AB  - In the present study, the biological effect of TiO2 nanoparticles on 
      cyanobacteria cells was studied using Microcystis aeruginosa (M. aeruginosa) as a 
      model. Nano-TiO2 as a photo-catalysts agent used for water treatment may pose a 
      risk to ecosystems, especially for the water organisms such as cyanobacteria. 
      Scanning electron microscope (SEM) images provided that with the increasing of 
      photocatalytic time, slime layer on the cell surface was damaged and sunk. 
      Attenuated total reflectance fourier transform infrared (ATR-FTIR) spectroscopy 
      revealed that the vibration peaks of C-C, C-H, C=O, P=O weakened within 12 h. 
      According to the dynamic analysis of the infrared peaks, the damage on the cell 
      groups under nano-TiO2 photocatalysis with different time periods was analyzed. 
      The concentrations of K(+), Ca(2+), Mg(2+) released from the cells were measured, 
      which indicated that nano-TiO2 photocatalysis have changed the cell membrane 
      permeability and fluidity of M. aeruginosa.
