Multiple-probe diagnostic sensor
First Claim
1. A diagnostic sensor device comprising:
- a plurality of sensor probes in communication with at least one signal-generating device that generates a signal to the sensor probes, wherein each sensor probe comprises a substrate that allows for the transmission of the signal and a partially selective surface, wherein the partially selective surface binds proteins within a biological fluid through multiple, noncovalent and non-specific interactions, and wherein the partially selective surface of each sensor probe partitions the proteins within the biological fluid in a different manner;
a means for detecting the signals, the detection means in communication with the plurality of sensor probes and detecting the signals after signal interaction with each partially selective surface; and
a means for analyzing the signals from each partially selective surface by multivariate analysis, the analyzing means in communication with the detection means.

Abstract
There is disclosed a diagnostic sensor device comprising a plurality of sensor probes, a detection device, and a computer for analyzing the signals generated from each sensor probe by multivariate statistical analysis. The plurality of sensor probes comprise a substrate that allows transmission of a signal and a partially selective surface coating the substrate wherein the partially selective surface binds proteins from a biological fluid by multiple, noncovalent interactions, and with the proviso that the partially selective surfaces of each sensor probe in the diagnostic sensor device be different. The diagnostic sensor device can be used as a method for diagnosing disease states in humans and animals, wherein the disease states are characterized by altered protein character and behavior of a biological fluid.
