Peptide nanoporous structures

The bacteriostatic and antibacterial properties are in addition to pH-conditions and the nanostructural entrapping mechanism also related to the surface structure developed of the hydrated biomaterial. The nano-particle/crystal size of hydrates are in the interval 15-40 nm with a nanoporosity size of 1-3 nm. The number of pores per square micrometer is at least 500, preferably > 1000 [9]. The number of nanopores will thus be extremely high, which will affect the possibility of catching and fastening bacteria to the hydrate surface - an analogue to how certain peptides may function as antibacterial material due to a structure with nano-size holes within the structure. This may also provide a long-term antibacterial activity after the initial hydration.
