Abstract
Although DNA probes have attracted increasing interest for precise tumor cell identification by imaging intracellular biomarkers, the requirement of commercial transfection reagents, limited targeting ligands, and/or non-biocompatible inorganic nanostructures has hampered the clinic translation. To circumvent these shortcomings, a reconfigurable ES-NC (Na+-dependent DNAzyme (E)-based substrate (S) cleavage core/shell DNA nanocluster (NC)) entirely from DNA strands is assembled for precise imaging of cancerous cells in a successive dual-stimuli-responsive manner. This nanoprobe is composed of a strung DNA tetrahedral satellites-based protective (DTP) shell, parallelly aligned target-responsive sensing (PTS) interlayer, and hydrophobic cholesterol-packed innermost layer (HCI core). Tetrahedral axial rotation-activated reconfiguration of DTP shell promotes the exposure of interior hydrophobic moieties, enabling cholesterol-mediated cellular internalization without auxiliary elements. Within cells, over-expressed glutathione triggers the disassembly of the DTP protective shell (first stimulus), facilitating target-stimulated signal transduction/amplification process (second stimuli). Target miRNA-21 is detected down to 10.6 fM without interference from coexisting miRNAs. Compared with transfection reagent-mediated counterpart, ES-NC displays a higher imaging ability, resists nuclease degradation, and has no detectable damage to healthy cells. The blind test demonstrates that the ES-NC is suitable for the identification of cancerous cells from healthy cells, indicating a promising tool for early diagnosis and prediction of cancer.

Abstract
Until now, morphological assessment with an optical or electronic microscope, fluorescence in situ hybridization, DNA sequencing, flow cytometry, polymerase chain reactions, and immunohistochemistry have been employed for leukemia identification. Nevertheless, despite their numerous different vantages, it is difficult to recognize leukemic cells correctly. Recently, the electrochemical evaluation with a nano-sensing interface seems an attractive alternative. Electrochemical biosensors measure the modification in the electrical characteristics of the nano-sensing interface, which is modified by the contact between a biological recognition element and the analyte objective. The implementation of nanosensors is founded not on single nanomaterials but rather on compilating these components efficiently. Biosensors able to identify the molecules of deoxyribonucleic acid are defined as DNA biosensors. Our review aimed to evaluate the literature on the possible use of electrochemical biosensors for identifying hematological neoplasms such as acute promyelocytic leukemia, acute lymphoblastic leukemia, and chronic myeloid leukemia. In particular, we focus our attention on using DNA electrochemical biosensors to evaluate leukemias.

Fluorescent Aptasensor for Highly Specific Detection of ATP Using a Newly Screened Aptamer. SENSORS 2022; 22:s22072425. [PMID: 35408040 PMCID: PMC9003339 DOI: 10.3390/s22072425] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 03/17/2022] [Accepted: 03/19/2022] [Indexed: 11/16/2022]
Abstract
Owing to the significant roles of adenosine triphosphate (ATP) in diverse biological processes, ATP level is used to research and evaluate the physiological processes of organisms. Aptamer-based biosensors have been widely reported to achieve this purpose, which are superior in their flexible biosensing mechanism, with a high sensitivity and good biocompatibility; however, the aptamers currently used for ATP detection have a poor ability to discriminate ATP from adenosine diphosphate (ADP) and adenosine monophosphate (AMP). Herein, an ATP-specific aptamer was screened and applied to construct a fluorescent aptasensor for ATP by using graphene oxide (GO) and strand displacement amplification (SDA). The fluorescence intensity of the sensor is linearly related to the concentration of ATP within 0.1 μM to 25 μM under optimal experimental conditions, and the detection limit is 33.85 nM. The biosensor exhibits a satisfactory specificity for ATP. Moreover, the experimental results indicate that the biosensor can be applied to determine the ATP in human serum. In conclusion, the screened aptamer and the biosensor have promising applications in the determination of the real energy charge level and ATP content in a complex biological system.

Abstract
The abnormal expression of miRNA-21 is often found in tumor specimens and cell lines, and thus, its specific detection is an urgent need for the diagnosis and effective therapy of cancers. In this contribution, we demonstrate a palindrome-based hybridization chain reaction (PHCR) upon the stimuli of a short oligonucleotide trigger to perform the autonomous assembly of cross-linked network structures (CNSs) for the amplification detection of miRNA-21 and sensitive fluorescence imaging of cancerous cells. The building blocks are only two palindromic hairpin-type DNA strands that are separately modified with different fluorophores (Cy3 and Cy5), which is easily combined with the catalytic hairpin assembly (CHA) technique that can further amplify the signal output. Utilizing the CHA-PHCR assay system, a small amount of miRNA-21 can activate many triggers via CHA and in turn induce the PHCR-based CNS assembly from more DNA building blocks, bringing Cy3 and Cy5 into close proximity to each other and generating ultrasensitive fluorescence resonance energy transfer signals. As a result, target miRNA can be quantitatively detected down to as low as 10 pM with high assay specificity. The coexisting nontarget miRNAs and other biomacromolecules do not interfere with signal transduction. The developed assay system is suitable for screening different expression levels of miRNA-21 in living cells by fluorescence imaging. The palindrome-based cross-linking assembly can enhance the intracellular stability of assembled nanostructures by at least fivefold and exhibit the good universality for the detection of other miRNAs. Moreover, cancerous cells can be distinguished from healthy cells, and the CHA-PHCR assay is in good accordance with the gold standard PCR method, indicating a promising platform for the diagnosis of human cancers and other genetic diseases.

Abstract
Herein, a metal-organic framework (UiO-66-NH2) with two functions (intrinsic fluorescence and fluorescence quenching ability) is designed to establish a ratiometric fluorescent platform for high-performance miRNA detection. The use of a fluorescent organic ligand endows the MOF material with a strong intrinsic fluorescence at 440 nm. In the presence of target miRNA, the fluorescence signal of the FAM is restored with the triple helix molecular beacons bind to the target. Using the IFAM/IMOF signal as the output, the prepared ratiometric probe was able to eliminate disturbance caused by the sensing environment. Under the optimal reaction conditions, including buffer pH of 7.4, temperature of 37 °C, and response time of 1 h, the best detection results can be obtained. The ratiometric fluorescence probe presented showed good sensitivity and selectivity for detecting miRNA-203 and the limit of detection was 400 pM with a wide linear range from 1 nM to 160 nM. In addition, this method was applied to diluted human serum and cell lysates, and good detection effect was realized.

Abstract
The DNA microarray has distinctive advantages of high-throughput and less complicated operations, but tends to have a relatively low sensitivity. Catalytic hairpin assembly (CHA) is one of the most promising enzyme-free, isothermal DNA circuit for high efficient signal amplification. Here, a microarray-based catalytic hairpin assembly (mi-CHA) biosensing method has been developed to detect various miRNAs in a single test simultaneously. The target miRNA can trigger conformational transformations of hairpin-structured DNA probes on the chip surface and lead to the specific signal amplification. A significant advantage of this approach is that each duplex produced by the solid-phase CHA will be immobilized on the certain location of the chip and release fluorescent signal via the universal domain, eliminating the requirement of different fluorophores. This method has manifested a high detection sensitivity of human cancer-associated miRNAs (miR-21 and miR-155) down to 1.33 fM and promised a high specificity to distinguish single-base mismatches. Furthermore, the practicability of this method was demonstrated by analyzing target miRNAs in human serum and cancer cells. The experimental results suggest that the proposed method has high-throughput analytical potential and could be applied to many other clinical diagnosis.

Abstract
Sensitive and specific detection of microRNAs (miRNAs) is of great significance for early cancer diagnosis. Here we report a simple and sensitive fluorescence signal amplification strategy that based on DSN/TdT recycling digestion for miRNA detection. DSN initiates DNA digestion on 3'-phosphate-primer/miRNA heteroduplex which causes miRNA recycle. The digested DNA strands with 3'-OH ends enable TdT to synthesize a polydeoxyguanylic tails on the 3'-end. The DNAs with polydeoxyguanylic tails are converted to double-stranded-DNA prior to initiation of DSN/TdT recycling digestion. With the cooperation of TdT and DSN, a new round of digestion and extension is triggered, leading to massive fluorophores separating and signal amplification. The amplification strategy produces large amounts of 3'-OH probes that can be used directly for dsDNA enrichment and DSN digestion. Moreover, both DSN digestion and TdT extension are sequence-independent reaction without the need of complex sequences design. In addition, this strategy is utilized to analyze miRNA samples from MCF-7 cell lysates and Cu (II) ion samples, indicating its potential application in actual sample analysis. The method shows a promising analytical platform for DNA nicking-related studies and tumor biomarkers measuring in clinical diagnostics.

Abstract
A novel reverse transcription-based loop-mediated isothermal amplification (LAMP) strategy for miRNA detection has been developed. This method consists of two stem-loop probes inspired by the dumbbell-shaped amplicons and inner primers used in conventional LAMP reactions. Termed "terminal hairpin formation and self-priming" (THSP), this reaction incorporates phosphorothioated (PS) modifications to achieve DNA folding and extension without primers. The final signal is monitored by a sequence-specific detection probe, which minimizes the background noise. We suggest that our rapid, facile, and reliable LAMP method will be a promising candidate for detecting miRNA in biomedical applications.

Abstract
A fluorescent aptasensor for Staphylococcus aureus (S. aureus) is designed, which takes advantage of strand displacement amplification (SDA) technology and unique self-assembled DNA hexagonal structure. In the presence of S. aureus, a partially complementary strand of S. aureus aptamer (cDNA) is competitively released from cDNA/aptamer duplex immobilized on magnetic beads due to the affinity of the aptamer for S. aureus. The addition of primer starts the SDA reaction. With the catalysis of Bsm DNA polymerase and Nb.bpu10I endonuclease, a large number of single-stranded DNA (ssDNA) is produced, which induces the opening of a hairpin probe and the subsequent self-assembly to form a hexagonal structure. The staining of the DNA hexagon with SYBR Green I excites the fluorescence signal, which is used for detection. The aptasensor exhibits a broad linear range from 7 to 7 × 107 CFU/mL, with a detection limit of 1.7 CFU/mL for S. aureus. The sensor shows negligible responses to other bacteria. Moreover, the aptasensor has been applied to detect S. aureus in milk samples, and the results demonstrate the general applicability of the sensor and its prospect in systematic detection of S. aureus in food safety control and medicine-related fields. Graphical abstract The presence of S. aureus can be converted to the formation of unique DNA hexagonal structure and subsequent fluorescent signal by the combination of SDA with self-assembly technology.

Abstract
The development of sensitive and convenient detection methods to monitor thrombin without the use of enzymes or complex nanomaterials is highly desirable for the diagnosis of cardiovascular diseases. In this article, tetraferrocene was first synthesized and then a sensitive and homogeneous electrochemical aptasensor was developed for thrombin detection based on host-guest recognition between tetraferrocene and β-cyclodextrin (β-CD). In the absence of thrombin, the double stem-loop of thrombin aptamer (TBA) prevented tetraferrocenes labeled at both ends from entering the cavity of β-CD deposited on gold electrode surface. After binding with thrombin, the stem-loop structure of TBA opened and transformed into special G-quarter structure, forcing tetraferrocene into the cavity of β-CD. As a result, thrombin allowed eight ferrocene molecules to reach the gold electrode surface, greatly amplifying the response signal. The obtained aptasensors showed dynamic detection range from 4 pM to 12.5 nM with detection limit around 1.2 pM. Overall, the results indicate that the proposed aptasensors are promising for future rapid clinical detection of thrombin and development of signal amplification strategies for detection of various proteins.

Abstract
Biological stimuli-responsive DNA hydrogels have attracted much attention in the field of medical engineering owing to their unique phase transitions from gel to sol through cleavage of DNA cross-linking points in response to specific biomolecular inputs. In this paper, a new class of biological stimuli-responsive DNA hydrogels with a dynamically programmed DNA system that relies on a DNA circuit system through cascading toehold-mediated DNA displacement reactions is constructed, allowing the catalytic cleavage of cross-linking points and main chains in response to an appropriate DNA input. The dynamically programmed DNA hydrogels exhibit a significant sharp phase transition from gel to sol in comparison to another DNA hydrogel showing noncatalytic cleavage of cross-linking points due to synchronization of the catalytic cleavage of cross-linking points and the main chains. Further, the sol-gel phase transitions of the DNA hydrogels in response to the DNA input are easily tunable by changing the cross-linking density. Additionally, with a structure-switching aptamer, DNA hydrogels encapsulating PEGylated gold nanoparticles can be used as enzyme-free signal amplifiers for the colorimetric detection of adenosine 5'-triphosphate (ATP); this detection system provides simplicity and higher sensitivity (limit of detection: 5.6 × 10-6 m at 30 min) compared to other DNA hydrogel-based ATP detection systems.

Abstract
Dynamic DNA nanotechnology, a subfield of DNA nanotechnology, is concerned with the study and application of nucleic acid strand-displacement reactions. Strand-displacement reactions generally proceed by three-way or four-way branch migration and initially were investigated for their relevance to genetic recombination. Through the use of toeholds, which are single-stranded segments of DNA to which an invader strand can bind to initiate branch migration, the rate with which strand displacement reactions proceed can be varied by more than 6 orders of magnitude. In addition, the use of toeholds enables the construction of enzyme-free DNA reaction networks exhibiting complex dynamical behavior. A demonstration of this was provided in the year 2000, in which strand displacement reactions were employed to drive a DNA-based nanomachine (Yurke, B.; et al. Nature 2000, 406, 605-608). Since then, toehold-mediated strand displacement reactions have been used with ever increasing sophistication and the field of dynamic DNA nanotechnology has grown exponentially. Besides molecular machines, the field has produced enzyme-free catalytic systems, all DNA chemical oscillators and the most complex molecular computers yet devised. Enzyme-free catalytic systems can function as chemical amplifiers and as such have received considerable attention for sensing and detection applications in chemistry and medical diagnostics. Strand-displacement reactions have been combined with other enzymatically driven processes and have also been employed within living cells (Groves, B.; et al. Nat. Nanotechnol. 2015, 11, 287-294). Strand-displacement principles have also been applied in synthetic biology to enable artificial gene regulation and computation in bacteria. Given the enormous progress of dynamic DNA nanotechnology over the past years, the field now seems poised for practical application.

Abstract
High-throughput profiling/sensing of nucleic acids has recently emerged as a highly promising strategy for the early diagnosis and improved prognosis of a broad range of pathologies, most notably cancer. Among the potential biomarker candidates, microRNAs (miRNAs), a class of non-coding RNAs of 19-25 nucleotides in length, are of particular interest due to their role in the post-transcriptional regulation of gene expression. Developing miRNA sensing technologies that are quantitative, ultrasensitive and highly specific has proven very challenging because of their small size, low natural abundance and the high degree of sequence similarity among family members. When compared to optical based methods, electrochemical sensors offer many advantages in terms of sensitivity and scalability. This non-comprehensive review aims to break-down and highlight some of the most promising strategies for electrochemical sensing of microRNA biomarkers.

Abstract
Because circulating microRNAs (miRNAs) have been recognized as a new class of blood-based biomarkers for various diseases, a significant challenge has been the development of point-of-care testing (POCT) systems based on detection of circulating miRNAs directly from serum. A promising approach to POCT systems is considered to be the development of enzyme-free and isothermal detection systems. Here, two types of DNA circuit system based on proportional and exponential amplification strategies were constructed using double-stranded DNA-modified magnetic beads (dsDNA-MBs) and their performances for detection of miRNA were studied comparatively. Both proportional and exponential amplification DNA circuit systems enabled the detection of target miRNA (miR-141) at room temperature without the need for additional enzymes because miR-141 acted as a catalyst for successive toehold-mediated DNA displacement reactions. A significant increase in the noise fluorescence signal was observed for the exponential amplification DNA circuit system because of the leakage (undesired DNA displacement reaction) revealed by the kinetic study on each DNA displacement reaction. Nevertheless, the exponential amplification DNA circuit system showed a lower limit of detection (LOD: 46 pM) and shorter assay time (15 min) compared to those of the proportional amplification DNA circuit system (LOD: 103 pM at 180 min). It is most likely that the exponential amplification DNA circuit system enabled amplification of both the signals and target miR-141, whereas the proportional amplification DNA circuit system enabled amplification of the signals alone. In addition, the exponential amplification DNA circuit system was able to discriminate between mismatched base sequences in miR-200 family members and specifically detect miR-141 even in the presence of serum. These findings are important for the rational design for POCT systems.

Abstract
The monitoring of intracellular microRNAs plays important roles in elucidating the biological function and biogenesis of miRNAs in living cells. However, because of their sequence similarity, low abundance, and small size, it is a great challenge to detect intracellular miRNAs, especially for those with much lower expression levels. To address this issue, we have developed an in cell signal amplification approach for monitoring down-regulated miRNAs in living cells based on biodegradable MnO2 nanosheet-mediated and target-triggered assembly of hairpins. The MnO2 nanosheets can adsorb and exhibit an excellent quenching effect to the dye labeled hairpin probes. Besides, due to their biodegradability, the MnO2 nanosheets feature highly reduced cytotoxicity to the target cells. Upon entering cells, the surface-adsorbed FAM- and Tamra (TMR)-conjugated hairpins can be released due to the displacement reactions by other proteins or nucleic acids and the degradation of the MnO2 nanosheets by cellular GSH. Subsequently, the down-regulated target miRNA-21 triggers cascaded assembly of the two hairpins into long dsDNA polymers, which brings the fluorescence resonance energy transfer (FRET) pair, FAM (donor), and TMR (acceptor) into close proximity to generate significantly enhanced FRET signals for detecting trace miRNA-21 in living cells. By carefully tailoring the sequences of the hairpins, the developed method can offer new opportunities for monitoring various trace intracellular miRNA targets with low expression levels in living cells.

Abstract
Thrombin plays important roles for the diagnosis of neurodegenerative and cardiovascular diseases. By integrating proximity binding-induced strand displacement and metal ion-dependent DNAzyme recycling amplification, we demonstrate here the development of a simple and sensitive strategy for the detection of thrombin in human serums. The binding of the two distinct aptamers to the thrombin targets increases the local concentration of the aptamers and facilitates the release of the enzymatic sequences through proximity binding-induced strand displacement. The liberated enzymatic sequences further hybridize with the G-quadruplex containing and hairpin-structured substrate sequences on the sensor electrode to form the metal-ion dependent DNAzymes. Subsequently, the metal ions catalyze the cleavage of the substrate sequences to unlock the G-quadruplex forming sequences and to release the enzymatic sequences to trigger another cleavage cycle. Such metal ion-dependent DNAzyme recycling amplification leads to the formation of many active G-quadruplex forming sequences, which associate with hemin to form G-quadruplex/hemin complexes on the electrode surface. Direct electron transfer of hemin to the electrode during the potential scan can thus generate significantly amplified current for sensitive detection of thrombin at the low picomolar level. The work demonstrated here can thus offer new opportunities for the development of convenient signal amplification strategies for detecting various protein targets.
