The development of a highly parallel enzyme logic sensing concept employing a novel encoding scheme for the determination of multiple pathophysiological conditions is reported. The new concept multiplexes a contingent of enzyme-based logic gates to yield a distinct 'injury code' corresponding to a unique pathophysiological state as prescribed by a truth(More)
A multi-enzyme biocatalytic cascade processing simultaneously five biomarkers characteristic of traumatic brain injury (TBI) and soft tissue injury (STI) was developed. The system operates as a digital biosensor based on concerted function of 8 Boolean AND logic gates, resulting in the decision about the physiological conditions based on the logic analysis(More)
We report a realization of an associative memory signal/information processing system based on simple enzyme-catalyzed biochemical reactions. Optically detected chemical output is always obtained in response to the triggering input, but the system can also "learn" by association, to later respond to the second input if it is initially applied in combination(More)
The biochemical system logically processing biochemical signals using immune-specific and biocatalytic reactions was designed, and the generated output signals were analyzed by AFM and optical means. Different patterns of immune signals resulted in the formation of various interfacial structures followed by biocatalytic reactions activated by the next set(More)

The development of a screen-printed strip-based amperometric biosensor for the determination of myeloperoxidase (MPO) levels is reported. The biosensor utilizes 3,3',5,5'-tetramethylbenzidine (TMB) as a redox mediator to enable high-sensitivity quantification of physiological levels of MPO. A multivariate parameter optimization was performed. Under the(More)
Computing based on biochemical processes is a newest rapidly developing field of unconventional information and signal processing. In this paper we present results of our research in the field of biochemical computing and summarize the obtained numerical and experimental data for implementations of the standard two-input OR and AND gates with double-sigmoid(More)
