A METHOD OF ATTACHING A CELL-OF-INTEREST TO A MICROTUBE

摘要

A method of attaching a cell or a membrane-coated particle-of-interest to a microtube is provided. The method comprising: co-electrospinning two polymeric solutions through co-axial capillaries, wherein a first polymeric solution of the two polymeric solutions is for forming a shell of the microtube and a second polymeric solution of the two polymeric solutions is for forming a coat over an internal surface of the shell, the first polymeric solution is selected solidifying faster than the second polymeric solution and a solvent of the second polymeric solution is selected incapable of dissolving the first polymeric solution and wherein the second polymeric solution comprises the cell or the membrane-coated particle-of-interest, thereby attaching the cell or the membrane-coated particle-of-interest to the microtube. Also provided are microtubes with attached, entrapped or encapsulated cells or membrane-coated particles and methods of using same.
