Various time-resolved spectroscopies that take advantage of surface-enhancement have been developed. Only the most robust substrates can withstand the high-intensity laser pulses used by time-resolved methods. We present a simple and reliable stabilization procedure that uses polyvinyl alcohol for the formation of robust gold nanoparticle oligomers that can withstand different hydration and temperature levels. This procedure can be used to produce oligomers with varying and reproducible plasmon resonance conditions. Results show that gold nanoparticle oligomers stabilized in this way are sufficiently sturdy to be used in 3D printing, opening the door for easy production and integration of plasmonic substrates.
