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)...
