FIELD: biotechnologies.
SUBSTANCE: nanocapillary containing at least two separated channels is introduced into a micro object, with further injection of a substance. Nanocapillary with at least one channel containing electrochemically active material and at least one channel containing injected substance or substance generating it is applied. Substance injection is controlled by measuring electric potential and/or current changes caused by electrochemical reaction in electrochemically active material due to the substance introduction.
EFFECT: enhanced control over substance introduction into micro objects by determining additional informative parameters.
