About Publication

Marine biofouling refers to the undesirable growth and adhesion of marine organisms such as barnacles, macroalgae, and microbial slimes on immersed structures. Biofouling composition is determined by collecting samples from marine structures and vessels and analyzing them in laboratories. Alternatively, an approach of online sensing based on Laser-Induced Breakdown Spectroscopy (LIBS), which consists of an analysis of the spectral emission from laser-induced plasma, can be considered for the elemental composition of biofouling. The study of marine biofouling using LIBS has not been attempted previously. In the present work, a laboratory-scale LIBS technique is used to analyze biofouling samples and its constituent common water-borne algae and bacterial species. First, the LIBS database is created under controlled conditions for the selected biofilm constituent algae.
