DNA Nanotech: Unleashing RCA's Potential
The Miniature Revolution: How Rolling Circle Amplification Drives DNA Nanotechnology Imagine building intricate structures with the same building blocks that make up your DNA. This isn't science fiction – it's the fascinating world of DNA nanotechnology, where we use the inherent properties of DNA to create nanoscale machines and materials. And at the heart of this revolution lies a powerful tool: Rolling Circle Amplification (RCA). RCA is like a microscopic photocopying machine for DNA. It takes a small circular template and uses a special enzyme called DNA polymerase to repeatedly copy it, creating long, single-stranded DNA molecules that can then be used as building blocks for complex nanostructures. Think of it as taking a single LEGO brick and turning it...
