Scientists create "bionic mushrooms": can use bacteria and graphene to generate electricity
According to foreign media reports, will you one day use mushrooms at home to generate electricity? Maybe not, but scientists have created a "bionic mushroom" that can generate electricity, and they may pave the way for a more practical bioelectric power system. The research team at Stephens Institute of Technology in New Jersey, led by Manu Mannorr and Sudeep Joshi, used a charged ink containing graphene nanoribbons to 3D print on top of the mushrooms.
Then they used biological ink containing cyanobacteria to print a spiral pattern on a branch pattern printed on the front with a 3D printer.
After that, scientists irradiated this mushroom with a beam of light to make it photosynthesis, and the electrons generated by it could pass through the outer membrane of the bacteria. At the point where the bio ink and electronic ink intersect, these electrons are transferred to the conductive mesh formed by graphene nanoribbons.
In the end, the system produced about 65 nanoamps. Although this is not enough to drive a device, scientists believe that if you use a group of mushrooms at once, you can light an LED. To this end, researchers are looking for ways to increase the electrical output of mushrooms.
