Biology on the Nanoscale

Nanoscience plays an important role in the study of biological phenomena because the size of inorganic nanoparticles as probes and the spatial resolution of nanotools match the sizes of macromolecular components employed in living systems. Proteins, nucleic acid fragments, and their supramolecular complexes involved in the DNA replication and transcription, and the ribosome, have typical dimensions in the range of 2–200 nm.
