20090270266 | Method for Electrocatalytic Protein Detection - The present invention provides a method of detecting an analyte in a sample with probe-modified electrodes and measuring an electrocatalytic signal generated by a binding of an analyte in the sample to a probe. | 10-29-2009 |
20130316340 | SYSTEMS AND METHODS FOR MULTIPLEXED ELECTROCHEMICAL DETECTION - Contemplated methods and devices comprise performing electrochemical sample analysis in a multiplexed electrochemical detector having reduced electrical cross-talk. The electrochemical detector includes electrodes that share a common lead from a plurality of leads. The sample, which may be a liquid sample, is introduced into one or more sample wells and a signal is applied to at least one of the electrodes. A response signal is measured while simultaneously applying a substantially fixed potential to each of a remainder of the plurality of leads. | 11-28-2013 |

20140072962 | SYSTEMS, DEVICES, AND METHODS FOR IDENTIFYING A DISEASE STATE IN A BIOLOGICAL HOST USING INTERNAL CONTROLS - Contemplated methods and devices comprise detecting the presence of a pathogen in a biological host. In certain implementations, a sample is provided from a biological host. A biosensor is provided, the biosensor having a first probe configured to detect a control marker in the sample, the control marker being an endogenous element of the biological host. The biosensor has a second probe configured to detect the presence of a target marker in the sample, the target marker being from a pathogen in the biological host. The sample is applied to the biosensor, and the presence or absence of the control marker in the sample is identified using the first probe. The presence or absence of the target marker in the sample is identified using the second probe. | 03-13-2014 |
20140087375 | BIOPROBES AND METHODS OF USE THEREOF - Disclosed are biomolecule based bioprobes that exhibit improved water solubility and monolayer-forming properties with substantially little or no aggregation that can appreciably interfere with binding of the bioprobes to a target nucleotide. The bioprobes may be used in conjunction with a suitable reporter system to detect very small quantities of biological markers. The bio-probes comprise a nucleobase sequence capable of hybridizing to a target nucleotide; and at least one charged functional group attached to said nucleobase sequence. Also disclosed are biosensors, and sensing devices that comprise the bio-probe. Further disclosed are suitable electrochemical reporter systems for use with bioprobes. Methods of use of these devices and probes, including for the detection of target biomarkers, including biomarkers for cancer cells or pathogens, are also included. | 03-27-2014 |
20140342359 | VERSATILE AND SENSITIVE BIOSENSOR - Contemplated methods and devices comprise use of a charged probe and a neutralizer in the electrochemical detection of a wide range of analytes, including nucleic acids, proteins, and small molecules. In certain embodiments the neutralizer forms a complex with the probe that has a reduced charge magnitude compared to the probe itself, and is displaced from the probe when the complex is exposed to the analyte. | 11-20-2014 |
20150377831 | DIGITAL MICROFLUIDIC DEVICES AND METHODS EMPLOYING INTEGRATED NANOSTRUCTURED ELECTRODEPOSITED ELECTRODES - Digital microfluidic devices, and methods for the control and fabrication thereof, and provided in which an integrated nanostructured electrodeposited electrode is provided such that the digital microfluidic array can be actuated to contact a droplet with the nanostructured electrodeposited electrode. In some embodiments, digital microfluidic devices are provided having an integrated electrochemical sensor, where the working electrode is provided in the form of a nanostructured electrodeposited electrode. Various methods of fabricating such integrated device are described, including methods that employ a lift-off process that exposes an underlying base electrode for the electrodeposition of a nanostructured electrodeposited electrode, while providing a hydrophobic surface for droplet transport. | 12-31-2015 |
