Applications of High-Sensitivity Detection, Component Analysis, and Vector Construction for Extracellular Vesicles in Cancer Diagnosis and Treatment

Extracellular vesicles (EVs), including exosomes and microvesicles, have emerged as pivotal elements in the realm of intercellular communication, particularly within the context of cancer biology. These nano-sized vesicles are integral to various tumor-related processes such as metastasis, immune evasion, angiogenesis, and drug resistance. They encapsulate a diverse array of biomolecules, including proteins, lipids, RNA, and DNA, which mirror the physiological state of their originating cells, thus positioning them as promising biomarkers for cancer. Despite significant advancements, challenges remain in the precise detection, comprehensive analysis, and effective manipulation of EVs for clinical applications. Recent studies have leveraged cutting-edge technologies like nanoparticle tracking analysis, flow cytometry, and next-generation sequencing to enhance the sensitivity and specificity of EV detection and characterization. However, there is a pressing need for further research to refine these methodologies and explore their potential in clinical settings, particularly in the early detection and treatment of cancer.
