Specimens prepared for a scanning tunneling microscope (STM) require a very clean and atomically smooth surface. They are frequently placed on mica coated with Au(111), and toluene vapor is commonly used as a chemical fixative.

A scanning tunneling microscope (STM) is a type of scanning probe microscope that functions by passing a probe horizontally at a constant distance just above the specimen while measuring the intensity of the current. This technique can map the surface structure at the atomic level. STM is most effective on conducting materials, but it can also be used to examine organic materials, such as DNA, if they are fixed onto a surface.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.
