Papers dealing with the study of biological phenomena by using physical methods and concepts are welcome for this topic. Biophysics' primary goal 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. 

Some important topics:

Bioenergetics 
Biophysical Theory and Modeling 
Cell Biophysics 
Channels, Receptors and Transporters 
Electrophysiology 
Membranes 
Nucleic Acids 
Photobiophysics 
Proteins 
Spectroscopy, Imaging, Other Techniques 
Supramolecular Assemblies 
Structure and dynamics of biological macromolecules
Macromolecular assemblies
Biophysical methods and instrumentation 
Advanced microscopics 
System dynamics

Accepted papers will be published in a special issue of Physica Sripta, although publication in other of the Journals can be considered if the topic is appropiate.
