FIELD : medicine. SUBSTANCE : invention refers to a carrier for drugs, biologically active substances, biological objects used in medicine for diagnostics and treatment in pharmaceutical industry. The carrier represents a material sensitive to external magnetic or electric fields and consisting of magnetic or ferroelectric material filmed with biocompatible thermosensitive, biodegradable polymer and/or dispersed in thermosensitive medium properties of which change with varying temperature relative to that of human body within 15.9 to 42°C. The magnetic or ferroelectric materials are made of substance with great magnetocaloric or electrocaloric component effect 1 to 13 K, have temperature of magnetic or ferroelectric phase transition within temperature range 33 to 37°C, and are chosen from the group including rare-earth, transition and precious metals, their alloys and compounds. EFFECT : invention also concerns methods of controlled drug delivery by means of such carrier with enabling release thereof (regulated desorption) in the preset point. 32 cl, 9 ex
