From the site:

Biophysics is a diverse and eclectic field, and consequently difficult to categorize. For the purposes of this summary of educational resources in biophysics, biophysics is divided into three parts or topic areas: molecular structures, biophysical techniques, and biological mechanisms. Each topic area is defined here and an attempt is made to indicate how these areas are interrelated within the field of biophysics. An annotated list of specific resources, available as text files or web sites, for each topic area is then provided on subsequent pages.
