20130065257 | ENZYME-LOGIC BIOSENSING - Techniques, apparatus and systems are disclosed for implementing enzyme-logic based diagnosis that uses patterns of multiple markers and biochemical processing of the signal information for reliably identifying cardiac abnormalities and providing a final digital binary answer. In one aspect, a biochemical logic sensing system includes a network of enzyme-biocatalyzed logic gates adapted to receive biomarker input signals and perform an enzyme-biocatalyzed reaction resembling a Boolean logic operation using the received biomarker input signals to generate an output signal of the enzyme-biocatalyzed reaction. A signal processing unit is connected to the network of enzyme-biocatalyzed logic gates. The signal processing unit processes the generated output signal of the enzyme-biocatalyzed reaction and generates a digital binary output having a value of zero or one. The generated digital binary output indicates a type of an injury. | 03-14-2013 |
