FIELD: nanotechnology.
SUBSTANCE: invention relates to nanotechnology, specifically nanotechnology of interactive interaction, sensors or actuation, for example quantum dots as biomarkers. Described is a method of producing colloidal semiconductor quantum dots of zinc selenide, based on reaction of zinc chloride with selenide-ions in presence of ammonia and a coating agent, wherein zinc chloride, distributed in aqueous solution of lactose, used as a coating agent, reacts with selenide ions formed from a solution of sodium selenosulphide, while stirring for one hour.
EFFECT: technically simple, cheap, non-toxic, low-temperature method of producing semiconductor quantum dots of zinc selenide coated with lactose, for use as biological markers.
