2019 Morley Address:
BIOROBOTICS: An Emerging Field at the Boundary between Biology, Chemistry, and Engineering
By Dr. Daniel A. Scherson, Frank Hovorka Professor of Chemistry, and Director of the Ernest B. Yeager Center for Electrochemical Sciences, Case Western Reserve University
Over the last two decades ingenious devices have been developed for converting chemicals present in biofluids into electrical energy in living organisms with potential application in a variety of areas of fundamental and practical relevance.Efforts in our laboratories have focused on the development of such biofuel cells that could be implanted into insects and provide the power required not only for the operation of electronics for sensing, information storage and wireless communication, but also for the stimulation of the nervous system, a strategy that will ultimately allow control of certain aspects of the insect behavior. An attractive feature of this approach is that it provides a continuous and autonomous source of power, thereby avoiding the need for an external battery as implemented recently by other groups who succeeded in controlling wirelessly the path of motion of a cockroach. To this end, we designed, constructed and successfully tested an implantable biofuel cell incorporating a bienzymatic anode capable of dissociating trehalose, a dissacharide found at concentrations of up to tens of mM in the hemolymph of insects, to yield glucose, which is then oxidized to gluconolactone by the enzyme glucose oxidase. As shown recently in our laboratories, this type of biofuel cell can generate up to 15.6 μW/cm2 when implanted in a live cockroach and power a transmitter attached to its body capable of sending radio signals wirelessly to a distant receiver.
Currently, Daniel Alberto Scherson is the Frank Hovorka Professor of Chemistry, and Director of the Ernest B. Yeager Center for Electrochemical Sciences, Case Western Reserve University. Professor Scherson earned his initial degree from the University of Chile. He went on to the University of California, Davis to earn his Ph.D. he did post-doctoral fellowships at UC Berkeley, Lawrence Berkeley Laboratory and Case Western Reserve University. He has been a faculty member at Case Western Reserve University since 1983. His research has focused on experimental and theoretical aspects of electrocatalysis, in-situ and ex-situ spectroscopic techniques for the study of solid-liquid interfaces and the electrochemistry of single crystal metals and supported clusters. He has authored more than 250 papers and holds 10 patents. Dr. Scherson has been awarded the Vittorio de Nora - Diamond Shamrock Postdoctoral Fellowship (1981), a Max Planck Gesellschaft Fellowship (1982-83), the IBM Faculty Development Award (1983-85), a Japan Society for the Promotion of Science Fellowship (1993-94), David C. Grahame Award of the Physical Electrochemistry Division of ECS (2000), Alexander von Humboldt Senior Fellowship Award (2002), Faraday Medal of the Electrochemistry Groups of the Royal Chemical Society (2004), Japan Society for the Promotion of Science Travel Fellowship (2007), Fellow of the Electrochemical Society (2007) and has been Chair of the Gordon Conference in Electrochemistry (2012). Dr. Scherson has also been active in the leadership of the Electrochemical Society, as well as the Cleveland American Chemical Society.
About the Morley Medal :
The Cleveland Section annually sponsors a regional award, which consists of the Morley Medal and an honorarium of $2,000. The next presentation of the Morley Medal will take place at the meeting of the Cleveland Section ACS in May 2017. The award is presented at a banquet, at which time the recipient will deliver the Edward W. Morley Lecture for that year. Travel expenses for the medalist and spouse will be provided.
The purpose of the award is to recognize significant contributions to chemistry through achievements in research, teaching, engineering, research administration and public service, outstanding service to humanity, or to industrial progress.
The area of eligibility includes those parts of the United States and Canada within about 250 miles of Cleveland. The contributions for which the award is given should have been made by the awardee when a resident of this area, or if a major contribution was made elsewhere, the nominee should have continued to make contributions while a resident of this area. Nominations may be made by any member of the American Chemical Society, The Chemical Society or the Chemical Institute of Canada.
