Nanomaterial-based sensors as a volatolomic analytical platform: simplified working mechanisms. These sensors may be used in medical care in future volatolome-based diagnostic devices. Clockwise: optical sensors, colorimetric sensors, surface acoustic wave (SAW) sensors, piezoelectric sensors, metal oxide (MO) sensors, silicon nanowire (SiNW) sensors and monolayer-coated metal nanoparticle (MCMNP) sensors.
