Biosensors are small but smart devices responding to the external stimulus, widely used in many fields including clinical diagnosis, healthcare and environment monitoring, etc. Moreover, there is still a pressing need to fabricate sensitive, stable, reliable sensors at present. DNA origami technology is able to not only construct arbitrary shapes in two/three dimension but also control the arrangement of molecules with different functionalities precisely. The functionalization of DNA origami nanostructure endows the sensing system potential of filling in weak spots in traditional DNA-based biosensor. Herein, we mainly review the construction and sensing mechanisms of sensing platforms based on DNA origami nanostructure according to different signal output strategies. It will offer guidance for the application of DNA origami structures functionalized by other materials. We also point out some promising directions for improving performance of biosensors.

Carbon nanomaterials (CNMs) have attracted extensive attentions on account of their superior electrical, mechanical, optical, and biological properties. However, the dimensional limit and irregular arrangement have hampered their further application. It is necessary to find an easy, efficient and controllable way to assemble CNMs into well‐ordered array. DNA nanotechnology, owning to the advantages of precise programmability, highly structural predictability and spatial addressability, has been widely applied in the assembly of CNMs. Summarizing the progress and achievements in this field will be of great value to related studies. Herein, based on the different dimensions of CNMs containing 0‐dimensional (0D) carbon dots (CDs), fullerenes, 1‐dimensional (1D) carbon nanotubes (CNTs) and 2‐dimensional (2D) graphene, we introduced the conjugation strategies between DNA and CNMs, their different assembly methods and their applications. In addition, we also discuss the existing challenges and future opportunities in the field.

In this paper, an efficient switching pattern to equalize to use only one input DC source and combine the half-bridge the size of transformer is proposed for a multi-level inverter inverters with the boost transformers to make ofthe multi-level using cascaded transformers. It bases on the prior selected inverter. But transformers combined with HBML inverter have harmonic elimination PWM (SHEPWM) method. Because the the different voltage ratings and need to be designed in maximum magnetic flux imposed on each transformer becomes different size each other. In this paper, for reducing harmonics exactly equal each other, all transformers can be designed with of the single-phase inverter, a novel trsformer-combined the same size regardless of their position. Therefore, identical switching method is proposed; accordingly the same size full-bridge inverter units can be utilized, the modularity can be
