Abstract: Multi-angle radiographic imaging enables 3D visualization of internal surgical targets like solid-tumors, heart vessels, blocked glands or any bodily cavities like fallopian or Eustachian tubes for diagnostics and surgery planning. Those images are dimensionally precise and easily replicated as life-forms with 3D printing for exact modeling. The “negative” aspects of the images are the diseased tissues requiring excision, as in a solid-tumor example. Needle biopsies are routine and can be radiographically guided. Similarly, guided needle delivery of a magnetic surgical fluid containing fullerenes into a target site, such as a solid tumor is less invasive than laparoscopic techniques. Introducing an external magnetic field force can then be used to propel, rotate and maneuver fullerenes into cellular matter or into tissue.

Abstract: Embodiments of the present disclosure pertain to methods of opening a lipid bilayer by associating the lipid bilayer with a molecule that includes a moving component capable of moving (e.g., rotating) in response to an external stimulus; and exposing the molecule to an external stimulus before, during or after associating the molecule with the lipid bilayer. The exposing causes the moving component of the molecule to move and thereby open the lipid bilayer (e.g., by pore formation). The external stimuli may include an energy source, such as ultraviolet light. The opened lipid bilayer may be a component of cell membranes in vitro or in vivo. The opening of the lipid bilayer may allow for the passage of various materials (e.g., active agents, such as peptide-based drugs) through the lipid bilayer and into cells. Additional embodiments of the present disclosure pertain to the aforementioned molecules for opening lipid bilayers.
