Abstract: The invention relates to a relates to a highly sensitive, non-invasive diagnostic method for detection infectious diseases. In one embodiment, the invention relates to novel rapid, self-working, visual field test for a panel of disease specific derived biomarkers. In one embodiment, the invention comprises a collecting device comprising a collapsible non hygroscopic net tethered with immobilized nanoparticles to capture and concentrate a target analyte present in a fluid; wherein the nanoparticle comprises a core and a shell, wherein the core comprises a molecular bait. The invention also relates to identification of biomarkers for identification of various pathogenic diseases.

Abstract: A collapsible sample collection device with a novel, collapsible 3D capture open affinity net dispersed throughout the volume of the container, said net with tethered affinity moieties, is designed to address the need for low-cost, simple harvesting and concentration of diagnostic analytes that generally does not require any ancillary equipment. The collection device generally permits analytes of interest to be efficiently harvested from body fluid samples, in one step, concentrated, collapsed into a flat mailing size, and protected from degradation without the need for traditional cold chain technologies. The concentration factor will increase sensitivity by several orders of magnitude when coupled with any type of downstream analyte measurement, including point of care testing. The collection device, in various embodiments, obviates the need for handling transport or storage of the fluid portion of the body fluid sample (e.g. blood, urine, saliva, etc.

Abstract: A device and system for conducting accurate diagnosis of states of disease or health, including cancer, with high sensitivity and specificity is described. The system employs a portable cassette-based testing system which is configured to detect pp analytes captured by hydrogel particles equipped with affinity bait(s) and an amplification reporter system. The affinity baits bind to a wide range of analytes, including: metabolites, proteins, nucleic acids, lipids, hormones, cytokines, growth factors, biomarkers, virus particles, exosomes, bacteria, fungi, drug compounds, synthetic organic compounds, volatile odorants, toxicants, and pollutants. The affinity baits bind with extremely high affinity, preserving the captured analyte. This system can increase the sensitivity of detection of said analytes up to ten-thousand-fold.
