The miniaturizing technology, called "implosion fabrication," could be applied to anything from developing smaller microscope and cell phone lenses to creating tiny robots that improve everyday life.

Here's how it works: Using a laser, researchers make a structure with absorbent gel -- akin to writing with a pen in 3D. Then, they can attach any material -- metal, DNA, or tiny "quantum dot" particles -- to the structure. Finally, they shrink the structure to a miniscule size.

"It's a bit like film photography," explained graduate student researcher Daniel Oran. "A latent image is formed by exposing a sensitive material in a gel to light. Then, you can develop that latent image into a real image by attaching another material, silver, afterwards."
