Biofilm monitoring by photoacoustic spectroscopy
Water Science and Technology, 2003 The use of photoacoustic spectroscopy (PAS) as a new biofilm monitoring technique is presented. Growth and detachment of biofilms at three different positions inside a flow channel were monitored by photoacoustic measurements in the visible spectral range (λ = 532 nm).
