text: Yo, check it out, UV light's on the scene
  With photocatalysts like titanium dioxide and silver, mean
  They're out here disinfecting water and surfaces
  But UV wavelength's effect on spores, we gotta address
  
  Bacillus spores, they put 'em to the test
  Using different UV wavelengths, they did their best
  TiO(2) and TiO(2)/Ag composites in the mix
  UVA disinfecting Bacillus anthracis and Bacillus brevis, tricks
  
  But spores didn't really feel the same way
  UVB and UVC got 'em in dismay
  B. brevis spores feeling more sensitive, it's true
  To UVB and UVC compared to B. atrophaeus, who knew?
  
  Photocatalytic sterilization, let me break it down
  UVC and UVB, they wear the crown
  UVA, ain't as strong, it's the weakest link
  But TiO(2) in the mix, that's how they disinfect, think
  
  TiO(2)/Ag with UVA, they team up tight
  Sterilizing vegetative cells, taking flight
  TiO(2) and UVC, they're effective against spores
  Inactivation of Bacillus spores, they even the scores
  
  TiO(2) presence, it significantly increased the rate
  Of spore inactivation, can't debate
  Ag ain't too far behind, they hold their own
  When it comes to Bacillus spores, they're fully grown
  
  So remember, if you want sterilization complete
  TiO(2)/Ag with UVA, that's the beat
  And for spores, TiO(2) with UVC's the way
  Disinfection on point, keeping germs at bay
