Abstract
In this paper, the one-pot method is used to make the four DNA strands complement each other to construct the basic framework for DNA tetrahedral tweezers. To regulate the opening and closing of DNA tetrahedral tweezers, DNA strands with a high amount of T-base sequences is partially complementary to the tetrahedral framework. Hg2+ can form T-Hg-T hairpin structures with T-base. When DNA tetrahedral tweezers encounter Hg2+, the T-Hg-T structure is formed to shorten the connecting chain, and the tightening force causes the DNA tweezers to change from an open state to a closed state. Conversely, changes in fluorescence intensity due to the structure change can be used to detect the presence of Hg2+.

Abstract
Metal-mediated DNA (mmDNA) presents a pathway toward engineering bioinorganic and electronic behavior into DNA devices. Many chemical and biophysical forces drive the programmable chelation of metals between pyrimidine base pairs. Here, we developed a crystallographic method using the three-dimensional (3D) DNA tensegrity triangle motif to capture single- and multi-metal binding modes across granular changes to environmental pH using anomalous scattering. Leveraging this programmable crystal, we determined 28 biomolecular structures to capture mmDNA reactions. We found that silver(I) binds with increasing occupancy in T-T and U-U pairs at elevated pH levels, and we exploited this to capture silver(I) and mercury(II) within the same base pair and to isolate the titration points for homo- and heterometal base pair modes. We additionally determined the structure of a C-C pair with both silver(I) and mercury(II). Finally, we extend our paradigm to capture cadmium(II) in T-T pairs together with mercury(II) at high pH. The precision self-assembly of heterobimetallic DNA chemistry at the sub-nanometer scale will enable atomistic design frameworks for more elaborate mmDNA-based nanodevices and nanotechnologies.

Abstract
Food safety has always been a major global challenge to human health and the effective detection of harmful substances in food can reduce the risk to human health. However, the food industry has been plagued by a lack of effective and sensitive safety monitoring methods due to the tension between the cost and effectiveness of monitoring. DNA-based hydrogels combine the advantages of biocompatibility, programmability, the molecular recognition of DNA molecules, and the hydrophilicity of hydrogels, making them a hotspot in the research field of new nanomaterials. The stimulus response property greatly broadens the function and application range of DNA hydrogel. In recent years, DNA hydrogels based on stimulus-responsive mechanisms have been widely applied in the field of biosensing for the detection of a variety of target substances, including various food contaminants. In this review, we describe the recent advances in the preparation of stimuli-responsive DNA hydrogels, highlighting the progress of its application in food safety detection. Finally, we also discuss the challenges and future application of stimulus-responsive DNA hydrogels.

Abstract
The investigation of the interaction between metal ions and DNA has always attracted much attention in the fields of bioinorganic chemistry, supramolecular coordination chemistry, and DNA nanotechnology. Its mode of action can be simply divided into two aspects. On the one hand, it is non-specific electrostatic adsorption, mainly including Na+, K+, Mg2+, Ca2+ and other physiologically regulating ions; on the other hand, it is specific covalent binding, such as Pt2+, Hg2+, Ag+ and other heavy metal ions. This article focuses on the mechanism of action between Ag+ and DNA mismatch pair C-C, and summarizes its main characterization methods and various applications. It aims to provide a certain reference for the field of biological devices. With the development of cryo-electron microscopy and liquidcell TEM, the structure of C-Ag+-C is expected to be further characterized, which will be more widely used.

Abstract
The incorporation of metal ions into nucleic acids by means of metal-mediated base pairs represents a promising and prominent strategy for the site-specific decoration of these self-assembling supramolecules with metal-based functionality. Over the past 20 years, numerous nucleoside surrogates have been introduced in this respect, broadening the metal scope by providing perfectly tailored metal-binding sites. More recently, artificial nucleosides derived from natural purine or pyrimidine bases have moved into the focus of AgI -mediated base pairing, due to their expected compatibility with regular Watson-Crick base pairs. This minireview summarizes these advances in metal-mediated base pairing but also includes further recent progress in the field. Moreover, it addresses other aspects of metal-modified nucleic acids, highlighting an expansion of the concept to metal-mediated base triples (in triple helices and three-way junctions) and metal-mediated base tetrads (in quadruplexes). For all types of metal-modified nucleic acids, proposed or accomplished applications are briefly mentioned, too.
