As the Biophysical Society continues to grow, the Society's subgroups allow members to meet and interact within more focused areas in smaller groups. Subgroups hold scientific symposia and business meetings each year on the Saturday that starts the Annual Meeting. They also sponsor several awards, including the Student Research Achievement Awards (SRAA) Poster Competition.

Membership to the Society's subgroups is open to all members. New subgroups may be formed by petition, signed by at least 100 regular members. The petition and accompanying bylaws need to be approved by Council.

Biopolymers in vivo

The purpose of this subgroup is to create a forum to discuss biophysical properties and function of biomolecules in cells and cell-like conditions, and to develop experimental and computational approaches to study these phenomena. The subgroup invites participants from all scientific disciplines with an interest in broadening our understanding of biophysical processes in cells, using approaches ranging from biophysical studies of biomolecules in vitro and in silico to experiments performed in living cells and beyond. We believe that this is a timely and emerging field of high importance for all aspects of biophysics. Although biopolymers such as proteins and nucleic acids are the workhorses of the cell, our knowledge about how they behave in cells is limited. One reason for this shortcoming is that the microenvironments inside cells and in cell membranes (and in extracellular spaces of multi-cellular organisms) are extremely complex, with macromolecules together occupying as much as 40% of volume but with the composition of macromolecules highly heterogeneous and constantly changing.

Article 1

Purpose: The purpose of the Subgroup shall be to advance and disseminate knowledge regarding structural and physical properties, mechanisms, and biological functions of biopolymers in cells and in complex environments.

Article 2

Membership: Members of the Biophysical Society can join the Subgroup; non-members of the Biophysical Society are welcome to participate in Subgroup activities.

Article 3

Dissolution: This group may be dissolved at the discretion of the Council of the Biophysical Society.

Article 4

Meetings: Business meetings shall be held in connection with the annual scientific meeting of the Biophysical Society. Scientific meetings shall be held at the discretion of the Council. These meetings will be held in association with the annual Biophysical Society meetings.

Article 5

Dues: In addition to those requested by the Biophysical Society, dues of $15/year will be levied by the Subgroup Council.

Article 6
