Their cockroach biofuel cell is a bundle of thin carbon wires sealed inside a glass capillary tube. The cell is about 0.05 cm in diameter and a few centimeters long. To make up the cell's anode, Scherson and his team coated the wires with two enzymes: trehalase to break the sugar trehalose into two glucose molecules and glucose oxidase to extract electrons from the glucose. To create the cathode, the researchers coated the wires with the enzyme bilirubin oxidase to shuttle the generated electrons to oxygen to produce water. Because the enzymes alone can't efficiently transfer electrons to and from the electrode, the researchers also added an osmium complex to the carbon wires to act as an electron shuttle. The researchers selected trehalose, says Scherson, because of its high concentration in cockroach blood, 30 mM.

iWorx offers 4-channel (M4) or single-channel (M1) Myograph systems from Radnoti Glass Technology. These systems are designed for researchers performing contractile force studies on small ring samples with sizes ranging from 60 mm to over 1 mm in diameter. Examples include mouse aortic rings and small intestinal ring samples as well as micro-vessel preparations like mesenteric arteries.The Myograph systems include myograph chambers with transducers and amplifiers, a base with sliding wrist rest, temperature controllers, stands, tubing kits and all other essential items to conduct an experiment.iWorx offers a myograph normalization module (LS-20NM) which calculates the optimal pretension settings for each sample prior to conducting an experiment.
