FIELD: chemistry.
SUBSTANCE: invention relates to a method of making a sensor for obtaining giant Raman scattering spectra, which is a glass capillary whose inner wall is coated with silver nanoparticles. The silver nanoparticles are obtained and attached to the glass surface via reduction of silver ions with alkylamines. The glass capillaries are washed with a detergent solution for optical devices, distilled water while mixing with ultrasound, absolute ethanol and dried in air, placed in a teflon vessel with a reaction mixture of 1 mmol/l AgNO3 and 1 mmol/l alkylamine in ethanol; the reaction mixture is heated at 45-50°C for 40 min with intense agitation along the axis of the capillaries. After the reduction reaction, the capillaries are washed with ethanol and cleaned on the outside.
EFFECT: invention enables to obtain a high-resolution giant Raman scattering sensor.
