Method and system for the detection of cardiac risk factors
First Claim
1. A system for detecting cardiovascular risk factor analytes in a fluid, comprising:
- a light source;
a sensor array, the sensor array comprising a supporting member comprising a plurality of cavities formed within the supporting member;
a plurality of particles, wherein an individual particle is positioned within an individual cavity and is configured to produce a signal in the presence of a cardiovascular risk factor, wherein the cardiovascular risk factor comprises C-reactive protein, high density lipoprotein, low density lipoprotein, very low density lipoprotein, cholesterol, interleukin-6, intercellular adhesion molecule-1, fibrinogen, homocysteine, folate, calcium, lipoprotein a, apolipoprotein A-1, apolipoprotein B, Helicobacter pylori, chlamydia pneumoniae, Herpes virus hominis, and cytomegalovirus; and
a detector, wherein the detector is configured to detect the signal produced by the particles during use.

Abstract
A system for the rapid characterization of multi-cardiovascular risk factor analyte fluids, in one embodiment, includes a light source, a sensor array, and a detector. The sensor array is formed from a supporting member, in which a plurality of cavities may be formed. A series of chemically sensitive particles, in one embodiment, are positioned within the cavities. The particles may produce a signal when a receptor, coupled to the particle, interacts with the cardiovascular risk factor analyte and the particle-analyte complex is visualized using a visualization reagent. Using pattern recognition techniques, the analytes within a multi-analyte fluid may be characterized. In an embodiment, each cavity of the plurality of cavities is designed to capture and contain a specific size particle. Flexible projections may be positioned over each of the cavities to provide retention of the particles in the cavities.
