Synthesis of stable silver colloids by laser ablation in water

Effects of Different Laser Pulse Regimes (Nanosecond, Picosecond and Femtosecond) on the Ablation of Materials for Production of Nanoparticles in Liquid Solution

“…There is existing research on laser-material interaction [6][7][8]; however, these show how differently pulsed lasers can be used for material processing, especially in nanotechnology. Furthermore, there are relevant findings concerning laser ablation of nanoparticles in liquid environments [9][10][11][12], and they are somewhat showing the effects of different laser pulse durations on the ablation of nanoparticles. Even most previous research on laser-material interaction and laser-generated nanoparticles tends to highlight laser beam parameters and experimental setups to produce small and well-distributed nanoparticles and to precision material processing, there is little emphasis on the optimal laser parameters to apply in laser material processing.…”

GeO2 Films with Ge-Nanoclusters in Layered Compositions: Structural Modifications with Laser Pulses

“…A method of tissue destruction in malignant tumours is widely known; it employs injection of colloidal solutions containing Ag-NCs with average diameter ~ 5-7 nm into tumor (Tyurnina et al, 2011). Ag-NCs spread over the tumour body and penetrate some part of its cells.…”

“…Therefore, a deposited film of germanium oxides should now not be considered as a fully complete and final result of some process sequence; instead, it should be considered as a material suitable for subsequent modifications. In particular, based on such layers, one can create light-emitting diodes, photodiodes, optoelectronic couples, optical fibers, interference filters, mirrors, lenses, diffraction gratings and holograms, as well as single electron transistors, memory elements, resists for laser and probe nanolithography, low-k and high-k dielectrics, and a component of colloidal solutions of Ge-nanoparticles to fight against cancer in medicine (Tyurnina et al, 2011). To date, not all device applications of germanium oxide layers have been identified.…”

Production of Ultrafine Ag Nanoparticles by Laser Ablation in Diluted Sodium Borohydride Solution and Their Antibacterial Properties

“…Firstly, at a higher fluence, NPs are not only formed by nucleation and growth of particles in a dense plasma cloud during laser ablation but are also formed by the ejection of metal droplets from the target; therefore, increasing the laser fluence leads to an increase in the agglomeration probability because of increment of the melting depth of the target surface and amount of target material simultaneously appeared in liquid [42,43]. where the optical density is related to the bacteria cell survival.…”
