Here we present unequivocal experimental proof that microscale cofactor- and membrane-less, direct electron transfer based enzymatic fuel cells do produce significant amounts of electrical energy in human lachrymal liquid (tears). 100 μm diameter gold wires, covered with 17 nm gold nanoparticles, were used to fashion three-dimensional nanostructured… CONTINUE READING
