Surface-enhanced Raman spectroscopy investigation of PO3- (4) to Ag/Al2O3 nanopatterned substrates binding and its dynamics for sensitive detection of phosphate in water
Original language description
We provide fast and sensitive detection of phosphate dissolved in water usingRaman spectroscopy. To this end, phosphate-scavenging planar core/shellsurface-enhanced Raman spectroscopy (SERS) probes consisting of Al2O3-capped Ag nanopatterned sapphire substrate were prepared and optimized.Thanks to scavenging, the probes provide enhancement sufficient to readilydetect phosphate at levels occurring in water sources. In particular, the SERSprobes were successfully tested for selective detection of all phosphate ionsand down to 1μM phosphate concentration (30μg/L of phosphorus in thesolution). The novelty of our contribution lies in real-time SERS monitoring ofthe phosphate Raman markers, which allowed to study the dynamics of phos-phate interaction with the nano-structured surface of the probes. Under natu-ral conditions (neutral to basic environment), the phosphates adsorb on theprobes in form of PO3- (4)in two steps.
