초록/해제  
요약Extracellular vesicles (EVs), particularly exosomes, show significant promise in biomedical diagnostics and therapeutics due to their rich biochemical content. However, precisely characterizing individual exosomes remains challenging for conventional analytical methods. This thesis explores Surface Enhanced Raman Spectroscopy (SERS) combined with advanced machine learning techniques to robustly analyze individual exosomes and provide deeper biochemical insights.The thesis begins by detailing the fundamental principles and physics underlying SERS, emphasizing its sensitivity and specificity for biomolecular diagnostics. It addresses practical considerations in spectral analysis and the challenges involved in accurately interpreting complex, high dimensional SERS data biochemically. The research highlights machine learning integration, particularly neural networks, for effectively overcoming these analytical hurdles. Additionally, the biochemical relevance of SERS signals is explored, where deep learning models were used to predict protein compositions from amino acid SERS profiles.Next, this work focuses on improving on the challenge of the throughput, which significantly restricts the practical application of SERS. This thesis tackles this challenge through innovative approaches, including plasmonic precipitation and surface functionalization strategies. We experimentally validate the potential of this improved platform in clinically relevant scenarios. For instance, early diagnosis of gastric cancer using exosomes derived from tissue and plasma and exploring therapeutic efficacy in ocular treatments using exosomes derived from eyes.This research advances the integration of SERS and machine learning, providing practical pathways toward diagnostic and therapeutic applications.
