Marziale Milani graduated in Theoretical Physics in 1974 at the State University of Milan, Italy. Professor of Physics since 1992, he worked on radiation–matter interactions, on phase transitions in systems far from equilibrium, biooptoelectronics and electron microscopy with special interest in Focused Ion Beam microscopy and in image analysis. He was responsible of the European Project for Training and Mobility of Researchers (TMR) and coordinated the Summer Schools in Electron Microscopy in the frame of a Project for the Internationalisation of the Iraqi Institutional Scientific Structures.He authored scientific books and publications (more than 200) on laser physics, statistical mechanics, biooptoelectronics, yeast cell response to Soft X rays, and nanoparticles in bacteria.Roberta Curia approached the bacteria-plastic materials interactions during her thesis work in Biological Sciences at the University of Milano-Bicocca, Milan, Italy. Within the collaboration with the Laboratory of Microscopic Anatomy of the N. F. Gamaleya Federal Research Center for Epidemiology & Microbiology of Moscow, Russian Federation, she investigates via electron microscopy the bacterial biodegradative activity against polymeric dental prostheses. Special interest is focused on the acquisition, processing and interpretation of electron microscopy images.Francesco Tatti, born in Rome in 1966, graduated in Hardware Electronics.His career in Electron Microscopy started in 1987 as Field Service Engineer for SEM and EDS systems at Philips Electron Optics in Italy. In late 2005, as part of the FEI Company, he joined the Application Team in Eindhoven, the Netherlands, to support SEM and FIB/SEM customers across Europe and close by countries. In this role he cooperated with some users to publish articles, papers and chapters for books on different topics related to FIB/SEM applications, ranging from Materials Science to Life Sciences.Natalia Vladimirovna Shevlyagina, PhD has a Medical University education.She works at the laboratory of electron microscopy of N. F. Gamaleya Federal Research Center for Epidemiology and Microbiology, Moscow, Russian Federation.The main direction of her research is the behaviour and interaction of different kinds of viruses, bacteria and cell cultures. She has more than 100 scientific articles published in Russian and foreign scientific journals.Besides her scientific research, she works as a practical bacteriologist helping patients identify pathogens and determine antibiotic susceptibility.
