These bots were made for walking: Cells power biological machines
Date:11/15/2012

CHAMPAIGN, Ill. They're soft, biocompatible, about 7 millimeters long and, incredibly, able to walk by themselves. Miniature "bio-bots" developed at the University of Illinois are making tracks in synthetic biology.

Designing non-electronic biological machines has been a riddle that scientists at the interface of biology and engineering have struggled to solve. The walking bio-bots demonstrate the Illinois team's ability to forward-engineer functional machines using only hydrogel, heart cells and a 3-D printer.

With an altered design, the bio-bots could be customized for specific applications in medicine, energy or the environment. The research team, led by U. of I. professor Rashid Bashir, published its results in the journal Scientific Reports.

"The idea is that, by being able to design with biological structures, we can harness the power of cells and nature to address challenges facing society," said Bashir, an Abel Bliss Professor of Engineering. "As engineers, we've always built things with hard materials, materials that are very predictable. Yet there are a lot of applications where nature solves a problem in such an elegant way. Can we replicate some of that if we can understand how to put things together with cells?"

The key to the bio-bots' locomotion is asymmetry. Resembling a tiny springboard, each bot has one long, thin leg resting on a stout supporting leg. The thin leg is covered with rat cardiac cells. When the heart cells beat, the long leg pulses, propelling the bio-bot forward.

The team uses a 3-D printing method common in rapid prototyping to make the main body of the bot from hydrogel, a soft gelatin-like polymer. This approach allowed the researchers to explore various conformations and adjust their design for maximum speed. The ease of quickly altering design also will allow them to build and te
