Photoelectrocatalytic detection of NADH on n-type silicon semiconductors facilitated by carbon nanotube fibers
Melisa del Barrio, Moumita Rana, Juan José Vilatela +3
NADH is a key biomolecule involved in many biocatalytic processes as cofactor and its quantification can be correlated to specific enzymatic activity. Many efforts have been taken…
Towards Biochemical Filter with Sigmoidal Response to pH Changes: Buffered Biocatalytic Signal Transduction
Marcos Pita, Vladimir Privman, Mary A. Arugula +3
We realize a biochemical filtering process by introducing a buffer in a biocatalytic signal-transduction logic system based on the function of an enzyme, esterase. The input, ethyl…
Enzymatic Logic Gates with Noise-Reducing Sigmoid Response
Valber Pedrosa, Dmitriy Melnikov, Marcos Pita +4
Biochemical computing is an emerging field of unconventional computing that attempts to process information with biomolecules and biological objects using digital logic. In this wo…
Enzymatic AND-Gate Based on Electrode-Immobilized Glucose-6-Phosphate Dehydrogenase: Towards Digital Biosensors and Biochemical Logic Systems with Low Noise
Vladimir Privman, Valber Pedrosa, Dmitriy Melnikov +3
Electrode-immobilized glucose-6-phosphate dehydrogenase is used to catalyze an enzymatic reaction which carries out the AND logic gate. This logic function is considered here in th…
Analog Noise Reduction in Enzymatic Logic Gates
Dmitriy Melnikov, Guinevere Strack, Marcos Pita +2
In this work we demonstrate both experimentally and theoretically that the analog noise generation by a single enzymatic logic gate can be dramatically reduced to yield gate operat…
Optimization of Enzymatic Logic Gates and Networks for Noise Reduction and Stability
Mary A. Arugula, Jan Halamek, Evgeny Katz +4
Biochemical computing attempts to process information with biomolecules and biological objects. In this work we review our results on analysis and optimization of single biochemica…
Network Analysis of Biochemical Logic for Noise Reduction and Stability: A System of Three Coupled Enzymatic AND Gates
Vladimir Privman, Mary A. Arugula, Jan Halamek +2
We develop an approach aimed at optimizing the parameters of a network of biochemical logic gates for reduction of the "analog" noise buildup. Experiments for three coupled enzymat…
Optimization of Enzymatic Biochemical Logic for Noise Reduction and Scalability: How Many Biocomputing Gates Can Be Interconnected in a Circuit?
V. Privman, G. Strack, D. Solenov +2
We report an experimental evaluation of the "input-output surface" for a biochemical AND gate. The obtained data are modeled within the rate-equation approach, with the aim to map…
