Nanobiology is the branch of science that studies biological phenomena at the nanometer scale. At this scale, researchers investigate the interactions between nanomaterials and living organisms, as well as the development of new materials and devices that can be used in biomedicine and biotechnology. Synonyms for the word nanobiology include nanobiotechnology, nanomedicine, nanobiophysics, and nano-bioengineering. Each of these terms emphasizes different aspects of the field, such as the use of nanotechnology in medicine or the application of physics principles to biological systems. Whatever the term used, nanobiology represents a rapidly growing area of research that could revolutionize the way we diagnose and treat diseases in the future.
