➀ Researchers at Columbia University have successfully used DNA to create 3D electronic devices with nanoscale precision, which could significantly enhance computing power by transitioning from 2D to 3D architectures.

➁ This bottom-up approach, based on DNA origami, allows for self-assembly of DNA strands into precise nanostructures, offering a more efficient alternative to traditional top-down etching methods.

➂ The integration of electrodes and semiconductor materials like silicon oxide and tin oxide onto DNA-assembled structures demonstrates their potential application in future microchips, potentially revolutionizing semiconductor manufacturing.

➀ Researchers from the Institute for Molecular Science have improved the speed of DNA-nanoparticle motors by optimizing their design, bringing them closer to the speeds of natural motor proteins.

➁ The DNA-nanoparticle motor uses the 'burnt-bridge' Brownian ratchet mechanism, where the degradation of RNA/DNA bonds propels the motor forward.

➂ By increasing the concentration of RNase H, the speed of the motor was significantly enhanced, though it came at the cost of reduced run length and processivity.
