The invention relates generally to a process for isolating subpopulations of EVs to identify biomarkers useful identifying, determining the progression of, and/or prognosing a disease, including a neurological disease. More particularly, the present invention relates to detection technology of various exosomal biomarkers including proteins, protein modifications, sugars, RNA, DNA, lipids, and metabolites, and combinations thereof.

The analysis method for extracellular vesicles, according to the present invention, uses the size-specific separation ability of size exclusion chromatography and the properties of a probe that specifically binds with extracellular vesicles, and by using same is capable of the rapid and easy analysis of the quantity of extracellular vesicles included in a sample, analysis of the physicochemical properties of the extracellular vesicles, analysis of the kind and quantity of the components included in the extracellular vesicles, and analysis of the binding properties or affinity of the probe with respect to the components of the extracellular vesicles. In addition, using the analysis method of the present invention not only enables accurate analysis of extracellular vesicles in a sample, without a sample purification or pre-processing step, but also enables accurate and simple analysis of the components of extracellular vesicles, according to the kind of probe, and thus can improve the efficiency of diagnosis using extracellular vesicles. Also, analysis of the properties or affinity of the probe can be applied to, for example, extracellular vesicle-specific antibody screening, protein screening and chemical-substance screening.

The present description relates to methods for clinically assessing Parkinson's disease in a subject using protein biomarkers of erythrocyte-derived extracellular vesicles (EEV).

The present invention relates to microfluidic fluidic devices, methods and systems as microfluidic kidney on-chips, e.g. human Proximal Tubule-Chip.

A method for characterizing extracellular vesicles at an individual level is described. It comprises obtaining a sample comprising extracellular vesicles to be characterized and functionalizing the extracellular vesicles with plasmonic nanoparticles or a plasmonic coating. The method further comprises irradiating the individual extracellular vesicles with a laser beam and detecting a surface enhanced Raman spectroscopy signal from said individual extracellular vesicle.

This invention provides methods and kits for improved diagnosis of medically relevant conditions by solution based biochemical testing procedures performed in solutions of test samples. The invention provides a method to substitute the cell based morphological information contained within the cytological and/or histological data of the test sample by molecular information obtainable from the solution, wherein the original test sample is dissolved and thus enables for accurate and reproducible assessment of medically relevant diagnosis from dissolved test samples. The method according to the invention comprises the steps of determining the levels of one or more disease markers associated with the condition to be diagnosed, determining the level of one or more normalization markers suitable to substitute the information related to morphological aspects of the sample, comparing and/or combining the data of the disease and normalization markers, and assessing diagnosis of a medically relevant condition.

A method for detecting extracellular vesicles in a sample, including the following steps: (a) applying the sample to a substrate, (b) adding probes suitable for detection which mark the extracellular vesicles by specific binding to them; and (c) detecting the extracellular vesicles by measuring a specific signal from the probes; wherein step (b) can be performed prior to step (a).
