Abstract
Flowing fluid past chiral objects has been used for centuries to power rotary motion in man-made machines. By contrast, rotary motion in nanoscale biological or chemical systems is produced by biasing Brownian motion through cyclic chemical reactions. Here we show that a chiral biological molecule, a DNA or RNA duplex rotates unidirectionally at billions of revolutions per minute when an electric field is applied along the duplex, with the rotation direction being determined by the chirality of the duplex. The rotation is found to be powered by the drag force of the electro-osmotic flow, realizing the operating principle of a macroscopic turbine at the nanoscale. The resulting torques are sufficient to power rotation of nanoscale beads and rods, offering an engineering principle for constructing nanoscale systems powered by electric field.

Abstract
Nucleic acid networks conjugated to native enzymes and supramolecular DNA nanostructures modified with enzymes or DNAzymes act as functional reaction modules for guiding dynamic catalytic transformations. These systems are exemplified with the assembly of constitutional dynamic networks (CDNs) composed of nucleic acid-functionalized enzymes, as constituents, undergoing triggered structural reconfiguration, leading to dynamically switched biocatalytic cascades. By coupling two nucleic acid/enzyme networks, the intercommunicated feedback-driven dynamic biocatalytic operation of the system is demonstrated. In addition, the tailoring of a nucleic acid/enzyme reaction network driving a dissipative, transient, biocatalytic cascade is introduced as a model system for out-of-equilibrium dynamically modulated biocatalytic transformation in nature. Also, supramolecular nucleic acid machines or DNA nanostructures, modified with DNAzyme or enzyme constituents, act as functional reaction modules driving temporal dynamic catalysis. The design of dynamic supramolecular machines is exemplified with the introduction of an interlocked two-ring catenane device that is dynamically reversibly switched between two states operating two different DNAzymes, and with the tailoring of a DNA-tweezers device functionalized with enzyme/DNAzyme constituents that guides the dynamic ON/OFF operation of a biocatalytic cascade by opening and closing the molecular device. In addition, DNA origami nanostructures provide functional scaffolds for the programmed positioning of enzymes or DNAzyme for the switchable operation of catalytic transformations. This is introduced by the tailored functionalization of the edges of origami tiles with nucleic acids guiding the switchable formation of DNAzyme catalysts through the dimerization/separation of the tiles. In addition, the programmed deposition of two-enzyme/cofactor constituents on the origami raft allowed the dynamic photochemical activation of the cofactor-mediated biocatalytic cascade on the spatially biocatalytic assembly on the scaffold. Furthermore, photoinduced "mechanical" switchable and reversible unlocking and closing of nanoholes in the origami frameworks allow the "ON" and "OFF" operation of DNAzyme units in the nanoholes, confined environments. The future challenges and potential applications of dynamic nucleic acid/enzyme and DNAzyme conjugates are discussed in the conclusion paragraph.

Abstract
A finite state machine (FSM, or automaton) is an abstract machine that can switch among a finite number of states in response to temporally ordered inputs, which allows storage and processing of information in an order-sensitive manner. In recent decades, DNA molecules have been actively exploited to develop information storage and nanoengineering materials, which hold great promise for smart nanodevices and nanorobotics under the framework of FSM. In this review, we summarize recent progress in utilizing DNA self-assembly and DNA nanostructures to implement FSMs. We describe basic principles for representative DNA FSM prototypes and highlight their advantages and potential in diverse applications. The challenges in this field and future directions have also been discussed.

Abstract
Photoresponsive nucleic acids attract growing interest as functional constituents in materials science. Integration of photoisomerizable units into DNA strands provides an ideal handle for the reversible reconfiguration of nucleic acid architectures by light irradiation, triggering changes in the chemical and structural properties of the nanostructures that can be exploited in the development of photoresponsive functional devices such as machines, origami structures and ion channels, as well as environmentally adaptable 'smart' materials including nanoparticle aggregates and hydrogels. Moreover, photoresponsive DNA components allow control over the composition of dynamic supramolecular ensembles that mimic native networks. Beyond this, the modification of nucleic acids with photosensitizer functionality enables these biopolymers to act as scaffolds for spatial organization of electron transfer reactions mimicking natural photosynthesis. This review provides a comprehensive overview of these exciting developments in the design of photoresponsive DNA materials, and showcases a range of applications in catalysis, sensing and drug delivery/release. The key challenges facing the development of the field in the coming years are addressed, and exciting emergent research directions are identified.

Abstract
Strand displacement reactions are important bricks for the construction of various DNA nanodevices, among which the toehold-mediated strand displacement reaction is the most prevalently adopted. However, only a limited number of tools could be used to finely regulate the toehold reaction, thus restricting DNA nanodevices from being more multifunctional and powerful. Herein, we developed a regulation tool, Clip, and achieved multiple regulatory functions, including subtle adjustment of the reaction rates, allosteric strand displacement, selective activation, and resetting of the reaction. Taking advantages of the multiple functions, we constructed Clip-toehold-based DNA walking machines. They showed behaviors of controllable walking, concatenation, and programmable pathways. Furthermore, we built Clip-toehold-based AND and OR logic gates and integrated those logic gates to construct multilayer circuits, which could be reset and reused to process different input signals. We believe that the proposed Clip tool has expanded the functionality of DNA strand displacement-based nanodevices to a much more complex and diverse level and anticipate that the tool will be widely adopted in DNA nanotechnology.

Abstract
Models for gene expression instability by noncanonical DNA-nanostructures are introduced. The systems consist of a promoter-template scaffold that acts as a polymerization/nicking machinery that models, in the presence of polymerase/Nt.BbvCI and dNTPs, the autonomous synthesis of displaced strands mimicking the native "genes". Incorporation of noncanonical DNA structures into the scaffolds consisting of Sr2+-ion-stabilized G-quadruplexes, T-A·T triplexes, or ATP-aptamer complexes results in the perturbation of the polymerization/nicking DNA machineries and the synthesis of displaced strands-"genes" exhibiting other structures. By the dissociation of the noncanonical blockage units, the regeneration of the synthesis of the original intact displaced strands-"genes" is demonstrated. The study introduces conceptual means to eliminate destructive gene expression instability pathways.

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
The use of dynamic, self-assembled DNA nanostructures in the context of nanorobotics requires fast and reliable actuation mechanisms. We therefore created a 55-nanometer-by-55-nanometer DNA-based molecular platform with an integrated robotic arm of length 25 nanometers, which can be extended to more than 400 nanometers and actuated with externally applied electrical fields. Precise, computer-controlled switching of the arm between arbitrary positions on the platform can be achieved within milliseconds, as demonstrated with single-pair Förster resonance energy transfer experiments and fluorescence microscopy. The arm can be used for electrically driven transport of molecules or nanoparticles over tens of nanometers, which is useful for the control of photonic and plasmonic processes. Application of piconewton forces by the robot arm is demonstrated in force-induced DNA duplex melting experiments.

Abstract
Reliable and accurate detection of telomerase activity is crucial to better understand its role in cancer cells and to further explore its function in cancer diagnosis and treatment. Here, we construct a smart DNA tweezer (DT) for detection of telomerase activity. The DT is assembled by three specially designed single-stranded oligonucleotides: a central strand dually labeled with donor/acceptor fluorophores and two arm strands containing overhangs complementary to telomerase reaction products (TRPs). It can get closed through hybridization with TRPs and get reopen through strand displacement reaction by TRPs' complementary sequences. First, under the action of telomerase, telomerase binding substrates (TS) are elongated to generate TRPs ended with telomeric repeats (TTAGGG) n. TRPs hybridize with the two arm overhangs cooperatively and strain DT to closed state, inducing an increased fluorescence resonance energy transfer (FRET) efficiency, which is utilized for telomerase activity detection. Second, upon introduction of a removal strand (RS) complementary to TRPs, the closed DT is relaxed to open state via the toehold-mediated strand displacement, inducing a decreased FRET efficiency, which is utilized for determination of TRP length distribution. The detection limit of telomerase activity is equivalent to 141 cells/μL for HeLa cells, and telomerase-active cellular extracts can be differentiated from telomerase-inactive cellular extracts. Furthermore, TRPs owning 1, 2, 3, 4, and ≥5 telomeric repeats are identified to account for 25.6%, 20.5%, 15.7%, 12.5%, and 25.7%, respectively. The proposed strategy will offer a new approach for reliable, accurate detection of telomerase activity and product length distribution for deeper studying its role and function in cancer.

Abstract
We describe an isothermal, enzyme-free method to detect single nucleotide differences between oligonucleotides of close homology. The approach exploits kinetic differences in toe-hold-mediated, nucleic acid strand-displacement reactions to detect single nucleotide polymorphisms (SNPs) with essentially "digital" precision. The theoretical underpinning, experimental analyses, predictability, and accuracy of this new method are reported. We demonstrate detection of biologically relevant SNPs and single nucleotide differences in the let-7 family of microRNAs. The method is adaptable to microarray formats, as demonstrated with on-chip detection of SNP variants involved in susceptibility to the therapeutic agents abacavir, Herceptin, and simvastatin.

Abstract
The synthesis, purification, and structure characterization of a seven-ring interlocked DNA catenane is described. The design of the seven-ring catenane allows the dynamic reconfiguration of any of the four rings (R1, R3, R4, and R6) on the catenane scaffold, or the simultaneous switching of any combination of two, three, or all four rings to yield 16 different isomeric states of the catenane. The dynamic reconfiguration across the states is achieved by implementing the strand-displacement process in the presence of appropriate fuel/antifuel strands and is probed by fluorescence spectroscopy. Each of the 16 isomers of the catenane can be transformed into any of the other isomers, thus allowing for 240 dynamic transitions within the system.

Abstract
The base sequence in nucleic acids encodes substantial structural and functional information into the biopolymer. This encoded information provides the basis for the tailoring and assembly of DNA machines. A DNA machine is defined as a molecular device that exhibits the following fundamental features. (1) It performs a fuel-driven mechanical process that mimics macroscopic machines. (2) The mechanical process requires an energy input, "fuel." (3) The mechanical operation is accompanied by an energy consumption process that leads to "waste products." (4) The cyclic operation of the DNA devices, involves the use of "fuel" and "anti-fuel" ingredients. A variety of DNA-based machines are described, including the construction of "tweezers," "walkers," "robots," "cranes," "transporters," "springs," "gears," and interlocked cyclic DNA structures acting as reconfigurable catenanes, rotaxanes, and rotors. Different "fuels", such as nucleic acid strands, pH (H⁺/OH⁻), metal ions, and light, are used to trigger the mechanical functions of the DNA devices. The operation of the devices in solution and on surfaces is described, and a variety of optical, electrical, and photoelectrochemical methods to follow the operations of the DNA machines are presented. We further address the possible applications of DNA machines and the future perspectives of molecular DNA devices. These include the application of DNA machines as functional structures for the construction of logic gates and computing, for the programmed organization of metallic nanoparticle structures and the control of plasmonic properties, and for controlling chemical transformations by DNA machines. We further discuss the future applications of DNA machines for intracellular sensing, controlling intracellular metabolic pathways, and the use of the functional nanostructures for drug delivery and medical applications.

Abstract
Logic gates are devices that can perform logical operations by transforming a set of inputs into a predictable single detectable output. The hybridization properties, structure, and function of nucleic acids can be used to make DNA-based logic gates. These devices are important modules in molecular computing and biosensing. The ideal logic gate system should provide a wide selection of logical operations, and be integrable in multiple copies into more complex structures. Here we show the successful construction of a small DNA-based logic gate complex that produces fluorescent outputs corresponding to the operation of the six Boolean logic gates AND, NAND, OR, NOR, XOR, and XNOR. The logic gate complex is shown to work also when implemented in a three-dimensional DNA origami box structure, where it controlled the position of the lid in a closed or open position. Implementation of multiple microRNA sensitive DNA locks on one DNA origami box structure enabled fuzzy logical operation that allows biosensing of complex molecular signals. Integrating logic gates with DNA origami systems opens a vast avenue to applications in the fields of nanomedicine for diagnostics and therapeutics.

Abstract
Fast and efficient transport of molecular cargoes along tracks or on supramolecular platforms is an important prerequisite for the development of future nanorobotic systems and assembly lines. Here, we study the diffusive transport of DNA cargo strands bound to a supramolecular DNA origami structure via an extended tether arm. For short distances (on the order of a few nanometers), transport from a start to a target site is found to be less efficient than for direct transfer without tether. For distances on the scale of the origami platform itself, however, cargo transfer mediated by a rigid tether arm occurs very fast and robust, whereas a more flexible, hinged tether is found to be considerably less efficient. Our results suggest diffusive motion on a molecular tether as a highly efficient mechanism for fast transfer of cargoes over long distances.

Abstract
Guanine-rich single-stranded nucleic acids self-assemble into G-quadruplex nanostructures (predominately in the presence of K +-ions). Metalloporphyrins bind to the G-quadruplex nanostructures to form supramolecular assemblies exhibiting unique catalytic, electrocatalytic and photophysical properties. This paper addresses the advances in the characterization and the implementation of the metalloporphyrin/G-quadruplexes complexes for various applications. Out of the different complexes, the most extensively studied complexes are the hemin/G-quadruplex horseradish peroxidase-mimicking DNAzyme and the Zn(II) -protoporphyrin IX-functionalized G-quadruplex. Specifically, the hemin/G-quadruplex was found to act as a catalyst for driving different chemical transformations that mimic the native horseradish peroxidase enzyme, and, also, to function as an electrocatalyst for the reduction of H 2 O 2. Also, the hemin/G-quadruplex stimulates interesting photophysical and photocatalytic processes such as the electron-transfer quenching of semiconductor quantum dots or the chemiluminescence resonance energy transfer to semiconductor quantum dots. Alternatively, Zn(II) -protoporphyrin IX associated with G-quadruplexes exhibit intensified fluorescence properties. Beyond the straight forward application of the metalloporphyrin/G-quadruplexes as catalysts that stimulate different chemical transformations, the specific catalytic, electrocatalytic and photocatalytic functions of hemin/G-quadruplexes are heavily implemented to develop sophisticated colorimetric, electrochemical, and optical sensing platforms. Also, the unique fluorescence properties of Zn(II) -protoporphyrin IX-functionalized G-quadruplexes are applied to develop fluorescence sensing platforms. The article exemplifies different sensing assays for analyzing DNA, ligand-aptamer complexes and telomerase activity using the metalloporphyrins/G-quadruplexes as transducing labels. Also, the use of the hemin/G-quadruplex as a probe to follow the operations of DNA machines is discussed.

Abstract
We describe here the construction of the DNA self-assembled molecular tweezers and the application of the tweezers for the monitoring of microRNA (miR-141) from human prostate cancer cells. The self-assembly formation of the DNA tweezers and the regulation of the tweezers upon alternative addition of the fuel miR-141 and the anti-fuel strands are characterized by native polyacrylamide gel electrophoresis. The addition of miR-141 to the DNA tweezers turns "off" the tweezers, while subsequent introduction of the anti-fuel strands switches the tweezers back to the "on" state, which verifies the regulatory ability of the tweezers. The miR-141-regulated DNA tweezers are concentration dependent and can be employed for sensitive detection of miR-141 down to 0.6 pM. The DNA tweezers also show high selectivity toward the fuel strand and can be used to monitor miR-141 expression in cancer cells, which provides new opportunities for the application of the dynamic DNA devices in clinical diagnostics.

Abstract
The enzyme-free toehold-mediated strand displacement reaction has shown potential for building programmable DNA circuits, biosensors, molecular machines and chemical reaction networks. Here we report a simple colorimetric method using gold nanoparticles as signal generators for the real-time detection of the product of the strand displacement cascade. During the process the assembled gold nanoparticles can be separated, resulting in a color change of the solution. This assay can also be applied in complex mixtures, fetal bovine serum, and to detect single-base mismatches. These results suggest that this method could be of general utility to monitor more complex enzyme-free strand displacement reaction-based programmable systems or for further low-cost diagnostic applications.

Abstract
Noble metal nanoparticles have attracted much interest in the heterogeneous catalysis. Particularly, efficient manipulation of the responsive catalytic properties of the metal nanoparticles is an interesting topic. In this work, a simple and efficient strategy is developed to regulate the pH-responsive catalytic activities of glucose oxidase (GOx)-mimicking gold nanoparticles (AuNPs). Four DNA strands (regulating strands) that differ slightly in sequences are used to interact non-covalently with citrate-capped AuNPs, resulting in markedly distinct pH-dependent catalytic behavior of AuNPs. This is ascribed to the characteristic pH-induced conformational change of the DNA strands that leads to the different adsorption capability to the NPs surface, as demonstrated by pH-CD profiles of the respective DNA molecules. The pH-dependent catalysis of AuNPs is also encoded with structural information of the double-stranded DNA (including regulating strands and their complementary strands) that has conformation resistant or responsive to pH change. As a result, the catalysis can be programmed into an AND gate, a XNOR gate or a NOT gate, using pH and complementary strand as the inputs, the nanoparticle activity as the output and the regulating strands as the programs. This work can be expanded by engineering the catalytic behavior of noble metal nanoparticles to respond smartly to a variety of environmental stimuli, such as metal ions or light wavelengths. These results may provide insight into understanding ligand-regulated nanometallic catalysis.

Abstract
Aptamer-based fluorescence anisotropy (FA) assays have attracted great interest in recent years. However, a key factor that determines FA value is molar mass, thus limiting the utility of this assay for the detection of small molecules. To solve this problem, streptavidin, as a molar mass amplifier, was used in a hybridization chain reaction (HCR) to construct a target-triggered cyclic assembly of DNA-protein hybrid nanowires for highly sensitive detection of small molecules by fluorescence anisotropy. In this assay, one blocking DNA strand is released by target-aptamer recognition. The DNA then serves as an initiator to trigger enzyme-free autonomous cross-opening of hairpin probes via HCR to form a DNA nanowire for further assembly of streptavidin. Using adenosine triphosphate (ATP) as the small molecule target, this novel dual-amplified, aptamer-based FA assay affords high sensitivity with a detection limit of 100 nM. This limit of detection (LOD) is much lower than that of the disassembly approach without HCR amplification or the assembly strategy without streptavidin. In contrast to the previous turn-off disassembly approaches based on nonspecific interactions between the aptamer probe and amplification moieties, the proposed aptamer-based FA assay method exhibits a turn-on response to ATP, which can increase sensing reliability and reduce the risk of false hits. Moreover, because of its resistance to environmental interferences, this FA assay has been successfully applied for direct detection of 0.5 μM ATP in complex biological samples, including cell media, human urine, and human serum, demonstrating its practicality in real complex biological systems.

Abstract
DNA tweezers are modified with two 10-nm sized Au NPs and one 5-nm sized Au NP. Upon treatment of the tweezers with fuel and antifuel nucleic acid strands, the switchable closure and opening of the tweezers proceed, leading to the control of programmed nanostructures of the tethered NPs. The tweezers are further modified with a single 10-nm sized nanoparticle, and a fluorophore unit (Cy3), positioned at different distinct sites of the tweezers. The reversible and cyclic fluorescence quenching or fluorescence enhancement phenomena, upon the dynamic opening/closure of the different tweezers, are demonstrated.

Abstract
The assembly of DNA machines represents a central effort in DNA nanotechnology. We report on the first DNA rotor system composed of a two-ring catenane. The DNA rotor ring rotates in dictated directions along a wheel, and it occupies three distinct sites. Hg(2+)/cysteine or pH (H(+)/OH(-)) act as fuels or antifuels in positioning the rotor ring. Analysis of the kinetics reveals directional clockwise or anticlockwise population of the target-sites (>85%), and the rotor's direction is controlled by the shortest path on the wheel.

Abstract
Nucleic acid/semiconductor quantum dots (QDs) hybrid systems combine the recognition and catalytic properties of nucleic acids with the unique photophysical features of QDs. These functions of nucleic acid/QDs hybrids are implemented to develop different optical sensing platforms for the detection of DNA, aptamer-substrate complexes, and metal ions. Different photophysical mechanisms including fluorescence, electron transfer quenching, fluorescence resonance energy transfer (FRET), and chemiluminescence resonance energy transfer (CRET) are used to develop the sensor systems. The size-controlled luminescence properties of QDs are further implemented for the multiplexed, parallel analysis of several DNAs, aptamer-substrate complexes, or mixtures of ions. Similarly, methods to amplify the sensing events through the biocatalytic regeneration of the analyte were developed. An additional paradigm in the implementation of nucleic acid/QDs hybrids for sensing applications involves the integration of the systems with electrodes, and the generation of photocurrents as transduction signals for the sensing events. Finally, semiconductor QDs conjugated to functional DNA machines, such as "walker" systems, provide an effective optical label for probing the dynamics and mechanical functions of the molecular devices. The present article addresses the recent advances in the application of nucleic acid/QDs hybrids for sensing applications and DNA nanotechnology, and discusses future perspectives of these hybrid materials.
