The present invention relates to methods for adhering tissue surfaces and materials and biomedical uses thereof. In particular the present invention relates to a method for adhering a first tissue surface to a second tissue surface in a subject in need thereof, comprising the steps of adsorbing a layer of nanoparticles on at least one of the tissue surfaces, and approximating the surfaces for a time sufficient for allowing the surfaces to adhere to each other. The present invention also relates to a method for adhering a material to a biological tissue in a subject in need thereof, comprising the steps of adsorbing a layer of nanoparticles on the surface of the material and/or the biological tissue and approximating the material and the biological tissue for a time sufficient for allowing the material and the biological tissue to adhere to each other.
