Described is a process for producing and isolating silver nanocrystals and further heavy metals by a method including a solution having up to 500 mg L-1 of silver ion or other heavy metal using a production system which includes, but not necessarily requires, the feasible germination or the viable growth or the feasible reproduction of seeds or plants, and which uses viable or not viable seeds, seedlings and plants before anthesis or postanthesis. The invention also includes a method for producing nanocrystals from silver or further heavy metals using a saturated or superconcentrated solution of silver ions or other heavy metals, where a monocotyledonous vegetal tissue homogenate obtained from pinching or grinding the vegetative or reproductive structures thereof is introduced into a blade mill, or a roller press or any other milling or homogenization system. Described is a system for recovering nanocrystals from silver or other heavy metals, either from structures or homogenates, fol lowing steps of depression and centrifugation in water and ethanol, alternating with a decantation process until precipitated nanocrystals are obtained and dried at 60 degree C for 25 hours.
