Abstract
A method of producing microparticles including: (a) providing a system including: (i) a vessel containing a liquid; (ii) at least a first pair of electrodes; (iii) a mechanism for igniting an electrical arc between the electrodes; (b) disposing the first pair of electrodes within the liquid, and (c) effecting at least one pulsed electrical discharge between the electrodes so as to produce a plasma bubble, and to produce the microparticles, the microparticles being associated with the plasma bubble, wherein the pulsed electrical discharge has a pulse duration of less than 1000 microseconds, and wherein the pulsed electrical discharge has a current amplitude of at least 1 ampere (A).
