Femtosecond laser induced plasmon assisted processing novel SERS substrate integrated microfluidic sensor for trace Pb2+ and Cd2+ in seawater

Key Points

• Trace detection of lead and cadmium ions is achieved using a novel microfluidic sensor design.
• Sensitivity is enhanced by incorporating a femtosecond laser-induced plasmon substrate, improving detection limits.
• The innovative approach integrates surface-enhanced Raman scattering (SERS) for accurate ion quantification.
• This method highlights potential applications in environmental monitoring of seawater contamination.
