A method of producing a microtube is provided. The method comprising co-electrospinning two polymeric solutions through co-axial capillaries to thereby produce the microtube, 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. Also provided are electrospun microtubes.

Method of producing a microtube

Provided are methods of petroleum sequestration, which use electrospun microtubes capable of sequestering the petroleum from the water, and method of depleting and optionally degrading petroleum from water using floating devices which comprise the electrospun microtube attached to a floating carrier.

Methods for adsorption and biodegradation of petroleum

Provided is a method of attaching a molecule-of-interest to a microtube, by 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 molecule-of-interest, thereby attaching the molecule-of-interest to the microtube. Also provided is an electrospun microtube comprising an electrospun shell, an electrospun coat over an internal surface of the shell and a molecule-of-interest attached to the microtube.

Methods of attaching a molecule-of-interest to a microtube

Provided are method of generating a fiber from a globular protein such as albumin. Also provided are albumin fibers and fabrics and methods of using same for bonding a damaged tissue or for ex vivo or in vivo formation of a tissue.
