Fabrication of surface-enhanced Raman spectroscopy substrates using silver nanoparticles produced by laser ablation in liquids

Surface ligand modified silver nanoparticles-based SERS sensing platform for ultrasensitive detection of the pesticide thiram in green tea leaves: roles of coating agents in sensing performance

“…Many kinds of AgNPs have been designed and developed as SERS substrates, using physical and chemical synthesis methods. 8–11 For example, Singh's group has fabricated Ag zigzag and Ag nanorod arrays using a glancing angle deposition technique to promote EM enhancement of SERS signal. 10,12 However, the physical synthesis of AgNPs requires extreme conditions and expensive equipment.…”

Magneto-Plasmonic Nanoparticles Generated by Laser Ablation of Layered Fe/Au and Fe/Au/Fe Composite Films for SERS Application

“…Laser ablation is a method for producing nanoparticles, nanowires, quantum dots, and core-shell nanoparticles [18][19][20][21]. Laser can be used to form nanoparticles by melting thin metal coatings or targets [19,20,22], ablation of metal granules [23], forming noble metal surfaces [24], or Si substrates that could later be covered with SERS active metal [25,26]. During the ablation process in gas, nanoparticles are created by the nucleation and growth of laser-evaporated species in a background gas.…”

“…Ablated nanoparticles or surface structures could later be decorated with chemically synthesized structures [24,37,38] or could be used as reductors of metal salts [22,39]. The produced nanoparticles were applied for rat blood analysis [23], detection of explosives [22,24,40], pyrromethene [41], antibiotics [26], pesticides [24,36,39], and many other molecules [38].…”
