Abstract: The present invention regards nano surfaces and particularly a gradient based nano surface. According to embodiments of the invention a surface bound gradient is created by distributed nanoparticles along a plane surface. This procedure greatly reduces the number of prepared surfaces needed, as well as the methodological error of analysis of adsorption and adhesion phenomena.

Abstract: There is provided a polymeric film adapted to be applied to a surface intended to be submerged, such as a boat hull surface, wherein abamectin is embedded in the film and the concentration of abamectin in the film is 0.01-1% by weight.

Abstract: The proteins involved in barnacle are useful in devising high-strength protein-based adhesives capable of curing under water, coatings for prosthetic implants to serve as an interface between the prosthetic and the bone or other tissue, and methods of preventing biofouling of underwater surfaces. DNA and amino acid sequences of the adhesion proteins are provided and isolated nucleic acid sequences and isolated proteins, vectors comprising such isolated nucleic acid sequences as well as microorganisms comprising such vectors and capable of expressing a barnacle adhesive protein are also provided.
