METHOD OF MANUFACTURING NANOTUBES ARRAYS FOR CELL TRANSFECTION Russian patent published in 2014 - IPC A61M5/00 B82B3/00 

FIELD: chemistry.

SUBSTANCE: in a method of manufacturing a nanotube array for cell transfection a multi-layered film structure with mechanically strained layers is made on a crystal substrate. A contour of a film structure area released from the crystal substrate is formed with respect to a separately taken tube. A released area of the film structure is formed as one containing a portion, intended for the tube formation, and a portion, intended for formation of the curved film element, providing positioning of the tube relative to the crystal substrate. After that, the first of the said portion is released with its transformation into the tube due to mechanical strains, and the second portion, curving due to mechanical strains. The tube positioning relative to the crystal substrate is achieved in the following way: after release of the second portion, curving due to mechanical strains, from connection to the substrate, the Archimedes force is applied in addition to the action of mechanical strains, creating torque forces, trying to curve the film element.

EFFECT: required tube positioning relative to the crystal substrate.
