The new ultraviolet (UV) extinction measurements of carbonaceous nanoparticles in the range from 140 nm to 260 nm are presented. The plasma polymerized hydrocarbon nanoparticles were already proposed as a new astro analogue, which describe the infrared (IR) extinction spectra in an excellent way. We use the same particles to find the possible carrier of the 'mysterious' UV 217.5 nm extinction 'bump' of interstellar media (ISM)
