Abstract
Due to the wide range of electrochemical devices available, DNA nanostructures and material-based technologies have been greatly broadened. They have been actively used to create a variety of beautiful nanostructures owing to their unmatched programmability. Currently, a variety of electrochemical devices have been used for rapid sensing of biomolecules and other diagnostic applications. Here, we provide a brief overview of recent advances in DNA-based biomolecular assays. Biosensing platform such as electrochemical biosensor, nanopore biosensor, and field-effect transistor biosensors (FET), which are equipped with aptamer, DNA walker, DNAzyme, DNA origami, and nanomaterials, has been developed for amplification detection. Under the optimal conditions, the proposed biosensor has good amplification detection performance. Further, we discussed the challenges of detection strategies in clinical applications and offered the prospect of this field.

Abstract
In this paper, the glass nanopore technology was proposed to detect a single molecule of starch dissolved in ionic liquid [1-butyl-3-methylimidazolium chloride (BmimCl)]. Firstly, the influence of BmimCl on nanopore detection is discussed. It is found that a certain amount of strong polar ionic liquids will disturb the charge distribution in nanopores and increase the detection noise. Then, by analysis of the characteristic current signal of the conical nanopore, the motion behaviour of starch near the entrance of the nanopore was studied and analysis the dominant ion of starch in the BmimCl dissolution process. Finally, based on nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) spectroscopy simply discussed the mechanism of amylose and amylopectin dissolved in BmimCl. These results confirm that branched chain structure would affect the dissolution of polysaccharides in ionic liquids and the contribution of anions to the dissolution of polysaccharides are dominant. It is further proved that the current signal can be used to judge the charge and structure information of the analyte, and the dissolution mechanism can be assist analyzed at the single molecule level.

Abstract
The deoxyribonucleotide (DNA) molecule is a stable carrier for large amounts of genetic information and provides an ideal storage medium for next-generation information processing technologies. Technologies that process DNA information, representing a cross-disciplinary integration of biology and computer techniques, have become attractive substitutes for technologies that process electronic information alone. The detailed applications of DNA technologies can be divided into three components: storage, computing, and self-assembly. The quality of DNA information processing relies on the accuracy of DNA reading. Nanopore detection allows researchers to accurately sequence nucleotides and is thus widely used to read DNA. In this paper, we introduce the principles and development history of nanopore detection and conduct a systematic review of recent developments and specific applications in DNA information processing involving nanopore detection and nanopore-based storage. We also discuss the potential of artificial intelligence in nanopore detection and DNA information processing. This work not only provides new avenues for future nanopore detection development, but also offers a foundation for the construction of more advanced DNA information processing technologies.
