Abstract
DNA nanotechnology provides an approach to create precise, tunable, and biocompatible nanostructures for biomedical applications. However, the stability of these structures is severely compromised in biological milieu due to their fast degradation by nucleases. Recently, we showed how enzymatic polymerization could be harnessed to grow polynucleotide brushes of tunable length and location on the surface of DNA origami nanostructures, which greatly enhances their nuclease stability. Here, we report on strategies that allow for both spatial and temporal control over polymerization through activatable initiation, cleavage, and regeneration of polynucleotide brushes using restriction enzymes. The ability to site-specifically decorate DNA origami nanostructures with polynucleotide brushes in a spatiotemporally controlled way provides access to "smart" functionalized DNA architectures with potential applications in drug delivery and supramolecular assembly.

Abstract
DNA nanotechnology has provided credible approaches for assembly of three-dimensional (3D) lattices with complex patterns. However, the symmetries are strictly dependent on their initial configurations and difficult to alter via non-thermal treatments. While switchable nucleic acid structures have been employed to construct deformable DNA motifs, it remains challenging to arrange them anisotropically in 3D lattices to trigger directed collective shape transition and dynamic symmetry conversion. In this work, we used octahedral DNA origami frames to synthesize four DNA origami lattices by placing the pH-reactive i-motif sequences in the desired dimensions. Thereinto, lattices with an anisotropic design can switch between simple cubic (SC) and simple tetragonal (ST) upon pH change. Small angle X-ray scattering (SAXS) results reveal the feasibility of obtaining 3D lattices with sensitive responses to external stimuli, expanding the way to obtain low-symmetry lattices.

Abstract
The use of DNA-based nanostructures as probes has led to significant advances in chemical and biological sensing, allowing the detection of analytes in complex media, the understanding of fundamental biological processes, and the ability to diagnose diseases based on molecular signatures. The utility of these structures arises both from DNA's inherent ability to selectively recognize and bind a variety of chemical species and from the unique properties observed when DNA is restructured at the nanoscale. In this Minireview, we chronicle the most commonly used signal transduction strategies that have been interfaced with various DNA-based nanostructures. We discuss the types of analytes and the detection scenarios that are sought after, delineate the advantages and disadvantages of each signaling strategy, and outline the key considerations that guide the selection of each signaling method.

Abstract
Deoxyribonucleic acid (DNA) is a molecular carrier of genetic information that can be fabricated into functional nanomaterials in biochemistry and engineering fields. Those DNA nanostructures, synthesized via Watson-Crick base pairing, show a wide range of attributes along with excellent applicability, precise programmability, and extremely low cytotoxicity in vitro and in vivo. In this review, the applications of functionalized DNA nanostructures in bioimaging and tumor therapy are summarized. We focused on approaches involving DNA origami nanostructures due to their widespread use in previous and current reports. Non-DNA origami nanostructures such as DNA tetrahedrons are also covered. Finally, the remaining challenges and perspectives regarding DNA nanostructures in the biomedical arena are discussed.
