Summary: In this study, a reconfigurable nanophotonic heterostructure was constructed by integrating an upconversion nanoparticle (UCNP) and a gold nanorod (AuNR) on a DNA origami switch (DOS) template. The UCNP exhibited unique anti-Stokes luminescence in the near-infrared (NIR) region and could be excited by 980 laser light to generate visible light emission. The construction of this nanophotonic heterostructure expands the applications of DNA origami-based nanophotonic systems and holds potential in optical biosensing and imaging.

Summary: This article introduces the low-temperature opto-thermophoretic tweezers (HOTTs) technology, which achieves low-power trapping of diverse colloids and biological cells at sub-ambient temperatures through an environmental cooling strategy. At the same time, HOTTs can also suppress thermal damage. With their noninvasiveness and versatile capabilities, HOTTs have great potential for research and applications in materials science and biotechnology.

Summary: The study demonstrates a DNA origami switch that utilizes the transition from double-stranded DNA to single-stranded DNA to drive a reversible conformational change. By using the unique properties of DNA, the switch exerts a contractive force produced by the extended single-stranded DNA to achieve large-scale motion. The operation of this switch is shown through various microscopy techniques, illustrating the intricate forces at play in nanoscale physical systems operating in fluids.

Summary: Integrating dissimilar materials at the nanoscale is crucial for modern electronics and optoelectronics. Researchers have developed a DNA origami-encoded strategy for integrating silica-metal heterostructures and revealed the underlying mechanisms. By programming the densities and lengths of protruding dsDNA strands on DNA origami, high site-addressability of material deposition was achieved.
