Radiation Induced Pulverization
Ultrafine particles (50 to 200 nm)of an organic compound can be formed by short pulsed laser beams of nano seconds or femto seconds are used. Organic compounds are suspended in water within a transparent vessel and externally irradiated with a pulsed laser to pulverize the drugs in water. (Kato et al, US Patent 7,815,426; 10/19/2011)
