Recent progress of surface-enhanced Raman spectroscopy for subcellular compartment analysis.

Understanding subcellular structures is essential for uncovering disease mechanisms. Organelles influence cellular functions and are linked to various disorders. Prior research has shown that disruptions in organelle activity may lead to apoptosis or cancer progression. However, traditional methods often lack the resolution to study these structures in detail. This gap motivated the development of more precise analytical techniques. Surface-enhanced Raman spectroscopy (SERS) offers a non-invasive way to study molecular interactions at the subcellular level. It provides high sensitivity and specificity, making it suitable for cellular investigations. That uncertainty drove the need for a comprehensive review of SERS applications in this field. No prior work had resolved the full potential of SERS in subcellular compartment analysis.

This review aims to summarize recent SERS advancements in subcellular compartment research. It focuses on how SERS can enhance the understanding of organelle functions and disease mechanisms. The study addresses the need for a detailed overview of SERS applications in this area. It explores both labeling and label-free methods for intracellular SERS. The motivation stems from the demand for non-destructive, real-time cellular analysis. SERS is particularly useful for studying drug-targeting strategies and therapeutic mechanisms. The review also highlights the integration of SERS in diagnosis and treatment. It provides a structured perspective on the current state and future directions of SERS in subcellular research.
