FIELD: medicine.
SUBSTANCE: method for making a probe-immobilised carrier for detecting a target substance is offered. There is used a substratum containing a reactive group for immobilisation a probe thereon with performing the stages as follows: (i) application of a liquid drop containing a probe on the substratum; (ii) inactivation of the reactive group being within the area different from that of application on the substratum, and (iii) removal of the unreacted probe in the applied liquid drop.
EFFECT: method allows preventing contamination of a stain with the other stain, preventing nonspecific adsorption to a background area in making a probe-immobilised carrier, and nonspecific adsorption following matrix formation.
