Researchers in New Jersey have integrated germs with nanomaterials to produce electricity with mushrooms, advanced engineering symbiosis that could lead to biodegradable materials for designers.
The Stevens Institute of Technology team achieved this by covering the white button mushrooms with 3D printed lightning, generating electricity and graphic nanowires that collect current.
Work reported Nano Lettersis part of a wider effort to understand and use cellular biological equipment to create new technologies.
"In this case, our system – this bionic fungus – produces electricity," said Manu Mannoor, assistant professor of engineering at Stevens. "Including galaxies that can produce electricity with nanoscale materials capable of collecting current, we were able to better access the unique properties of both, complement them and create a completely new functional bionic system."
The white button mushrooms absorb rich microbiates, but not particularly blueberries, which Mannoor and post-graduate colleagues Sudeep Joshi suggest, or agaricus bisporus could provide nutrients, moisture, pH and temperature for blueberries to produce electricity for a long time.
Mannoor and Joshi showed that blue-eyed cells for more than a few days, when placed on a white button mushroom cap, compared to silicone and dead mushrooms, used as controls.
"Mushrooms, in essence, serve as a suitable substrate for the environment with enhanced functionality in feeding energy-producing libos," said Joshi. "We first showed that the hybrid system could involve artificial cooperation or engineering symbiosis between two different microbiological kingdoms."
Mannoor and Joshi first printed 3D "electronic ink" containing a graphite nanoribbon to create a branched net that collects electricity.
They then injected "bio-inks" containing stumps into a mushroom cap spiral that intersects with electronic ink. In these places, electrons could be transmitted through conductive graphite nanoribbons through the blue-white outer membranes. The light on mushrooms activates the photosynthesis of flashes by creating a photo.
Mannoor and Joshi, in addition to Blue Bacteria, who lived longer than the symbiosis of engineering paths, showed that the amount of electricity generated by these bacteria may vary depending on the density and alignment with which they are packed: the more densely packaged, the more they produced by Using 3D printing, it was possible to put together them to increase the electricity production activity by eight times.
"Through this work, we can imagine enormous opportunities for next-generation bio-hybrid applications," Mannoor said. "For example, some bacteria can glow, but others feel toxins or produce fuel. By continuously integrating these germs with nanomaterials, we could potentially realize many other amazing design biobihounds for the environment, protection, healthcare and many other areas."
