Novel "Smart" Biofuel Cells, Integrated with Biocomputing Systems, have been Developed by Professor Evgeny Katz and his Research Team
Biofuel cells with switchable power release, controlled by biochemical signals logically processed by biomolecular computing systems, have been designed by Professor Evgeny Katz and his group. The switchable properties of the biofuel cells are based on the polymer-brush-modified electrodes, with the activity dependent on the solution's pH value. The pH changes generated in situ by biocatalytic reactions allowed the reversible activation - inactivation of the bioelectrocatalytic interfaces, thus affecting the activity of the entire biofuel cells. Boolean logic operations performed by either enzymes-or immune-based systems were functionally integrated with the switchable biocatalytic process, allowing for logic control over them. Scaling up the complexity of the biocomputing systems to complex multi-component logic networks (with a built-in "program") resulted in the control of the bioelectronic systems by multi-signal patterns of biochemical inputs. Future implantable biofuel cells, producing electrical power on-demand, depending on physiological conditions are feasible as the result of the present research. See Figure 1. This work represents novel fundamental results in the area of renewable and non-conventional energy systems. The studied biofuel cells exemplify a new kind of bioelectronic devices where the electrical power production is controlled by a biocomputing system. Such devices will provide a new dimension in bioelectronics and biocomputing, benefiting from the integration of both concepts.
Figure 1. The cartoon shows schematically the switchable biofuel cell controlled by pH changes produced in situ by the enzyme logic systems processing biochemical inputs.
CAMP to Sponsor Fifteenth International Symposium on Chemical - Mechanical Planarization
CAMP will sponsor its Fifteenth International Symposium on Chemical-Mechanical Planarization during the month of August. The three-day symposium/workshop will be held (August 8-11, 2010) at the Crowne Plaza Resort & Golf Club in Lake Placid, New York. It will include presentations by industrial and university representatives and a poster session. The co-organizers of this year's International CMP Conference are S.V. Babu (Distinguished University Professor and CAMP Director, Clarkson University), Manabu Tsujimura ( Director and CTO of Ebara Corporation in Japan), Jin-Goo Park ( Professor, Department of Materials Engineering at Hanyang University), Donald Canaperi (Senior Engineer at IBM), Joseph Steigerwald (Intel Fellow; Technology and Manufacturing Group and Director of Chemical Mechanical Polish Technology for Intel Corporation) and Jihong Choi (Senior Process Development Engineer at Global Foundries).
