The journal publishes papers in the field of biophysics, which is defined as the study of biological phenomena by using physical methods and concepts. Original papers, reviews and Biophysics letters are published. The primary goal of this journal is to advance the understanding of biological structure and function by application of the principles of physical science, and by presenting the work in a biophysical context.Papers employing a distinctively biophysical approach at all levels of biological organisation will be considered, as will both experimental and theoretical studies. The criteria for acceptance are scientific content, originality and relevance to biological systems of current interest and importance.Principal areas of interest include:- Structure and dynamics of biological macromolecules- Membrane biophysics and ion channels- Cell biophysics and organisation- Macromolecular assemblies- Biophysical methods and instrumentation- Advanced microscopics- System dynamics.
