An ns Nd:YAG pulsed laser was used to deposit thin films in a vacuum and to generate nanoparticles in the water of Ni, Ti, and NiTi alloys. Laser ablation was measured in terms of removing mass per laser pulse. The laser-generated plasma in vacuum was characterized in terms of temperature and energy of emitted particles. The ablation in water produces nanoparticles with dimensions of the order of 25 nm and solutions with concentrations of the order of some mg/ml. The NiTi alloy stoichiometry is well reported in the deposited thin film and in the composition of the produced nanoparticles. K E Y W O R D S nanoparticles, Ni, NiTi, nitinol, thin films, Ti 1 INTRODUCTION Ni, Ti, and the NiTi alloys have been investigated for many years because of their special chemical and physical properties. Ni is ferromagnetic, corrosion resistant, and applicable as a coating, and it is used in many metallic alloys to confer specific properties. [1] Ti reacts with oxygen, it is mechanically resistant and light, biocompatible, corrosion resistant, and used to realize many alloys. [2] The NiTi alloy shows unique shape-memory and super elastic properties due to its reversible transition between martensitic and austenitic phases depending on the temperature and stress effects. [3] Even though nickel is considered toxic, the nickel-titanium alloy is biocompatible due to the high reactivity of titanium in oxygenated environments and the formation of passivized TiO 2 surface layers; thus, this alloy is used in biomedicine to build orthodontic files, orthopaedic hooks, and many types of prostheses. [4] Our interest in this alloy is derived from its possible applications in the biomedical field for the construction of small orthopaedic prostheses, for interface films between titanium prostheses and other types of supports, and for the possibility of using NiTi nanoparticles for cytotoxicity of Ni in some cell cultures and for their insertion in tumour tissues before adequate radiation therapy with ionizing radiation. These materials are used separately as pure Ni and Ti or together as Ni 55%-Ti 45% atomic stoichiometry, in the shape of bulk, wires, thin films, and-more recently-as nanoparticles. The nanoparticle realization of Ni, Ti, and NiTi is interesting due to the unique properties offered by the large surface-to-volume ratio, which increases with decreasing particle size. Nanoparticles (NPs) based on Ni, Ti, and NiTi are used to study cellular adhesion, Ni toxicity, and Ti biocompatibility and to characterize the chemical and physical NiTi alloy properties by changing their atomic stoichiometry. [5] High interest in synthesizing Ni, Ti, and NiTi nanoparticles came from their potential use in many applications. For example, such NPs can improve the wetting ability of solid surfaces, enhance the interface adhesion, be embedded in polymers to change their optical and electrical properties, be inserted in biological environments, realize molecular markers for nuclear magnetic resonance imaging, and other applications.

This review article highlights the recent advances of the synthesis and application of metal nanoparticles (NPs) fabricated via pulsed laser ablation in liquid (PLAL) phase and also introduces relevant NP formation mechanisms. Although wet-chemical approaches have been well established to synthesize colloidal metal NPs with various components and structures, some inherent drawbacks, such as reaction residuals and/or contaminations, largely limit some of their applications. The PLAL method has recently been developed as an alternative approach and received increasing attention for colloidal NP preparation, without involving complicated chemical reactions. In certain cases, by using PLAL, ligand-free and surface-clean NPs can be obtained and well dispersed in liquid, leading to the formation of a "surface-clean" NP dispersion. This unique feature renders PLAL-synthesised metal NPs attractive candidates for many interesting applications in catalysis, biology, sensing, and clean energy generation and storage. We conclude this review by proposing several interesting research directions and future challenges, from PLAL fabrication to applications. We hope this review can serve as a good reference and help with the further development of PLAL-NPs and their diverse applications.

“…So number of researches have been done to control these parameters through various synthesis methods such as milling, grinding, thermal gas-phase decomposition process, electrochemical etching and chemical methods like sol-gel process. But all of these processes have drawbacks related to the purity and variety of accessible materials [1,2,7]. Under water pulsed laser ablation is an alternative method to address the deficits of the conventional methods as the nanoparticles can be generated from almost any solid material [7,8].…”

Abstract. The great effort that the scientific community has put in the last decade in the study of nanoscience and nanotechnology has been leading the research toward the development of new methodologies of nanostructures synthesis. Among them, Pulsed Laser Ablation in Liquid, PLAL, is gaining an increasing interest thanks to several promising advantages, which include: environmental sustainability, easy experimental set-up (which does not require extreme conditions of the ambient of synthesis), long-lasting stability of the nanoparticles, which are produced completely free of undesired contaminants or dangerous synthesis reactants. In this work, a drop wise flow of deionized water on the periphery of NiTi rotating target was tested as a procedure for the significant production of NiTi nanoparticles. This is a novel technique to improve the ablation efficiency of nanoparticles than the existing techniques of laser ablation. The influence of varying external parameters like laser wavelengths and laser fluences on the size distribution of nanoparticle was investigated. Second harmonic and third harmonics of Nd: YAG nanosecond laser with three different laser fluences of 30 J/cm 2 , 40 J/cm 2 and 50 J/cm 2 was used to ablate the nitinol (Ni-55%, Ti-45%) target. The average particle size and redistribution was characterized by dynamic light scattering (DLS) and the crystalline formation of NiTi nanoparticles were analyzed by X-ray diffraction, where it confirms the alloy formation of NiTi nanoparticles.
