Scientists Create Programmable Nanobots Using DNA Origami

University of Sydney researchers develop modular DNA nanostructures with potential applications in medicine, robotics, and materials science.

Researchers at the University of Sydney have pioneered the use of DNA origami to construct programmable nanoscale structures, including a 'nano-dinosaur' and a 'dancing robot.'
The study introduces modular 'voxels'—3D building blocks made from folded DNA strands—that can be assembled into complex shapes with precision.
These nanostructures could enable targeted drug delivery systems, such as nanobots designed to release cancer treatments at precise locations in the body.
The technology also holds promise for creating adaptive materials that respond to environmental changes, like temperature or acidity, with potential applications in electronics and medicine.
Researchers are exploring further uses, including energy-efficient optical signal processing and advanced medical diagnostic tools, leveraging the versatility of DNA nanotechnology.
