Platinum nanoparticle

Platinum nanoparticles are usually in the form of a suspension or colloid of nanoparticles of platinum in a fluid, usually water. A colloid is technically defined as a stable dispersion of particles in a fluid medium (liquid or gas).

Spherical platinum nanoparticles can be made with sizes between about 2 and 100 nanometres (nm), depending on reaction conditions.^[1]^[2] Platinum nanoparticles are suspended in the colloidal solution of brownish-red or black color. Nanoparticles come in wide variety of shapes including spheres, rods, cubes,^[3] and tetrahedra.^[4]

Platinum nanoparticles are the subject of substantial research,^[5]^[6]^[7] with potential applications in a wide variety of areas. These include catalysis,^[7] medicine,^[5] and the synthesis of novel materials with unique properties.^[2]^[6]^[7]
