A low‐temperature fusion method for preparing polymeric nanostructures based on low‐pressure CO 2 ‐enhanced chain mobility at the nanoscale is presented. Characterization of the structures reveals a pressure‐tunable rubbery layer on the surface. The successful fusion of polymeric nanostructures (see figure) at temperatures below the bulk glass‐transition temperature of the polymer is demonstrated. The technique has potential for the assembly of 3D micro/nanoscale polymeric devices for biomedical applications.
