Electronic control of DNA-based nanoswitches and nanodevices.

ABSTRACT: Here we demonstrate that we can rationally and finely control the functionality of different DNA-based nanodevices and nanoswitches using electronic inputs. To demonstrate the versatility of our approach we have used here three different model DNA-based nanoswitches triggered by heavy metals and specific DNA sequences and a copper-responsive DNAzyme. To achieve electronic-induced control of these DNA-based nanodevices we have applied different voltage potentials at the surface of an electrode chip. The applied potential promotes an electron-transfer reaction that releases from the electrode surface a molecular input that ultimately triggers the DNA-based nanodevice. The use of electronic inputs as a way to finely activate DNA-based nanodevices appears particularly promising to expand the available toolbox in the field of DNA nanotechnology and to achieve a better hierarchical control of these platforms.

Determining the folding and binding free energy of DNA-based nanodevices and nanoswitches using urea titration curves.

Project description:DNA nanotechnology takes advantage of the predictability of DNA interactions to build complex DNA-based functional nanoscale structures. However, when DNA functional and responsive units that are based on non-canonical DNA interactions are employed it becomes quite challenging to predict, understand and control their thermodynamics. In response to this limitation, here we demonstrate the use of isothermal urea titration experiments to estimate the free energy involved in a set of DNA-based systems ranging from unimolecular DNA-based nanoswitches to more complex DNA folds (e.g. aptamers) and nanodevices. We propose here a set of fitting equations that allow to analyze the urea titration curves of these DNA responsive units based on Watson-Crick and non-canonical interactions (stem-loop, G-quadruplex, triplex structures) and to correctly estimate their relative folding and binding free energy values under different experimental conditions. The results described herein will pave the way toward the use of urea titration experiments in the field of DNA nanotechnology to achieve easier and more reliable thermodynamic characterization of DNA-based functional responsive units. More generally, our results will be of general utility to characterize other complex supramolecular systems based on different biopolymers.

Enzyme-Operated DNA-Based Nanodevices.

Project description:Functional molecular nanodevices and nanomachines have attracted a growing interest for their potential use in life science and nanomedicine. In particular, due to their versatility and modularity DNA-based nanodevices appear extremely promising. However, a limitation of such devices is represented by the limited number of molecular stimuli and cues that can be used to control and regulate their function. Here we demonstrate the possibility to rationally control and regulate DNA-based nanodevices using biocatalytic reactions catalyzed by different enzymes. To demonstrate the versatility of our approach, we have employed three model DNA-based systems and three different enzymes (belonging to several classes, i.e., transferases and hydrolases). The possibility to use enzymes and enzymatic substrates as possible cues to operate DNA-based molecular nanodevices will expand the available toolbox of molecular stimuli to be used in the field of DNA nanotechnology and could open the door to many applications including enzyme-induced drug delivery and enzyme-triggered nanostructures assembly.

DNA-Based Nanoswitches: Insights into Electrochemiluminescence Signal Enhancement.

Project description:Electrochemiluminescence (ECL) is a powerful transduction technique that has rapidly gained importance as a powerful analytical technique. Since ECL is a surface-confined process, a comprehensive understanding of the generation of ECL signal at a nanometric distance from the electrode could lead to several highly promising applications. In this work, we explored the mechanism underlying ECL signal generation on the nanoscale using luminophore-reporter-modified DNA-based nanoswitches (i.e., molecular beacon) with different stem stabilities. ECL is generated according to the "oxidative-reduction" strategy using tri-n-propylamine (TPrA) as a coreactant and Ru(bpy)32+ as a luminophore. Our findings suggest that by tuning the stem stability of DNA nanoswitches we can activate different ECL mechanisms (direct and remote) and, under specific conditions, a "digital-like" association curve, i.e., with an extremely steep transition after the addition of increasing concentrations of DNA target, a large signal variation, and low preliminary analytical performance (LOD 22 nM for 1GC DNA-nanoswtich and 16 nM for 5GC DNA-nanoswitch). In particular, we were able to achieve higher signal gain (i.e., 10 times) with respect to the standard "signal-off" electrochemical readout. We demonstrated the copresence of two different ECL generation mechanisms on the nanoscale that open the way for the design of customized DNA devices for highly efficient dual-signal-output ratiometric-like ECL systems.

Orthogonal Control of DNA Nanoswitches with Mixed Physical and Biochemical Cues.

Project description: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.

Ribonuclease-Responsive DNA Nanoswitches.

Project description: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.

Dissipative operation of pH-responsive DNA-based nanodevices.

Project description:We demonstrate here the use of 2-(4-chlorophenyl)-2-cyanopropanoic acid (CPA) and nitroacetic acid (NAA) as convenient chemical fuels to drive the dissipative operation of DNA-based nanodevices. Addition of either of the fuel acids to a water solution initially causes a rapid transient pH decrease, which is then followed by a slower pH increase. We have employed such low-to-high pH cycles to control in a dissipative way the operation of two model DNA-based nanodevices: a DNA nanoswitch undergoing time-programmable open-close-open cycles of motion, and a DNA-based receptor able to release-uptake a DNA cargo strand. The kinetics of the transient operation of both systems can be easily modulated by varying the concentration of the acid fuel added to the solution and both acid fuels show an efficient reversibility which further supports their versatility.

Detecting Chirality in Two-Terminal Electronic Nanodevices.

Project description:Central to spintronics is the interconversion between electronic charge and spin currents, and this can arise from the chirality-induced spin selectivity (CISS) effect. CISS is often studied as magnetoresistance (MR) in two-terminal (2T) electronic nanodevices containing a chiral (molecular) component and a ferromagnet. However, fundamental understanding of when and how this MR can occur is lacking. Here, we uncover an elementary mechanism that generates such an MR for nonlinear response. It requires energy-dependent transport and energy relaxation within the device. The sign of the MR depends on chirality, charge carrier type, and bias direction. Additionally, we reveal how CISS can be detected in the linear response regime in magnet-free 2T nanodevices, either by forming a chirality-based spin-valve using two or more chiral components or by Hanle spin precession in devices with a single chiral component. Our results provide operation principles and design guidelines for chirality-based spintronic nanodevices and technologies.

Stable Domain Assembly of a Monomolecular DNA Quadruplex: Implications for DNA-Based Nanoswitches.

Project description:In the presence of K(+) ions, the 5'-GGGTGGGTGGGTGGG-3' (G3T) sequence folds into a monomolecular quadruplex with unusually high thermal stability and unique optical properties. In this study we report that although single G3T molecules unfold and fold rapidly with overlapping melting and refolding curves, G3T multimers (G3T units covalently attached to each other) demonstrate highly reproducible hysteretic behavior. We demonstrate that this behavior necessitates full-length tandem G3T monomers directly conjugated to each other. Any modification of the tandem sequences eliminates the hysteresis. The experimentally measured kinetic parameters and equilibrium transition profiles suggest a highly specific two-state transition in which the folding and unfolding of the first G3T monomer is rate-limiting for both annealing and melting processes. The highly reproducible hysteretic behavior of G3T multimers has the potential to be used in the design of heat-stimulated DNA switches or transistors.

DNA nanoswitches: a quantitative platform for gel-based biomolecular interaction analysis.

Project description:We introduce a nanoscale experimental platform that enables kinetic and equilibrium measurements of a wide range of molecular interactions using a gel electrophoresis readout. Programmable, self-assembled DNA nanoswitches serve both as templates for positioning molecules and as sensitive, quantitative reporters of molecular association and dissociation. We demonstrated this low-cost, versatile, 'lab-on-a-molecule' system by characterizing ten different interactions, including a complex four-body interaction with five discernible states.

Integration of a photocleavable element into DNA nanoswitches.

Project description:Reconfigurable DNA nanostructures can be designed to respond to external stimuli such as nucleic acids, pH, small molecules and enzymes. In this study, we incorporated photocleavable linkers in DNA strands that trigger a conformational change in binary DNA nanoswitches. We demonstrate control of the output using UV light, with potential applications in biosensing and molecular computation.
