Link: Gecko-inspired tape sticks to Teflon .
....Unbundled, their nanotube tape was nearly as adhesive as a live gecko, but as these same tubes were clustered into bundles, their strength went up. By the time the authors optimized the combination of fiber length and bundle width, their tape was over four times stronger than a gecko: a square centimeter was sufficient to support nearly four kilograms. Although this was weaker than the initial strength of a standard piece of adhesive tape, the "gecko tape" had staying power. Its adhesive properties remained stable over time, while those of the adhesive tape dropped below those of the gecko tape after about five minutes.
Because of its reliance on van der Waals forces, the gecko tape had some unusual properties. These forces can work between any two surfaces, allowing the tape to stick to Teflon...
