Abstract
Smart drug delivery systems (DDSs) that respond to, interact with, or are actuated by biological signals or pathological abnormalities (e.g., the tumor microenvironment) for controllable drug release are appealing therapeutic platforms for cancer treatment. Owing to their inherent self-assembled nature, nucleic acids have emerged as programmable materials for the development of multifunctional structures. In response to external environmental stimuli, DNA response elements can serve as switches to trigger conformational changes in DNA structures. Their stimulus-responsive properties make them promising candidates for constructing smart DDSs, and advancements in DNA response element-based DDSs in the field of biomedicine have been made. This review summarizes different types of DNA response elements, including DNA aptamers, DNAzymes, disulfide bond-modified DNA, pH-responsive DNA motifs, and photocleavable DNA building blocks, and highlights the advancements in DNA response element-based smart DDSs for precise drug release. Finally, future challenges and perspectives in this field are discussed.

Abstract
DNA nanostructures that respond to external stimuli have found applications in several areas such as biosensing, drug delivery and molecular computation. The use of different types of stimuli in a single operation provides another layer of control for the reconfiguration of nucleic acid nanostructures. This work demonstrates the use of a ribonuclease to "unset" a nucleic acid nanodevice based on the paranemic crossover (PX) DNA and specific DNA inputs to "reset" the structure into a juxtaposed DNA (JX2) configuration, resulting in a 180° rotation of the helical domains. Such operations would be useful in translational applications where DNA nanostructures can be designed to reconfigure on the basis of more than one stimulus.

Abstract
One of the highly attractive research directions in the electrochemiluminescence (ECL) field is how to regulate and improve ECL efficiency. Quantum dots (QDs) are highly promising ECL materials due to their adjustable luminescence size and strong luminous efficiency. MoS2 NSs@QDs, an ECL emitter, is synthesized via hydrothermal methods, and its ECL mechanism is investigated using cyclic voltammetry and ECL-potential curves. Then, a stable and vertical attachment of a triplex DNA (tsDNA) probe to the MoS2 nanosheets (NSs) is applied to the electrode. Next, an innovative ECL sensor is courageously empoldered for precise and ultrasensitive detection of target miRNA-199a through the agency of ECL-resonance energy transfer (RET) strategy and a dextrous target-initiated catalytic three-arm DNA junction assembly (CTDJA) based on a toehold strand displacement reaction (TSDR) signal amplification approach. Impressively, the ingenious system not only precisely regulates the distance between energy donor-acceptor pairs leave energy less loss and more ECL-RET efficiency, but also simplifies the operational procedure and verifies the feasibility of this self-assembly process without human intervention. This study can expand MoS2 NSs@QDs utilization in ECL biosensing applications, and the proposed nucleic acid amplification strategy can become a miracle cure for ultrasensitive detecting diverse biomarkers, which helps researchers to better study the tumor mechanism, thereby unambiguously increasing cancer cure rates and reducing the risk of recurrence.

Abstract
The use of DNA triplex association is advantageous for the reconfiguration of dynamic DNA nanostructures through pH alteration and can provide environmental control for both structural changes and molecular signaling. The combination of pH-induced triplex-forming oligonucleotide (TFOs) binding with toehold-mediated strand displacement has recently garnered significant attention in the field of structural DNA nanotechnology. While most previous studies use single-stranded DNA to displace or replace TFOs within the triplex, here we demonstrate that pH alteration allows a DNA duplex, with a toehold assistance, to displace TFOs from the components of another DNA duplex. We examined the dependence of this process on toehold length and show that the pH changes allow for cyclic oscillations between two molecular formations. We implemented the duplex/triplex design onto the surface of 2D DNA origami in the form outlining binary digits 0 or 1 and verified the oscillatory conformational changes between the two formations with atomic force microscopy.

Abstract
DNA-based construction allows the creation of molecular devices that are useful in information storage and processing. Here, we combine the programmability of DNA nanoswitches and stimuli-responsive conformational changes to demonstrate information encoding and graphical readout using gel electrophoresis. We encoded information as 5-bit binary codes for alphanumeric characters using a combination of DNA and RNA inputs that can be decoded using molecular stimuli such as a ribonuclease. We also show that a similar strategy can be used for graphical visual readout of alphabets on an agarose gel, information that is encoded by nucleic acids and decoded by a ribonuclease. Our method of information encoding and processing could be combined with DNA actuation for molecular computation and diagnostics that require a nonarbitrary visual readout.

Abstract
Nanoscale devices that can respond to external stimuli have potential applications in drug delivery, biosensing, and molecular computation. Construction using DNA has provided many such devices that can respond to cues such as nucleic acids, proteins, pH, light, or temperature. However, simultaneous control of molecular devices is still limited. Here, we present orthogonal control of DNA nanoswitches using physical (light) and biochemical (enzyme and nucleic acid) triggers. Each one of these triggers controls the reconfiguration of specific nanoswitches from locked to open states within a mixture and can be used in parallel to control a combination of nanoswitches. Such dynamic control over nanoscale devices allows the incorporation of tunable portions within larger structures as well as spatiotemporal control of DNA nanostructures.

Abstract
Controlling the assembly of molybdenum disulfide (MoS2) layers into static and dynamic superstructures can impact on their use in optoelectronics, energy, and drug delivery. Toward this goal, we present a strategy to drive the assembly of MoS2 layers via the hybridization of complementary DNA linkers. By functionalizing the MoS2 surface with thiolated DNA, MoS2 nanosheets were assembled into mulitlayered superstructures, and the complementary DNA strands were used as linkers. A disassembly process was triggered by the formation of an intramolecular i-motif structure at a cystosine-rich sequence in the DNA linker at acidic pH values. We tested the versatility of our approach by driving the disassembly of the MoS2 superstructures through a different DNA-based mechanism, namely strand displacement. This study demonstrates how DNA can be employed to drive the static and dynamic assembly of MoS2 nanosheets in aqueous solution.

Abstract
DNA has been used in the construction of dynamic DNA devices that can reconfigure in the presence of external stimuli. These nanodevices have found uses in fields ranging from biomedical to materials science applications. Here, we report a DNA nanoswitch that can be reconfigured using ribonucleases (RNases) and explore two applications: biosensing and molecular computing. For biosensing, we show the detection of RNase H and other RNases in relevant biological fluids and temperatures, as well as inhibition by the known enzyme inhibitor kanamycin. For molecular computing, we show that RNases can be used to enable erasing, write protection, and erase-rewrite functionality for information-encoding DNA nanoswitches. The simplistic mix-and-read nature of the ribonuclease-activated DNA nanoswitches could facilitate their use in assays for identifying RNase contamination in biological samples or for the screening and characterization of RNase inhibitors.

Abstract
DNA is now well-established as a nanoscale building material with applications in fields such as biosensing and molecular computation. Molecular processes such as logic gates, nucleic acid circuits, and multiplexed detection have used different readout strategies to measure the output signal. In biosensing, this output can be the diagnosis of a disease biomarker, whereas in molecular computation, the output can be the result of a mathematical operation carried out using DNA. Recent developments have shown that the output of such processes can be displayed graphically as a macroscopic symbol or an alphanumeric character on multiwell plates, microarray chips, gels, lateral flow devices, and DNA origami surfaces. This review discusses the concepts behind such graphical readouts of molecular events, available display platforms, and the advantages and challenges in adapting such methods for practical use. Graphical display systems have the potential to be used in the creation of intelligent computing and sensing devices by which nanoscale binding events are translated into macroscopic visual readouts.
