text: Because of its ability to cause chemical reactions and excite fluorescence in materials, ultraviolet radiation has a number of applications. The following table gives some uses of specific wavelength bands in the UV spectrum.
  * 13.5 nm: Extreme ultraviolet lithography
  * 30–200 nm: Photoionization, ultraviolet photoelectron spectroscopy, standard integrated circuit manufacture by photolithography
  * 230–365 nm: UV-ID, label tracking, barcodes
  * 230–400 nm: Optical sensors, various instrumentation
  * 240–280 nm: Disinfection, decontamination of surfaces and water (DNA absorption has a peak at 260 nm), germicidal lamps
  * 200–400 nm: Forensic analysis, drug detection
  * 270–360 nm: Protein analysis, DNA sequencing, drug discovery
  * 280–400 nm: Medical imaging of cells
  * 300–320 nm: Light therapy in medicine
  * 300–365 nm: Curing of polymers and printer inks
  * 350–370 nm: Bug zappers (flies are most attracted to light at 365 nm)
