“…Antibacterial agents play an important and in uential role in various industries such as medicine, textile industry, food industry and also for disinfecting water [1][2][3]. Recently, metal NPshave shown unique properties in different industries and medical processes.High speci c surface areaand the uniform distribution of NPs has provided them widely applications [4].Antibacterial metal nanoparticles have an effect on both grampositive and gram-negative bacteria and cause them through various proposed mechanisms such as reactive oxygenSpecies (ROS), membrane processes and the entry of nanoparticles into the bacteria, the release of ionic metals or direct destruction of bacterial membranes [5][6][7]. Among the metal NPs, IONPsand ZONPshave attracted the attention of researchers due to their high antibacterial properties and cost-effectiveness [8].…”

“…Among the metal NPs, IONPsand ZONPshave attracted the attention of researchers due to their high antibacterial properties and cost-effectiveness [8]. There are several cost-effective methods to synthesize IONPs and ZONPs; Such as sol-gel [9], micro-emulsion [10], Thermal Decomposition [11], chemical precipitation [12], electrochemical [13], electrical arc discharge [14] and electrical wire explosion [15].The electrical discharge method is performed in liquid or gaseous medium, which has been considered by researchers because of its cost-effectiveness and eco-friendly compared to other methods [4,16]. Metallic wireevaporates by high voltage or current intensity.…”

“…The NPs are then nucleated by cooling in a liquid or gaseous medium. With this method, it is possible to produce high purity metal NPs, oxide nanoparticles as well as composite NPs [4,14,15].The properties and nature of nanoparticles synthesized by electrical discharge method depend on factors such as synthesis environment, wire diameter, nature of wire metal, geometric shape of wire, parameters related to electric current and applied voltage and other things [17,18].Environmental parameters such as pressure, pH, surfactant addition and temperature greatly in uence the properties of the synthesized NPs [19,20].…”

Antibacterial performance of nanosecond laser irradiated zirconium-based bulk metallic glass

“…A high Cu/Ni ion release rate and high ROS levels in PBS would be more deadly for S. aureus , thus leading to a better antibacterial performance. Furthermore, the antibacterial properties of Cu, Ni, and ROS may also inhibit cell viability [45][46][47][48].These element would also destroy the membrane structure of cell and induced stimulation on adjacent tissue cell [49][50][51].Herein, a fully crystallized surface led to more serious cell toxicity than the polished and partially crystallized surface (Fig. 7).…”
