A microneedle-based SERS sensor for simultaneous detection of pH and uric acid in interstitial fluid

Key Points

• Simultaneous detection of pH and uric acid provides essential data for health monitoring and management.
• The sensor uses Surface-Enhanced Raman Spectroscopy (SERS) to achieve high sensitivity and specificity in interstitial fluid.
• Microneedles allow for minimally invasive collection of samples, promoting user comfort and easier application.
• Enhancements like this sensor could revolutionize how conditions related to acid levels are monitored over time.
