Extracellular vesicles (EVs), particularly exosomes, play a crucial role in cell-to-cell communication by facilitating the exchange of biological information and materials. EVs are abundantly found in various clinical samples, including blood, urine, saliva, tears, and cerebrospinal fluid. Due to their cargo of diverse biomolecules such as proteins, peptides, lipids, and nucleic acids derived from parent cells, EVs hold great potential as valuable biomarkers for clinical diagnosis and prognosis. In this presentation, I will discuss our research findings on EV isolation techniques, biomarker discovery strategies, detection methods, and translational applications. Firstly, I will introduce the Exosome Total Isolation Chip (EXOTIC) device developed for isolating and identifying EVs from lung cancer patients. This platform enables modular separation and analysis of EV subtypes secreted by different cells along with their respective size distribution. Additionally, I will present the Exosome Detection via the Ultrafast-isolation System (EXODUS) for various applications including characterizing EVs in different biological samples and tracing tissue and cell functions based on urine samples. Next, I plan to introduce iTEARS, which is used to discover the secrets of tear EVs as biomarkers for detecting ocular disorders and systemic diseases. Furthermore, iNEBULA will be discussed for investigating the biological profiles of tear EV subsets with different sizes from healthy individuals and exploring the origins of EV proteins. Finally, I will present the gold nano-dual probe technique (nPES) for quantitative detection of individual plasma exosomes from patients with pancreatic cancer. Simultaneously, a robust acute pancreatitis identification and diagnosis (RAPIDx) method will be demonstrated through proteomic fingerprinting analysis of intact nanoscale EVs from clinical samples. The goal of our work on EVs is to support fundamental research, promote clinical diagnosis, and facilitate the translation of therapeutics.
