Abstract
Ribonuclease A (RNase A) plays significant roles in several physiological and pathological conditions and can be used as a valuable diagnostic biomarker for human diseases such as myocardial infarction and cancer. Hence, it is of great importance to develop a rapid and cost-effective method for the highly sensitive detection of RNase A. The significance of RNase A assay is further enhanced by the growing attention from the biotechnology and pharmaceutical industries to develop RNA-based vaccines and drugs in large part as a result of the successful development of mRNA vaccines in the COVID-19 pandemic. Herein, we report a label-free method for the detection of RNase A by monitoring its proteolytic cleavage of an RNA substrate in a nanopore. The method is ultra-sensitive with the limit of detection reaching as low as 30 fg per milliliter. Furthermore, sensor selectivity and the effects of temperature, incubation time, metal ion, salt concentration on sensor sensitivity were also investigated.

Abstract
Timely in situ imaging and effective treatment are efficient strategies in improving the therapeutic effect and survival rate of tumor patients. In recent years, there has been rapid progress in the development of DNA nanomaterials for tumor in situ imaging and treatment, due to their unsurpassed structural stability, excellent material editability, excellent biocompatibility and individual endocytic pathway. Tetrahedral framework nucleic acids (tFNAs), are a typical example of DNA nanostructures demonstrating superior stability, biocompatibility, cell-entry performance, and flexible drug-loading ability. tFNAs have been shown to be effective in achieving timely tumor in situ imaging and precise treatment. Therefore, the progress in the fabrication, characterization, modification and cellular internalization pathway of tFNAs-based functional systems and their potential in tumor in situ imaging and treatment applications were systematically reviewed in this article. In addition, challenges and future prospects of tFNAs in tumor in situ imaging and treatment as well as potential clinical applications were discussed.

Abstract
Wounds are one of the most common health issues, and the cost of wound care and healing has continued to increase over the past decade. In recent years, there has been growing interest in developing innovative strategies to enhance the efficacy of wound healing. Tetrahedral framework nucleic acids (tFNAs) have emerged as a promising tool for wound healing applications due to their unique structural and functional properties. Therefore, it is of great significance to summarize the applications of tFNAs for wound healing. This review article provides a comprehensive overview of the potential of tFNAs as a novel therapeutic approach for wound healing. In this review, we discuss the possible mechanisms of tFNAs in wound healing and highlight the role of tFNAs in modulating key processes involved in wound healing, such as cell proliferation and migration, angiogenesis, and tissue regeneration. The targeted delivery and controlled release capabilities of tFNAs offer advantages in terms of localized and sustained delivery of therapeutic agents to the wound site. In addition, the latest research progress on tFNAs in wound healing is systematically introduced. We also discuss the biocompatibility and biosafety of tFNAs, along with their potential applications and future directions for research. Finally, the current challenges and prospects of tFNAs are briefly discussed to promote wider applications.

Abstract
Human apurinic/pyrimidine endonuclease 1 (APE1) played a critical role in the occurrence, progress and prognosis of tumors through overexpression and subcellular localization. Thus, it has become an important target for enhancing the sensitivity of tumor cells to radiotherapy and chemotherapy. Therefore, detecting and imaging its intracellular activity is of great significance for inhibitor discovery, cancer diagnosis and therapy. In this work, using DNA-based nanoprobe, we developed a new method for monitor intracellular APE1 activity. The detecting system was consisted by single fluorophore labeled hairpin probe and reduced graphene oxide (rGO). The in vitro result showed that a liner response of the detection method ranged from 0.02 U/mL to 2 U/mL with a limit of detection of 0.02 U/mL. Furthermore, this strategy possessing high specificity was successfully applied for APE1-related inhibitor screening using intracellular fluorescence imaging. Panaxytriol, an effective inhibitor of APE1 activity, was screened from traditional Chinese medicine (TCM) and its effect on APE1 activity was monitored in real time in A549 cells. In summary, this sensitive and specific APE1 detection technology is expected to provide an assistance for APE1-related inhibitor screening and diseases diagnosis.

Abstract
Ribonuclease H is essential for the research and development of complex pathema. The high rigidity and versatility of DNA tetrahedrons means they are often used in biosensing systems. Inspired by "radar" technology, we proposed a radar-like monitor to detect RNase H activity in vitro and in situ by integrating DNA tetrahedral elements. The structure of a radar-like monitor was self-assembled from five customized single nucleic acid strands. Four DNA strands were assembled as DNA tetrahedrons with a long strand labeled by Dabcyl (quencher) at one of the apexes, while the fifth strand (DNA-RNA heterozygous strand) was labeled with a FAM (Fluorophore) hybrid with a long strand. The fluorescence was quenched because the fluorophore and the quencher were very close. In the presence of RNase H, the RNA chain was hydrolyzed and the fluorophore released, resulting in fluorescence recovery. The radar-like monitor was used to detect the RNase H activity in vitro with a detection limit of 0.01 U mL-1. Based on the RNase H activity detection and the inhibitory effect of natural-compounds-targeting RNase H, three inhibitors were obtained among 35 compounds extracted from Panax japonicus. Therefore, the radar-like monitor was successfully used to detect RNase H activity in situ due to the long-term anti-DNase I effect of the RNA/DNA hybrid structure and DNA tetrahedrons structure. Overall, this radar-like monitor can effectively avoid false-positive signals and significantly improve the accuracy, precision, and reliability of detection. It is expected that the development of such an intelligent nano-platform will open the door to cancer diagnosis and treatment in clinical systems.

Abstract
The chemical and self-assembly properties of nucleic acids make them ideal for the construction of discrete structures and stimuli-responsive devices for a diverse array of applications. Amongst the various three-dimensional assemblies, DNA tetrahedra are of particular interest, as these structures have been shown to be readily taken up by the cell, by the process of caveolin-mediated endocytosis, without the need for transfection agents. Moreover, these structures can be readily modified with a diverse range of pendant groups to confer greater functionality. This minireview highlights recent advances related to applications of this interesting DNA structure including the delivery of therapeutic agents ranging from small molecules to oligonucleotides in addition to its use for sensing and imaging various species within the cell.

Abstract
DNA nanotechnology is a unique field that provides simple yet robust design techniques for self-assembling nanoarchitectures with extremely high potential for biomedical applications. Though the field began to exploit DNA to build various nanoscale structures, it has now taken a different path, diverging from the creation of complex structures to functional DNA nanodevices that explore various biological systems and mechanisms. Here, we present a brief overview of DNA nanotechnology, summarizing the key strategies for construction of various DNA nanodevices, with special focus on three-dimensional (3D) nanocages or polyhedras. We then discuss biological applications of 3D DNA nanocages, particularly tetrahedral DNA cages, in their ability to program and modulate cellular systems, in biosensing, and as tools for targeted therapeutics. We conclude with a final discussion on challenges and perspectives of 3D DNA nanodevices in biomedical applications.
