New diverse nanostructures are spontaneously formed from liposomes in solution under the control of an external electric field. A method is shown that can induce the formation of logne range (millimetes) membrane bound nanotubes of characteristic radial diminsions of tens of nanometers. These new structures are of potential use in a vast variety of applications in micro and nanoscale studies and devices. The initial location and attachments can be addressed on a nanometer scale with molecular recognition or other physical interactions. These new observations suggest that unique structures for bionanoengineering may be created and shape and fuction of individual biological membranes and networks of membrane-bound structures are directly influenced by electric fields.
