Abstract
One of the fundamental challenges in nanophotonics is to gain full control over nanoscale optical elements. The precise spatiotemporal arrangement determines their interactions and collective behavior. To this end, DNA nanotechnology is employed as an unprecedented tool to create nanophotonic devices with excellent spatial addressability and temporal programmability. However, most of the current DNA-assembled nanophotonic devices can only reconfigure among random or very few defined states. Here, we demonstrate a DNA-assembled rotary plasmonic nanoclock. In this system, a rotor gold nanorod can carry out directional and reversible 360° rotation with respect to a stator gold nanorod, transitioning among 16 well-defined configurations powered by DNA fuels. The full-turn rotation process is monitored by optical spectroscopy in real time. We further demonstrate autonomous rotation of the plasmonic nanoclock powered by DNAzyme-RNA interactions. Such assembly approaches pave a viable route towards advanced nanophotonic systems entirely from the bottom-up. Current DNA-assembled nanophotonic devices can only reconfigure among random or few defined states. Here, the authors demonstrate a DNA-assembled rotary plasmonic nanoclock in which a rotor gold nanorod carries out directional and reversible 360° rotation transitioning among 16 well-defined configurations.

NANO RESEARCH 2019; 12:2900-2907.

Abstract
DNA origami is a promising technology for its reproducibility, flexibility, scalability and biocompatibility. Among the several potential applications, DNA origami has been proposed as a tool for drug delivery and as a contrast agent, since a conformational change upon specific target interaction may be used to release a drug or produce a physical signal, respectively. However, its conformation should be robust with respect to the properties of the medium in which either the recognition or the read-out take place, such as pressure, viscosity and any other unspecific interaction other than the desired target recognition. Here we report on the read-out robustness of a tetragonal DNA-origami/gold-nanoparticle hybrid structure able to change its configuration, which is transduced in a change of its plasmonic properties, upon interaction with a specific DNA target. We investigated its response when analyzed in three different media: aqueous solution, solid support and viscous gel. We show that, once a conformational variation is produced, it remains unaffected by the subsequent physical interactions with the environment.

Abstract
We report here the fabrication of a multiple stimuli-responsive chiral plasmonic system based on the reversible self-assembly of phenylboronic acid-capped gold nanorods (PBA-Au NRs) guided by a supramolecular glycopeptide mimetic template. The plasmonic chiral signals of PBA-Au NRs can be reversibly switched on and off by temperature, light, pH and glucose concentration variations.

Dual Aptamer-Functionalized 3D Plasmonic Metamolecule for Thrombin Sensing. APPLIED SCIENCES-BASEL 2019. [DOI: 10.3390/app9153006] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 01/24/2023]
Abstract
DNA nanotechnology offers the possibility to rationally design structures with emergent properties by precisely controlling their geometry and functionality. Here, we demonstrate a DNA-based plasmonic metamolecule that is capable of sensing human thrombin proteins. The chiral reconfigurability of a DNA origami structure carrying two gold nanorods was used to provide optical read-out of thrombin binding through changes in the displayed plasmonic circular dichroism. In our experiments, each arm of the structure was modified with one of two different thrombin-binding aptamers—thrombin-binding aptamer (TBA) and HD22—in such a way that a thrombin molecule could be sandwiched by the aptamers to lock the metamolecule in a state of defined chirality. Our structure exhibited a Kd of 1.4 nM, which was an order of magnitude lower than those of the individual aptamers. The increased sensitivity arose from the avidity gained by the cooperative binding of the two aptamers, which was also reflected by a Hill coefficient of 1.3 ± 0.3. As we further exploited the strong plasmonic circular dichroism (CD) signals of the metamolecule, our method allowed one-step, high sensitivity optical detection of human thrombin proteins in solution.

Abstract

The key component of nanoplasmonics is metals. For a long time,
gold and silver have been the metals of choice for constructing plasmonic
nanodevices because of their excellent optical properties. However,
these metals possess a common characteristic, i.e., their optical
responses are static. The past decade has been witnessed tremendous
interest in dynamic control of the optical properties of plasmonic
nanostructures. To enable dynamic functionality, several approaches
have been proposed and implemented. For instance, plasmonic nanostructures
can be fabricated on stretchable substrates or on programmable templates
so that the interactions between the constituent metal nanoparticles
and therefore the optical responses of the plasmonic systems can be
dynamically changed. Also, plasmonic nanostructures can be embedded
in tunable dielectric materials, taking advantage of the sensitive
dependence of the localized surface plasmon resonances on the neighboring
environment. Another approach, which is probably the most intriguing
one, is to directly regulate the carrier densities and dielectric
functions of the metals themselves. In this Account, we discuss
a relatively new metal in nanoplasmonics,
magnesium, and its important role in the development of dynamic plasmonic
nanodevices at visible frequencies. We first elucidate the basic optical
properties of Mg and compare it with conventional plasmonic materials
such as Au, Ag, and others. Then we describe a unique characteristic
of Mg, i.e., its reversible phase transitions between the metallic
state and a dielectric state, magnesium hydride, through hydrogenation
and dehydrogenation. This sets the basis for Mg in dynamic nanoplasmonics.
In particular, the structural properties and dielectric functions
of the two distinct states are discussed in detail. Subsequently,
we highlight the experimental investigations of the physical mechanisms
and nanoscale understanding of Mg nanoparticles during hydrogenation
and dehydrogenation. We then introduce a plethora of newly developed
Mg-based dynamic optical nanodevices for applications in plasmonic
chirality switching, dynamic color displays with Mg nanoparticles
and films, and dynamic metasurfaces for ultrathin and flat optical
elements. We also outline strategies to enhance the stability, reversibility,
and durability of Mg-based nanodevices. Finally, we end this Account
by outlining the remaining challenges, possible solutions, and promising
applications in the field of Mg-based dynamic nanoplasmonics. We envision
that Mg-based dynamic nanoplasmonics will not only provide insights
into understanding the catalytic processes of hydrogen diffusion in
metals by optical means but also will open an avenue toward functional
plasmonic nanodevices with tailored optical properties for real-world
applications.

Abstract
Nano-objects with chiral properties attract growing interest due to their relevance for a wide variety of technological applications. For example, chiral nano-objects may be used in characterization platforms that involve chiral molecular recognition of proteins or in the fabrication of nanomechanical devices such as screw-gears or nanoswimmers. Spatial ordering of emitters of circularly polarized light might greatly benefit from the utilization of chiral shapes. Tools developed in DNA nanotechnology now allow precise tailoring of the chiral properties of molecules and materials at various length scales. Among others, they have already been applied to control the handedness of helical shapes (configurational chirality) or the chiral positioning of different-sized nanoparticles at the vertices of tetrahedra (compositional chirality). This work covers some of the key advances and recent developments in the field of chiral DNA nanoarchitectures and discusses their future perspectives and potential applications.

Resonance-enhanced three-photon luminesce via lead halide perovskite metasurfaces for optical encoding. Nat Commun 2019; 10:2085.

Abstract
Lead halide perovskites have emerged as promising materials for photovoltaic and optoelectronic devices. However, their exceptional nonlinear properties have not been fully exploited in nanophotonics yet. Herein we fabricate methyl ammonium lead tri-bromide perovskite metasurfaces and explore their internal nonlinear processes. While both of third-order harmonic generation and three-photon luminescence are generated, the latter one is less affected by the material loss and has been significantly enhanced by a factor of 60. The corresponding simulation reveals that the improvement is caused by the resonant enhancement of incident laser. Interestingly, such kind of resonance-enhanced three-photon luminescence holds true for metasurfaces with a small period number of 4, enabling promising applications of perovskite metasurface in high-resolution nonlinear color nanoprinting and optical encoding. The encoded information ‘NANO’ is visible only when the incident laser is on-resonance. The off-resonance pumping and the single-photon excitation just produce a uniform dark or photoluminescence background. Lead halide perovskites attract high interest as semiconductor materials but their exceptional nonlinear properties have not been fully exploited. Here Fan et al. demonstrate third-order harmonic generation and 60-fold enhanced three-photon luminescence, enabling optical encoding applications.
