Abstract

This invention provides novel nanofibers and nanofiber structures which posses adherent properties, as well as the use of such nanofibers and nanofiber comprising structures in the coupling and/or joining together of articles or material.

Claims

1. A hemostat including a substrate having at least a first surface and a first plurality of inorganic nanofibers comprising silicon or silicon oxide deposited on the first surface, wherein the plurality of nanofibers have a curved or curled configuration for contacting with a second surface at two or more contact points on each of said nanofibers, wherein the contacting adheres the first surface to the second surface substantially by van der Waals forces between the nanofibers and the second surface.

2. The hemostat of claim 1, wherein the nanofibers comprise hollow nanotubular structures.

3. The hemostat of claim 1, wherein the first surface further comprises a second plurality of inorganic nanofibers deposited on the first surface, wherein the second plurality of nanofibers have a straight configuration.

4. The hemostat of claim 1, wherein the nanofibers comprise silicon nanowires.

5. The hemostat of claim 1, wherein the second surface comprises a tissue surface.

6. The hemostat of claim 1, wherein the second surface comprises an artery.
