“…Thus, in the presence of chitosan, the size of the ablated particles was reduced significantly but the size distribution was clearly not affected. This is similar to the results reported by Tsuji et al [11] on silver nanoparticles. Such a size reduction observed here is due to the attachment of chitosan molecules to the surface of the ablated particles preventing them from growth and agglomeration.…”

“…Subsequently, these excited species are ejected and react with each other and with the liquid molecules to form nanoparticles that are supercooled by the surrounding liquid. The technique has been used successfully to generate nanoparticles and nanomaterials by ablating metals and metal oxides in deionized water and solvents [2][3][4][5][6][7][8][9][10][11][12]. In terms of the final product purity, this technique is more advantageous than the chemical one because it can generate stable nanoparticles without the need of using chemical reduction reactions or ion exchange, thus, nanoparticles obtained are free of extraneous ions or other chemicals.…”

“…This technique [6,7] has been used to generate colloids based on metals [8,9], alloys [10,11], ceramics [12], and semiconductors [13] without impurities caused by chemical precursors or preservatives [5] in various liquids. Due to the fact that nanoparticles generated by PLAL are charged, it is possible to functionalize the nanoparticle surface in situ by doping the liquid before laser ablation with surfactants, ligands, monomers, or dissolved polymers, resulting in enhanced colloidal stability and matrix-coupling for polymer nanocomposites [14][15][16].…”

Influence of processing time on nanoparticle generation during picosecond-pulsed fundamental and second harmonic laser ablation of metals in tetrahydrofuran

The influence of fundamental and second harmonic wavelength on ablation efficiency and nanoparticle properties is studied during picosecond laser ablation of silver, zinc, and magnesium in polymer-doped tetrahydrofuran. Laser ablation in stationary liquid involves simultaneously the fabrication of nanoparticles by ablation of the target material and fragmentation of dispersed nanoparticles by post irradiation. The ratio in which the laser pulse energy contributes to these processes depends on laser wavelength and colloidal properties. For plasmon absorbers (silver), using the second harmonic wavelength leads to a decrease of the nanoparticle productivity over process time along with exponential decrease in particle diameter, while using the fundamental wavelength results in a constant ablation rate and linear decrease in particle diameter. For colloids made of materials without plasmon absorption (zinc, magnesium), laser scattering is the colloidal property that limits nanoparticle productivity by Mie-scattering of dispersed nanoparticle clusters.A.

“…Furthermore, this method is a relatively simple way to prepare nanoparticles [26,27] without the need for the removal of unwanted chemicals. With the generation of nanoparticles in deionised water, work has also been reported on preparing noble metal nanoparticles using sodium dodecyl sulphate (SDS) as a surfactant in a colloidal solution [9,10,28,29] and a polyvinylpyrrolidone (PVP) solution [30,31].…”

Silver-titania (Ag-TiO 2 ) nanoparticles with smaller Ag nanoparticles attached to larger TiO 2 nanoparticles were generated by hybrid ultrasonic vibration and picosecond laser ablation of Ag and Ti bulk targets in deionised water, for the first time. The laser has a wavelength of 1064 nm and a pulse duration of 10 ps. It was observed that without the ultrasonic vibration, Ag and TiO 2 nanoparticles did not combine, thus the role of ultrasonic vibration is essential. In addition, colloidal TiO 2 and Ag nanoparticles were generated separately for comparison under the same laser beam characteristics and process conditions. The absorption spectra of colloidal Ag-TiO 2 cluster nanoparticles were examined by UV-Vis spectroscopy, and size distribution was characterised using transmission electron microscopy. The morphology and composition of Ag-TiO 2 nanoparticles were examined using scanning transmission electron microscopy in highangle annular dark field, and energy-dispersive X-ray spectroscopy. The crystalline structures were investigated by X-ray diffraction. The size of larger TiO 2 particles was in the range 30-150 nm, and the smaller-sized Ag nanoparticles attached to the TiO 2 was mainly in the range of 10-15 nm. The yield is more than 50 % with the remaining nanoparticles in the form of uncombined Ag and TiO 2 . The nanoparticles generated had strong antibacterial effects as tested against E. coli. A discussion is given on the role of ultrasonic vibration in the formation of Ag-TiO 2 hybrid nanoparticles by picosecond laser ablation.
