Laser induced breakdown spectroscopy is potent tool used to explain the interaction of laser with the material of all type and variety fom bulk material to Nano mater and bacteria by analyzing the consequent plasma emission of the specimen by analysis its emission spectrum. In these works we focused on synthesis of nanomaterial and studied the effect of MgO- NPS as an anti - bacterial agent. later we diagnosed the emission spectrum generated by the interaction of laser and the particular bacteria were Staphylococcus aureus and Escherichia coli. Software cycles called spectra-laser were used to scan libs spectra. The spectra of the glass substrate LIBS as well as those of the microorganisms were compared. There was Fe, Magnesium, Na, K, Ca P, S, calcium, and aluminum, Manganese, Copper Carbon, Hydrogen and CN-band in bacterial samples. Escherichia coli and Staphylococcus aureus revealed two lines of carbon 193.02 nm and 247.88 nm and a single H line with ratio of 656.28 nm1.53 and 1.9, 1.83uratively to the amount ratio of 656.28 nm Carbon and hydrogen are the most important components that bacteria and other cancer cells that constitute the bio-samples are composed of. The findings indicated the importance of LIBS in identification and differentiating between different types of bacteria.
