Quantitative Surface-Enhanced Raman Spectroscopy: Challenges, Strategies, and Prospects
Surface-Enhanced Raman Spectroscopy (SERS) offers high sensitivity and molecular specificity, making it ideal for diagnostics and forensic analysis. However, its widespread adoption has been hindered by challenges in achieving robust, reliable, and quantitative measurements in real-world applications. This article systematically addresses these challenges, presenting strategies from standardized performance metrics (SERS Performance Factor – SPF) to advanced quantification methods (internal standardization, digital SERS) and AI-driven analysis. It highlights how these innovations pave the way for SERS to transition from a specialized technique to a mainstream quantitative analytical tool.
Executive Impact: Transforming SERS for Your Enterprise
This analysis reveals how advancements in quantitative SERS, particularly through new performance factors, digital SERS, and AI-driven data processing, can overcome current limitations to unlock unprecedented sensitivity and reliability. Implementing these strategies can transform SERS into a routine analytical tool across chemical, biological, and medical sciences, leading to significant efficiencies and novel diagnostic capabilities for enterprise applications.

Digital SERS for Single-Molecule Detection
Digital SERS (dCERS) transforms ultra-low concentration detection by redefining measurement from 'signal intensity' to 'binary event count'. This approach leverages statistical analysis (Poisson distribution) of 'on' or 'off' SERS events across mapped areas, allowing quantification at attomolar to femtomolar levels. Ye group's dCERS platform for pharmacokinetic drug detection demonstrates unprecedented sensitivity and robustness.
