Supramolecular DNA-based catalysis in organic solvents. iScience 2024; 27:109689. [PMID: 38706840 PMCID: PMC11067378 DOI: 10.1016/j.isci.2024.109689] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Revised: 10/04/2023] [Accepted: 04/05/2024] [Indexed: 05/07/2024] Open
Abstract
The distinct folding accompanied by its polymorphic character renders DNA G-quadruplexes promising biomolecular building blocks to construct novel DNA-based and supramolecular assemblies. However, the highly polar nature of DNA limits the use of G-quadruplexes to water as a solvent. In addition, the archetypical G-quadruplex fold needs to be stabilized by metal-cations, which is usually a potassium ion. Here, we show that a noncovalent PEGylation process enabled by electrostatic interactions allows the first metal-free G-quadruplexes in organic solvents. Strikingly, incorporation of an iron-containing porphyrin renders the self-assembled metal-free G-quadruplex catalytically active in organic solvents. Hence, these "supraG4zymes" enable DNA-based catalysis in organic media. The results will allow the broad utilization of DNA G-quadruplexes in nonaqueous environments.

Abstract
With the emergence of DNA nanotechnology in the 1980s, self-assembled DNA nanostructures have attracted considerable attention worldwide due to their inherent biocompatibility, unsurpassed programmability, and versatile functions. Especially promising nanostructures are tetrahedral framework nucleic acids (tFNAs), first proposed by Turberfield with the use of a one-step annealing approach. Benefiting from their various merits, such as simple synthesis, high reproducibility, structural stability, cellular internalization, tissue permeability, and editable functionality, tFNAs have been widely applied in the biomedical field as three-dimensional DNA nanomaterials. Surprisingly, tFNAs exhibit positive effects on cellular biological behaviors and tissue regeneration, which may be used to treat inflammatory and degenerative diseases. According to their intended application and carrying capacity, tFNAs could carry functional nucleic acids or therapeutic molecules through extended sequences, sticky-end hybridization, intercalation, and encapsulation based on the Watson and Crick principle. Additionally, dynamic tFNAs also have potential applications in controlled and targeted therapies. This review summarized the latest progress in pure/modified/dynamic tFNAs and demonstrated their regenerative medicine applications. These applications include promoting the regeneration of the bone, cartilage, nerve, skin, vasculature, or muscle and treating diseases such as bone defects, neurological disorders, joint-related inflammatory diseases, periodontitis, and immune diseases.

Abstract
G-Quadruplexes attract growing interest as functional constituents in biology, chemistry, nanotechnology, and material science. In particular, the reversible dynamic reconfiguration of G-quadruplexes provides versatile means to switch DNA nanostructures, reversibly control catalytic functions of DNA assemblies, and switch material properties and functions. The present review article discusses the switchable dynamic reconfiguration of G-quadruplexes as central functional and structural motifs that enable diverse applications in DNA nanotechnology and material science. The dynamic reconfiguration of G-quadruplexes has a major impact on the development of DNA switches and DNA machines. The integration of G-quadruplexes with enzymes yields supramolecular assemblies exhibiting switchable catalytic functions guided by dynamic G-quadruplex topologies. In addition, G-quadruplexes act as important building blocks to operate constitutional dynamic networks and transient dissipative networks mimicking complex biological dynamic circuitries. Furthermore, the integration of G-quadruplexes with DNA nanostructures, such as origami tiles, introduces dynamic and mechanical features into these static frameworks. Beyond the dynamic operation of G-quadruplex structures in solution, the assembly of G-quadruplexes on bulk surfaces such as electrodes or nanoparticles provides versatile means to engineer diverse electrochemical and photoelectrochemical devices and to switch the dynamic aggregation/deaggregation of nanoparticles, leading to nanoparticle assemblies that reveal switchable optical properties. Finally, the functionalization of hydrogels, hydrogel microcapsules, or nanoparticle carriers, such as SiO2 nanoparticles or metal-organic framework nanoparticles, yields stimuli-responsive materials exhibiting shape-memory, self-healing, and controlled drug release properties. Indeed, G-quadruplex-modified nanomaterials find growing interest in the area of nanomedicine. Beyond the impressive G-quadruplex-based scientific advances achieved to date, exciting future developments are still anticipated. The review addresses these goals by identifying the potential opportunities and challenges ahead of the field in the coming years.

Abstract
In nature, intact apoptotic cells release ATP as a signaling molecule to trigger prompt phagocytic clearance, even at the earliest stage of apoptosis. Inspired by this, here we introduce a straightforward strategy for real-time monitoring ATP exocytosis and drug-stimulated apoptosis in the cancer cell surroundings. Triplex-boosted G-quadruplexes (tb-G4s) responding to cell environmental factors (H+ and K+ ) are engineered to construct a DNA logic-gated nanoplatform for proximity ATP aptasensing on the cell surface. It enables the real-time monitoring of cell apoptosis by capturing released endogenous ATP during chemotherapy drug stimulation, providing a sensitive approach for dynamically evaluating drug-induced apoptosis and therapeutic efficacy.

Abstract
Stimuli-responsive metal-organic framework nanoparticles, NMOFs, provide a versatile platform for the controlled release of drugs and biomedical applications. The porous structure of NMOFs, their biocompatibility, low toxicity, and efficient permeability turn the NMOFs into ideal carriers for therapeutic applications. Two general methods to gate the drug-loaded NMOFs and to release the loads were developed: by one method, the loaded NMOFs are coated or surface-modified with stimuli-responsive gates being unlocked in the presence of appropriate chemical (e.g., ions or reducing agents), physical (e.g., light or heat), or biomarker (e.g., miRNA or ATP) triggers. By a second approach, the drug-loaded NMOFs include encoded structural information or co-added agents to induce the structural distortion or stimulate the degradation of the NMOFs. Different chemical triggers such as pH changes, ions, ATP, or redox agents, and physical stimuli such as light or heat are applied to degrade the NMOFs, resulting in the release of the loads. In addition, enzymes, DNAzymes, and disease-specific biomarkers are used to unlock the gated NMOFs. The triggered release of drugs for cancer therapy, anti-blood clotting, and the design of autonomous insulin-delivery systems ("artificial pancreas") are discussed. Specifically, multi-drug carrier systems and functional NMOFs exhibiting dual and cooperative therapeutic functions are introduced. The future perspectives and applications of stimuli-responsive particles are addressed.

Abstract
The reversible and switchable triggered reconfiguration of tetrahedra nanostructures from monomer tetrahedra structures into dimer or trimer structures is introduced. The triggered bridging of monomer tetrahedra by K+ -ion-stabilized G-quadruplexes or T-A•T triplexes leads to dimer or trimer tetrahedra structures that are separated by crown ether or basic pH conditions, respectively. The signal-triggered dimerization/trimerization of DNA tetrahedra structures is used to develop multiplexed miRNA-sensing platforms, and the tetrahedra mixture is used for intracellular sensing and imaging of miRNAs.

Abstract
Two novel electrochemiluminescence (ECL) deoxyribosensors are designed for assay of early lung cancer biomarker (NAP2) using the DNA three-way junction (DNA-TWJ) inserted NAP2 binding aptamer between two double-helical stems and labeled with ruthenium (II) complex (Ru) (NBAT-Ru) taken as molecular recognition element. The signal-off ECL deoxyribosensor was fabricated by covalently coupling the 5'-NH2-(CH2)6-NBAT-Ru to glassy carbon electrode surface modified with 4-aminobenzoic acid (4-ABA). After combining NAP2 and NBAT-Ru, the changed conformation of NBAT-Ru altered the distance between Ru complex and electrode, resulting in a low ECL signal. The signal-on deoxyribosensor was fabricated by self-assembling the 5'-SH-(CH2)6-NBAT-Ru onto the Au electrode. The introduction of NAP2 triggered the conformational change in the aptamer domain, which induces the interhelical stacking of the two double-helical stems of NBAT-Ru. This stacking constitutes "electrical contact," which promotes transmission of electron-holes through the stems of NBAT-Ru, and produces high ECL intensity. Both deoxyribosensors show high sensitivity and selectivity. The biosensors have been successfully applied to clinical plasma detection. The approaches we describe represent unique principles based on DNA-TWJ inserted target special binding domain as molecular recognition element and different immobilization types for the fabrication of biosensors, which are greatly promising for the detection of protein, metal ions, bacteria, and cells.

Abstract
Despite numerous biosensors currently available, the routine biomarker detection still largely relies on traditional ELISA and Western blot. Those standard techniques are labor intensive and time-consuming. Herein we introduce a fast affinity induced reaction sensor (FAIRS) that overcomes a few limitations of traditional and emerging biosensors. FAIRS is a general, one-step method and is naturally specific in detection. FAIRS probes are composed of a sandwich ELISA antibody pair that is conjugated with two fluorogenic click chemicals. This technology leverages significant differences of antibody affinity and chemical reaction rate, which are characterized to guide probe design. The stability, sensitivity, detection range, and response time are fully characterized. Application to IL-6 detection using blood serum and cell culture medium demonstrates that FAIRS can quantify IL-6 with high sensitivity in one step. With the unique features, FAIRS probes may find broad applications in medical sciences and clinical diagnostics, where quick detection of biomarkers is demanded.

Abstract
The relatively low stability and polymorphism of bimolecular G-quadruplexes (bi-G4s) are big difficulties that are faced in employing them to guide DNA assembly, as they are usually subject to a transformation into more stable tetramolecular or G-wire structures favored by K+ or Mg2+. Although bi-G4s benefit by additional duplex handles, a challenge remains in tailoring their intrinsic properties to resolve the above difficulties. Toward this challenge, here we engineer several ultrastable bi-G4s via replacing their nucleotide loops with special mini-hairpins, which consist of a GAA loop and a short GC-paired stem. Such a structural alteration favors the formation of G:C:G:C tetrads in the head-to-head folding topologies of bi-G4s and improves their thermal stability, with an increase in the melting temperature by up to 25 °C. It dramatically reduces their structural conversion into G-wires, verified by atomic force microscopy. These features enable the utilization of two well-chosen bi-G4s to shape a DNA nanotriangle into the desired framework nucleic acid (FNA) architectures such as "bowknot" and "butterfly" that are reversibly switched by the bi-G4s. On this basis, we further build a reconfigurable DNAzyme device to mimic the activation of human telomerase that is modulated by the G4 dimerization. Our designed ultrastable bi-G4s will offer a promising tool for dynamically manipulating intracellular DNA nanoassemblies with endogenous K+ and exploring the relationship between dimerization and function in some physiological processes.

Abstract
Despite 25 years' effort, serious questions remain regarding the mechanism(s) underlying electron transfer through (or from) electrode-bound double-stranded DNA. In part this is because a control experiment regarding the putatively critical role of guanine bases in the most widely proposed transport mechanism (hopping from guanine to guanine through the π-stack) appears to be lacking from the prior literature. In response, we have employed chronoamperometry, which allows for high-precision determination of electron transfer rates, to characterize transfer to a redox reporter appended onto electrode-bound DNA duplexes. Specifically, we have measured the effects of guanines and base mismatches on the electron transfer rate associated with such constructs. Upon doing so, we find that, counter to prior reports, the transfer rate is, to within relatively tight experimental confidence intervals, unaffected by either. Parallel studies of the dependence of the electron transfer rate on the length of the DNA suggest that transfer from this system obeys a "collision" mechanism in which the redox reporter physically contacts the electrode surface prior to the exchange of electrons.

Abstract
Current strategies for high-performance immunoassay generally require a sandwich structure for signal amplification. This strategy is limited to multivalent antigens and complicates the detection scheme. Herein we demonstrate a class of simple one-step ultrasensitive immunoassay with the adoption of double-stranded DNA (dsDNA) as "conductive spring" to bridge the electrode and redox-reporter/antibody-receptor comodified gold nanoparticles (AbFc@AuNPs). Upon biorecognition between antigen and antibody, the charge of the AuNPs changes, enhancing the electrostatic interaction between the AuNPs and Au electrode surface, and condensing the dsDNA chain. For the first time, the sensitive response of the electrochemical redox current to the DNA chain length is utilized to achieve an ultrahigh sensitivity down to fM level. Only the primary antibody needed in the recognition interface ensures the one-step immunoreaction works well with monovalent antigens, which ensure this method as a promising general alternative means for fast, high-throughput or point-of-care clinical applications even for very challenging clinically relevant samples.

Abstract
Electrochemical, aptamer-based (E-AB) sensors support the continuous, real-time measurement of specific small molecules directly in situ in the living body over the course of many hours. They achieve this by employing binding-induced conformational changes to alter electron transfer from a redox-reporter-modified, electrode-attached aptamer. Previously we have used voltammetry (cyclic, alternating current, and square wave) to monitor this binding-induced change in transfer kinetics indirectly. Here, however, we demonstrate the potential advantages of employing chronoamperometry to measure the change in kinetics directly. In this approach target concentration is reported via changes in the lifetime of the exponential current decay seen when the sensor is subjected to a potential step. Because the lifetime of this decay is independent of its amplitude (e.g., insensitive to variations in the number of aptamer probes on the electrode), chronoamperometrically interrogated E-AB sensors are calibration-free and resistant to drift. Chronoamperometric measurements can also be performed in a few hundred milliseconds, improving the previous few-second time resolution of E-AB sensing by an order of magnitude. To illustrate the potential value of the approach we demonstrate here the calibration-free measurement of the drug tobramycin in situ in the living body with 300 ms time resolution and unprecedented, few-percent precision in the determination of its pharmacokinetic phases.

Abstract
The electrochemical, aptamer-based (E-AB) sensor platform provides a modular approach to the continuous, real-time measurement of specific molecular targets (irrespective of their chemical reactivity) in situ in the living body. To achieve this, however, requires the fabrication of sensors small enough to insert into a vein, which, for the rat animal model we employ, entails devices less than 200 μm in diameter. The limited surface area of these small devices leads, in turn, to low faradaic currents and poor signal-to-noise ratios when deployed in the complex, fluctuating environments found in vivo. In response we have developed an electrochemical roughening approach that enhances the signaling of small electrochemical sensors by increasing the microscopic surface area of gold electrodes, allowing in this case more redox-reporter-modified aptamers to be packed onto the surface, thus producing significantly improved signal-to-noise ratios. Unlike previous approaches to achieving microscopically rough gold surfaces, our method employs chronoamperometric pulsing in a 5 min etching process easily compatible with batch manufacturing. Using these high surface area electrodes, we demonstrate the ability of E-AB sensors to measure complete drug pharmacokinetic profiles in live rats with precision of better than 10% in the determination of drug disposition parameters.

Abstract
The need to calibrate to correct for sensor-to-sensor fabrication variation and sensor drift has proven a significant hurdle in the widespread use of biosensors. To maintain clinically relevant (±20% for this application) accuracy, for example, commercial continuous glucose monitors require recalibration several times a day, decreasing convenience and increasing the chance of user errors. Here, however, we demonstrate a "dual-frequency" approach for achieving the calibration-free operation of electrochemical biosensors that generate an output by using square-wave voltammetry to monitor binding-induced changes in electron transfer kinetics. Specifically, we use the square-wave frequency dependence of their response to produce a ratiometric signal, the ratio of peak currents collected at responsive and non- (or low) responsive square-wave frequencies, which is largely insensitive to drift and sensor-to-sensor fabrication variations. Using electrochemical aptamer-based (E-AB) biosensors as our test bed, we demonstrate the accurate and precise operation of sensors against multiple drugs, achieving accuracy in the measurement of their targets of within better than 20% across dynamic ranges of up to 2 orders of magnitude without the need to calibrate each individual sensor.

Abstract
A MYC sequence forming an intramolecular G-quadruplex with a parallel topology was modified by the incorporation of 8-bromoguanosine (BrG) analogues in one of its outer G-tetrads. The propensity of the BrG analogues to adopt a syn glycosidic torsion angle results in an exceptional monomolecular quadruplex conformation featuring a complete flip of one tetrad while keeping a parallel orientation of all G-tracts as shown by circular dichroism and nuclear magnetic resonance spectroscopic studies. When substituting three of the four G-tetrad residues with BrG analogues, two coexisting quadruplex conformational isomers with an all-syn and all-anti outer G-quartet are approximately equally populated in solution. A dynamic interconversion of the two quadruplexes with an exchange rate (kex) of 0.2 s-1 is demonstrated through the observation of exchange crosspeaks in rotating frame Overhauser effect spectroscopy and nuclear Overhauser effect spectroscopy experiments at 50 °C. The kinetic properties suggest disruption of the corresponding outer G-tetrad but not of the whole quadruplex core during the tetrad flip. Conformational syn-anti isomers with homopolar and heteropolar stacking interactions are nearly isoenergetic with a transition enthalpy of 18.2 kJ/mol in favor of the all-syn isomer.

Abstract
Reversible pH-responsive dimer or trimer origami structures are assembled by bridging origami frames with pH-responsive units. The cyclic pH-stimulated separation and reassembly of dimer origami structures is demonstrated using i-motif or Hoogsteen-type (C-G·C+ or T-A·T) interactions. The duplex-bridged dimer T1-T2 is separated by the pH-induced formation of an i-motif structure (pH = 4.5), and the dimer is reassembled at pH = 7.0. The duplex-bridged dimer, T3-T4, is separated at pH = 4.5 through the formation of C-G·C+ triplex structures and is reassembled to the dimer at pH = 7.0. Similarly, the T-A·T triplex-bridged dimer, T5-T6, is separated at pH = 9.5 and is reassembled at neutral pH. Finally, a trimer, T3-T7-T6, that includes C-G·C+ and T-A·T pH-responsive bridges reveals pH-programmed cleavage to selectively yield the dimers T3-T7 or T7-T6, which reassemble to the trimer at pH = 7.0. A linear three-frame origami structure bridged by duplexes including caged i-motif units undergoes pH-stimulated isomerization to a bent structure (pH = 4.5) through the formation of i-motif complex and bridging T-A·T triplex units.

Abstract
In this paper, we report a novel surface-tethered DNA nanodevice that may present three states and undergo conformational changes under the operation of pH. Besides, convenient regulation on the electrode surface renders the construction and operation of this DNA nanodevice restorable. To make full use of this DNA nanodevice, ferrocene (Fc) has been further employed for the fabrication of the molecular device. On one hand, the state switches of the DNA nanodevice can be characterized conveniently and reliably by the obtained electrochemical signals from Fc. On the other hand, β-cyclodextrin-ferrocene (β-CD-Fc) host-guest system can be introduced by Fc, which functionalizes this molecular device. Based on different electrochemical behaviors of β-CD under different states, this DNA nanodevice can actualize directional loading, transporting and unloading of β-CD in nanoscale. Therefore, this DNA nanodevice bares promising applications in controllable molecular transport and release, which are of great value to molecular device design.

Abstract
The folding of single-stranded telomeric DNA into guanine (G) quadruplexes is a conformational change that plays a major role in sensing and drug targeting. The telomeric DNA can be placed on DNA origami nanostructures to make the folding process extremely selective for K(+) ions even in the presence of high Na(+) concentrations. Here, we demonstrate that the K(+)-selective G-quadruplex formation is reversible when using a cryptand to remove K(+) from the G-quadruplex. We present a full characterization of the reversible switching between single-stranded telomeric DNA and G-quadruplex structures using Förster resonance energy transfer (FRET) between the dyes fluorescein (FAM) and cyanine3 (Cy3). When attached to the DNA origami platform, the G-quadruplex switch can be incorporated into more complex photonic networks, which is demonstrated for a three-color and a four-color FRET cascade from FAM over Cy3 and Cy5 to IRDye700 with G-quadruplex-Cy3 acting as a switchable transmitter.

Abstract
Acrylamide-acrylamide nucleic acids are cross-linked by two cooperative functional motives to form shaped acrylamide-DNA hydrogels. One of the cross-linking motives responds to an external trigger, leading to the dissociation of one of the stimuli-responsive bridges, and to the transition of the stiff shaped hydrogels into soft shapeless states, where the residual bridging units, due to the chains entanglement, provide an intrinsic memory for the reshaping of the hydrogels. Subjecting the shapeless states to counter stimuli restores the dissociated bridges, and regenerates the original shape of the hydrogels. By the cyclic dissociation and reassembly of the stimuli-responsive bridges, the reversible switchable transitions of the hydrogels between stiff shaped hydrogel structures and soft shapeless states are demonstrated. Shaped hydrogels bridged by K(+)-stabilized G-quadruplexes/duplex units, by i-motif/duplex units, or by two different duplex bridges are described. The cyclic transitions of the hydrogels between shaped and shapeless states are stimulated, in the presence of appropriate triggers and counter triggers (K(+) ion/crown ether; pH = 5.0/8.0; fuel/antifuel strands). The shape-memory hydrogels are integrated into shaped two-hydrogel or three-hydrogel hybrid structures. The cyclic programmed transitions of selective domains of the hybrid structures between shaped hydrogel and shapeless states are demonstrated. The possible applications of the shape-memory hydrogels for sensing, inscription of information, and controlled release of loads are discussed.

Abstract
G-quadruplexes are four-stranded nucleic acid structures that are built from consecutively stacked guanine tetrad (G-tetrad) assemblies. The simultaneous incorporation of two guanine base lesions, xanthine (X) and 8-oxoguanine (O), within a single G-tetrad of a G-quadruplex was recently shown to lead to the formation of a stable G⋅G⋅X⋅O tetrad. Herein, a judicious introduction of X and O into a human telomeric G-quadruplex-forming sequence is shown to reverse the hydrogen-bond polarity of the modified G-tetrad while preserving the original folding topology. The control exerted over G-tetrad polarity by joint X⋅O modification will be valuable for the design and programming of G-quadruplex structures and their properties.

Abstract
We demonstrate the single-molecule imaging of the catalytic reaction of a Zn(2+)-dependent DNAzyme in a DNA origami nanostructure. The single-molecule catalytic activity of the DNAzyme was examined in the designed nanostructure, a DNA frame. The DNAzyme and a substrate strand attached to two supported dsDNA molecules were assembled in the DNA frame in two different configurations. The reaction was monitored by observing the configurational changes of the incorporated DNA strands in the DNA frame. This configurational changes were clearly observed in accordance with the progress of the reaction. The separation processes of the dsDNA molecules, as induced by the cleavage by the DNAzyme, were directly visualized by high-speed atomic force microscopy (AFM). This nanostructure-based AFM imaging technique is suitable for the monitoring of various chemical and biochemical catalytic reactions at the single-molecule level.

Abstract
Two-ring interlocked DNA catenanes are synthesized and characterized. The supramolecular catenanes show switchable cyclic catalytic properties. In one system, the catenane structure is switched between a hemin/G-quadruplex catalytic structure and a catalytically inactive state. In the second catenane structure the catenane is switched between a catalytically active Mg(2+)-dependent DNAzyme-containing catenane and an inactive catenane state. In the third system, the interlocked catenane structure is switched between two distinct catalytic structures that include the Mg(2+)- and the Zn(2+)-dependent DNAzymes.

Abstract
The base sequence of nucleic acid encodes structural and functional properties into the biopolymer. Structural information includes the formation of duplexes, G-quadruplexes, i-motif, and cooperatively stabilized assemblies. Functional information encoded in the base sequence involves the strand-displacement process, the recognition properties by aptamers, and the catalytic functions of DNAzymes. This Review addresses the implementation of the information encoded in nucleic acids to develop DNA switches. A DNA switch is a supramolecular nucleic acid assembly that undergoes cyclic, switchable, transitions between two distinct states in the presence of appropriate triggers and counter triggers, such as pH value, metal ions/ligands, photonic and electrical stimuli. Applications of switchable DNA systems to tailor switchable DNA hydrogels, for the controlled drug-release and for the activation of switchable enzyme cascades, are described, and future perspectives of the systems are addressed.

Abstract
We report here the formation of stable DNA quadruplex-duplex hybrid complexes harboring multiple duplex stems within the same loop of a quadruplex structure. The folding topology of a two-stem quadruplex-duplex hybrid construct was validated using nuclear magnetic resonance (NMR) spectroscopy. This multi-stem incorporation principle is applicable at different loop positions of the same quadruplex construct and could be extended to three or more duplex stems, giving rise to a diverse range of possible structures. These multi-stem complexes offer new design principles for the assembly of DNA architectures. The potential existence of such complex motifs in genomic sequences could have biological implications and would represent novel targets for drug development.

Abstract
The hemin/G-quadruplex-catalyzed generation of chemiluminescence through the oxidation of luminol by H2O2 stimulates the chemiluminescence resonance energy transfer (CRET) to CdSe/ZnS quantum dots (QDs), resulting in the luminescence of the QDs. By the cyclic K(+)-ion-induced formation of the hemin/G-quadruplex linked to the QDs, and the separation of the G-quadruplex in the presence of 18-crown-6-ether, the ON-OFF switchable CRET-induced luminescence of the QDs is demonstrated. QDs were modified with nucleic acids consisting of the G-quadruplex subunits sequences and of programmed domains that can be cross-linked through hybridization, using an auxiliary scaffold. In the presence of K(+)-ions, the QDs aggregate through the cooperative stabilization of K(+)-ion-stabilized G-quadruplex bridges and duplex domains between the auxiliary scaffold and the nucleic acids associated with the QDs. In the presence of 18-crown-6-ether, the K(+)-ions are eliminated from the G-quadruplex units, leading to the separation of the aggregated QDs. By the cyclic treatment of the QDs with K(+)-ions/18-crown-6-ether, the reversible aggregation/deaggregation of the QDs is demonstrated. The incorporation of hemin into the K(+)-ion-stabilized G-quadruplex leads to the ON-OFF switchable CRET-stimulated luminescence of the QDs. By the mixing of appropriately modified two-sized QDs, emitting at 540 and 610 nm, the dual ON-OFF activation of the luminescence of the QDs is demonstrated.

Abstract
Recent developments in nanoscience research have demonstrated that DNA switches (rationally designed DNA nanostructures) constitute a class of versatile building blocks for the fabrication and assembly of electronic devices and sensors at the nanoscale. Functional DNA sequences and structures such as aptamers, DNAzymes, G-quadruplexes, and i-motifs can be readily prepared in vitro, and subsequently adapted to an electrochemical platform by coupling with redox reporters. The conformational or conduction switching of such electrode-bound DNA modules in response to an external stimulus can then be monitored by conventional voltammetric measurements. In this review, we describe how we are able to design and examine functional DNA switches, particularly those systems that utilize electrochemical signaling. We also discuss different available options for labeling functional DNA with redox reporters, and comment on the function-oriented signaling pathways.

Abstract
Contractile duplexes are DNA double helices that incorporate two strategically placed patches of guanine-guanine (G·G) base mismatches. Such duplexes are cation-driven mechatronic devices, able to toggle between states with distinct mechanical and charge conduction properties. In aqueous lithium chloride solution contractile duplexes have an extended (E) and poorly conductive conformation; however, potassium ions drive them to a relatively conductive and structurally contracted (C) conformation, via intramolecular G-quadruplex formation. Here, we report that even in the absence of K(+) ions, a known G-quadruplex binding ligand, Pt-PIP [phenylphenanthroimidazole ethylenediamine platinum(II)] efficiently promotes the E→C transition, while a poor binder, Pt-bpy [bipyridine ethylenediamine platinum(II)], does not promote this transition. An examination of E→C transitions within two different designs for DNA contractile helices found an unexpected complexity: the formation of distinct C states, both electrically conductive, but possessing dissimilar DNA topologies. Ligand-driven DNA mechatronic devices such as these may constitute prototypes for electronic biosensors that identify G-quadruplex binding ligands.

Abstract
DNA three-way junctions (DNA TWJs) are important building blocks to construct DNA architectures and dynamic assemblies. We describe here a binding-induced DNA TWJ strategy that is able to convert protein bindings to the formation of DNA TWJ. The binding-induced DNA TWJ makes use of two DNA motifs each conjugated to an affinity ligand. The binding of two affinity ligands to the target molecule triggers assembly of the DNA motifs and initiates the subsequent DNA strand displacement, resulting in a binding-induced TWJ. Real-time fluorescence monitoring of the binding-induced TWJ enables detection of the specific protein targets. A detection limit of 2.8 ng/mL was achieved for prostate-specific antigen. The binding-induced TWJ approach compares favorably with the toehold-mediated DNA strand-displacement, the associative (combinative) toehold-mediated DNA strand-displacement, and the binding-induced DNA strand-displacement. Importantly, the binding-induced TWJ broadens the scope of dynamic DNA assemblies and provides a new strategy to design protein-responsive DNA devices and assemblies.

Abstract
DNA is a powerful biomaterial for creating rationally designed and functionally enhanced nanostructures. DNA nanoarchitectures positioned at substrate interfaces can offer unique advantages leading to improved surface properties relevant to biosensing, nanotechnology, materials science, and cell biology. This Perspective highlights the benefits and challenges of using assembled DNA as a nanoscale building block for interfacial layers and surveys their applications in three areas: homogeneous dense surface coatings, bottom-up nanopatterning, and 3D nanoparticle lattices. Possible future research developments are discussed at the end of the Perspective.
