    Nanoparticles - what they are, how they are made

    Nanoparticles are materials that are confined to the nanoscale in all three dimensions. Engineered nanoparticles play an important role in nanotechnology. The specific properties of nanoparticles is defined by particle size, chemical composition, crystallinity and shape. During production these can be controlled by temperature, pH-value, concentration, chemical
