Less than two decades ago aluminium plasmonics emerged and attracted great interest. Aluminium nanoparticles were produced on fused silica substrates by the direct picosecond laser deposition technique. The as prepared active substrates were used for the first time to 355 nm surface-enhanced Raman spectroscopy to detect coconut milk as a probe analyte. The µ-Raman spectrum was also applied for comparison and the transmission spectrum of the aluminium nanoparticles array was checked.
