Overview

• 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.
