Synthesis of nanosized particles during laser ablation of gold in water

Modulatory Effect of Citrate Reduced Gold and Biosynthesized Silver Nanoparticles on α-Amylase Activity

“…The HAucl 4 reduced by citrate reduction showing red wine color after 10 min confirmed the formation of gold nanoparticles and the SPR peak is observed at 510 nm (Figure 2). The absorbance peak around 526 nm with the peak position remaining practically constant also indicates the production of gold nanoparticles [45]. We observed a faint pink coloration of the solution after several pulses of the experiment.…”

Size Control of Gold Nanoparticles Synthesized by Laser Ablation in Liquid Media

“…Numerous investigations have been performed in order to produce metallic NPs with controlled size and functional properties [8][9][10][11]. Variation of laser ablation parameters [9,12] and chemical properties [13][14][15][16] of surrounding liquid media has been the primary focus of these studies.…”

A Review on Synthesis Silver Nano-Particles

“…Silver nanoparticles may be synthesized by optical device ablation of tiny bulk materials in solution (Mafune et al, 2001;Mafune et al, 2000;Kabashin, 2003;Dolgaev et al, 2002;Sylvestre et al, 2004). The ablation potency and also the characteristics of creating nanosilver particles rely upon several factors like the wavelength of the optical device contact the tinny target, the length of the optical device pulses (in the femto-, picoand unit of time regime), the laser fluence, the ablation time length and also the effective liquid medium, with or while not the presence of surfactants (Kim et al, 2005;Link et al, 2000;Kawasaki, 2006;Tarasenko et al, 2006). One vital advantage of the optical device ablation technique compared to alternative strategies for production of metal colloids is that the absence of chemical reagents in solutions.…”
