| Abstract | synthesize capping agents-free metal nanoparticles. 1 LAL involves focused laser pulsed irradiation of a bulk metal target in a liquid and consist of four stages . Laser-matter interaction, plasma induction, cavitation bubble formation and particle release in solution. Strikingly, LAL leads to the formation of very stable “naked” NPs that are long standing for months. It is worth emphasizing that the stabilization of noble metal colloids in water is challenging because of the large Hamaker constant. Noble metal NPs prepared by LAL have a large negative zeta-potential and therefore their stability should be electrostatic in nature and it is due to the presence negative surface charges. The question is what is the origin of these surface charges? |
