FIELD: diagnostic technique.
SUBSTANCE: sensor element can be used to detect explosives in fingerprints of people, as well as to detect explosives in low concentrations in various (bio)solutions. Sensor element can be used both in laboratories and in situ, for example, in airports, subways, medical institutions, schools, as well as places with large number of people. Sensor element for detecting and identifying explosives in finger washes or fingerprints is represented by hybrid substrates of silicon nanowires decorated with silver and/or gold nanoparticles.
EFFECT: creation of a compact universal sensor for detecting prohibited substances from fingerprints and washes from them, high sensitive capability of the sensor due to the use of nanoparticles of noble metals in the composition of the sensor element and simplifying the process of operating the sensor by security personnel using Raman scattering spectrometer when analysing.
