Direct metal writing and precise positioning of gold nanoparticles within microfluidic channels for SERS sensing of gaseous analytes

Direct metal writing and precise positioning of gold nanoparticles within microfluidic channels for SERS sensing of gaseous analytes

We demonstrate a one-step precise direct metal writing of well-defined and densely packed gold nanoparticle (AuNP) patterns with tunable physical and optical properties. We achieve this by using two-photon lithography on a Au precursor comprising poly(vinylpyrrolidone) (PVP) and ethylene glycol (EG)...
