Abstract
DNA nanotechnology has now enabled the self-assembly of almost any prescribed 3-dimensional nanoscale structure in large numbers and with high fidelity. These structures are also amenable to site-specific modification with a variety of small molecules ranging from drugs to reporter dyes. Beyond obvious application in biotechnology, such DNA structures are being pursued as programmable nanoscale optical breadboards where multiple different/identical fluorophores can be positioned with sub-nanometer resolution in a manner designed to allow them to engage in multistep excitonic energy-transfer (ET) via Förster resonance energy transfer (FRET) or other related processes. Not only is the ability to create such complex optical structures unique, more importantly, the ability to rapidly redesign and prototype almost all structural and optical analogues in a massively parallel format allows for deep insight into the underlying photophysical processes. Dynamic DNA structures further provide the unparalleled capability to reconfigure a DNA scaffold on the fly in situ and thus switch between ET pathways within a given assembly, actively change its properties, and even repeatedly toggle between two states such as on/off. Here, we review progress in developing these composite materials for potential applications that include artificial light harvesting, smart sensors, nanoactuators, optical barcoding, bioprobes, cryptography, computing, charge conversion, and theranostics to even new forms of optical data storage. Along with an introduction into the DNA scaffolding itself, the diverse fluorophores utilized in these structures, their incorporation chemistry, and the photophysical processes they are designed to exploit, we highlight the evolution of DNA architectures implemented in the pursuit of increased transfer efficiency and the key lessons about ET learned from each iteration. We also focus on recent and growing efforts to exploit DNA as a scaffold for assembling molecular dye aggregates that host delocalized excitons as a test bed for creating excitonic circuits and accessing other quantum-like optical phenomena. We conclude with an outlook on what is still required to transition these materials from a research pursuit to application specific prototypes and beyond.

Abstract
The dissipative translocation of the Zn2+ ion between two prototypical coordination complexes has been investigated by combining X-ray absorption and 1H NMR spectroscopy. An integrated experimental and theoretical approach, based on state-of-the-art Multivariate Curve Resolution and DFT based theoretical analyses, is presented as a means to understand the concentration time evolution of all relevant Zn and organic species in the investigated processes, and accurately characterize the solution structures of the key metal coordination complexes. Specifically, we investigate the dissipative translocation of the Zn2+ cation from hexaaza-18-crown-6 to two terpyridine moieties and back again to hexaaza-18-crown-6 using 2-cyano-2-phenylpropanoic acid and its para-chloro derivative as fuels. Our interdisciplinary approach has been proven to be a valuable tool to shed light on reactive systems containing metal ions that are silent to other spectroscopic methods. These combined experimental approaches will enable future applications to chemical and biological systems in a predictive manner.

Abstract
The synthesis of stimuli-responsive hybrid structures composed of drug-loaded UiO-66 metal-organic framework nanoparticles, NMOFs, locked by DNA tetrahedra gates is presented. The hybrid systems combine the high loading capacity of drugs in the porous NMOFs and the effective cell permeation properties of the DNA tetrahedra. The nucleic acid-functionalized UiO-66 NMOFs are loaded with drugs (doxorubicin, DOX, or camptothecin, CPT) or with dyes as drug models (Rhodamine 6G or fluorescein) and used to prepare stimuli-responsive carriers. In this study, two different stimuli-responsive NMOFs are presented. One system introduces the drug-loaded NMOFs locked by pH-responsive DNA tetrahedra. At acidic pH values, the gating tetrahedra are dissociated from the NMOFs through the formation of i-motif structures, resulting in the unlocking of the NMOFs and the release of the drugs. In addition, the tetrahedra gates are modified with AS1411 aptamer tethers, and these target the drug-loaded NMOFs to nucleolin receptors overexpressed in certain malignant cells. A second system involves the preparation of NMOFs loaded with drugs/dyes and gated by the microRNA (miRNA)-responsive tetrahedra (miRNA-21 or miRNA-155). In the presence of miRNAs, the dissociation of miRNA-responsive tetrahedra from the NMOFs leads to the unlocking of the NMOFs and the release of the loads. Further developments of the miRNA-responsive tetrahedra-gated hybrid carriers include the following. (i) By appropriate engineering of the miRNA gating units, the exonuclease III (Exo III)-amplified unlocking of the carriers, through the regeneration of the miRNA triggers, and the enhanced release of the loaded drugs are demonstrated. (ii) By applying mixtures of miRNA-21-responsive DNA tetrahedra-gated DOX-loaded NMOFs and miRNA-155-responsive DNA tetrahedra-gated CPT-loaded NMOFs, the multiplexed miRNA-21/miRNA-155-dictated release of the drugs is demonstrated. As compared to the analog DNA duplex-modified NMOFs, DNA tetrahedra-gated, drug-loaded NMOFs permeation into malignant MDA-MB-231 breast cancer cells presents more effective cell permeation. Effective and selective cytotoxicity toward the malignant cells, as compared to nonmalignant epithelial MCF-10A breast cells, is demonstrated due to the acidic pH, present in cancer cells, or the miRNA-21, present in MDA-MB-231 malignant cells.

Abstract
The mechanical properties of DNA have enabled it to be a structural and sensory element in many nanotechnology applications. While specific base-pairing interactions and secondary structure formation have been the most widely utilized mechanism in designing DNA nanodevices and biosensors, the intrinsic mechanical rigidity and flexibility are often overlooked. In this article, we will discuss the biochemical and biophysical origin of double-stranded DNA rigidity and how environmental and intrinsic factors such as salt, temperature, sequence, and small molecules influence it. We will then take a critical look at three areas of applications of DNA bending rigidity. First, we will discuss how DNA's bending rigidity has been utilized to create molecular springs that regulate the activities of biomolecules and cellular processes. Second, we will discuss how the nanomechanical response induced by DNA rigidity has been used to create conformational changes as sensors for molecular force, pH, metal ions, small molecules, and protein interactions. Lastly, we will discuss how DNA's rigidity enabled its application in creating DNA-based nanostructures from DNA origami to nanomachines.

Abstract
Hybridization probes are RNA or DNA oligonucleotides or their analogs that bind to specific nucleotide sequences in targeted nucleic acids (analytes) via Watson-Crick base pairs to form probe-analyte hybrids. Formation of a stable hybrid would indicate the presence of a DNA or RNA fragment complementary to the known probe sequence. Some of the well-known technologies that rely on nucleic acid hybridization are TaqMan and molecular beacon (MB) probes, fluorescent in situ hybridization (FISH), polymerase chain reaction (PCR), antisense, siRNA, and CRISPR/cas9, among others. Although invaluable tools for DNA and RNA recognition, hybridization probes suffer from several common disadvantages including low selectivity under physiological conditions, low affinity to folded single-stranded RNA and double-stranded DNA, and high cost of dye-labeled and chemically modified probes. Hybridization probes are evolving into multifunctional molecular devices (dubbed here "multicomponent probes", "DNA machines", and "DNA robots") to satisfy complex and often contradictory requirements of modern biomedical applications. In the definition used here, "multicomponent probes" are DNA probes that use more than one oligonucleotide complementary to an analyzed sequence. A "DNA machine" is an association of a discrete number of DNA strands that undergoes structural rearrangements in response to the presence of a specific analyte. Unlike multicomponent probes, DNA machines unify several functional components in a single association even in the absence of a target. DNA robots are DNA machines equipped with computational (analytic) capabilities. This Account is devoted to an overview of the ongoing evolution of hybridization probes to DNA machines and robots. The Account starts with a brief excursion to historically significant and currently used instantaneous probes. The majority of the text is devoted to the design of (i) multicomponent probes and (ii) DNA machines for nucleic acid recognition and analysis. The fundamental advantage of both designs is their ability to simultaneously address multiple problems of RNA/DNA analysis. This is achieved by modular design, in which several specialized functional components are used simultaneously for recognition of RNA or DNA analytes. The Account is concluded with the analysis of perspectives for further evolution of DNA machines into DNA robots.

Abstract
Molecular logic devices (MLDs) constructed from DNA are promising for applications in bioanalysis, computing, and other applications requiring Boolean logic. These MLDs accept oligonucleotide inputs and generate fluorescence output through changes in structure. Although fluorescent dyes are most common in MLD designs, nontraditional luminescent materials with unique optical properties can potentially enhance MLD capabilities. In this context, luminescent lanthanide complexes (LLCs) have been largely overlooked. Here, we demonstrate a set of high-contrast DNA photonic logic gates based on toehold-mediated strand displacement and time-gated FRET. The gates include NAND, NOR, OR, and AND designs that accept two unlabeled target oligonucleotide sequences as inputs. Bright "true" output states utilize time-gated, FRET-sensitized emission from an Alexa Fluor 546 (A546) dye acceptor paired with a luminescent terbium cryptate (Tb) donor. Dark "false" output states are generated through either displacement of the A546, or through competitive and sequential quenching of the Tb or A546 by a dark quencher. Time-gated FRET and the long luminescence lifetime and spectrally narrow emission lines of the Tb donor enable 4-10-fold contrast between Boolean outputs, ≤10% signal variation for a common output, multicolor implementation of two logic gates in parallel, and effective performance in buffer and serum. These metrics exceed those reported for many other logic gate designs with only fluorescent dyes and with other non-LLC materials. Preliminary three-input AND and NAND gates are also demonstrated. The powerful combination of an LLC FRET donor with DNA-based logic gates is anticipated to have many future applications in bioanalysis.

Abstract
This feature article addresses the implementation of catalytic nucleic acids as functional units for the construction of logic gates and computing circuits, and discusses the future applications of these systems. The assembly of computational modules composed of DNAzymes has led to the operation of a universal set of logic gates, to field programmable logic gates and computing circuits, to the development of multiplexers/demultiplexers, and to full-adder systems. Also, DNAzyme cascades operating as logic gates and computing circuits were demonstrated. DNAzyme logic systems find important practical applications. These include the use of DNAzyme-based systems for sensing and multiplexed analyses, for the development of controlled release and drug delivery systems, for regulating intracellular biosynthetic pathways, and for the programmed synthesis and operation of cascades.

Abstract
AbstractThe development of multicomponent chemical systems that can perform predetermined functions under external control – i.e., molecular devices – is a challenging task in chemistry and a fascinating objective in the frame of a bottom-up approach to nanostructures. Photochromic units undergo profound changes in their chemical and/or electronic structure upon light excitation, and are highly interesting for the construction of photocontrollable molecular devices, machines and materials. The E–Z photoisomerization of azobenzene – owing to its high efficiency, excellent reversibility and significant physico-chemical differences between the two forms – is a highly useful reaction in this regard. Azobenzene photoisomerization has been known for almost 80 years and has been exploited to implement light-induced functionalities with a large variety of compounds, biomolecules, nanosystems and materials. Here we present some of our recent investigations highlighting how this outstanding photochrome can be utilized to develop (supra)molecular systems with valuable light-induced functionalities.

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
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.
