver nanoparticles (Ag NPs) functionalized N-(4-aminobutyl)-N-(ethylisoluminol) (Ag-ABEI) were deposited onto the electrode surface to offer an enhanced ECL signal, resulting from the double catalytic effect of TiO2 and Ag NPs for H2O2. Following, dopamine (DA)-labeled DNA duplex probes (S1/S2-DA) immobilized onto the modified electrode cut down the original ECL signal due to the quenching of DA toward ABEI (signal-off). Target ATP walker moved along the 3D DNA track, simultaneously releasing numerous DNA3, which was applied to displace S2-DA, resulting in the quenched ECL intensity recovery (signal-on). As a result, the biosensor showed a low limit of detection down to 0.5 nM (S/N = 3) and was successfully employed to determine ATP in human serum samples. Thus, the established biosensing strategy holds great potential for biochemical studies and clinical diagnosis.

Abstract
MicroRNA (miRNA), of which the abnormal intracellular expression highly associates with numerous pathological diseases, is considered as an important biomarker for early diagnosis and state monitoring of cancer. To avoid the tedious and vunerable labeling process, a series of novel label-free quantification methods for miRNA have been proposed. However, current label-free miRNA assays still require the presynthesis of a sensing unit as tags. Herein, we propose a "tag-free" methodology for miRNA quantification to realize the removal of sensing labels. Combining a concatenated-HCR (C-HCR) strategy and high-resolution inductive couple plasma mass spectrometry (HR-ICPMS) detection, we utilize phosphorus as a characteristic element to quantify the concentration of nucleotides. Benefiting from the excellent amplification performance of C-HCR and element analysis capacity of HR-ICPMS, a 13 fM limit of detection (LOD) was obtained. Ulteriorly, we verify the anti-interference performance of the proposed tag-free miRNA assay with a phosphate substrate-contained cell culture medium or nontarget miRNA. Furthermore, two cell lines of human cancer were chosen to evaluate the real biological sample analysis capacity. The good correlation data indicate promising prospects of the proposed tag-free methodology for the quantification of miRNA in tumor cells and further clinical applications.
