Abstract:
In contrast to colloidal chemistry, pulsed laser ablation in liquids is a physical process that generates nanoparticles e.g. from precious metals or alloys directly in water or organic solvents. Zeta potential values up to -80 mV lead to high stabilities. By optimization of production chambers and fluidics, nanomaterial ablation rates have reached the gram/hour scale. Solid raw materials for laser-based colloid production are 5 to 10 times cheaper than commonly used chemical precursor compounds. Laser-generated nanoparticles are highly pure and possess a large surface activity: the particle surface is not blocked by chemical ligands or rests of reducing agents. This leads to applications in biotechnology, medical technology, and catalysis.
