In this talk I will present some recent results on the synthesis of nanostructured glasses and gelatins prepared by laser ablation in non-conventional liquids. This can be achieved by combining the sol-gel and the laser ablation simultaneously [1]. The results will involve mainly Au nanoparticles but the same idea can be applied to a broad variety of elements and compounds. For the glasses tetraetilorthosilicate (TEOS) and water with hydrochloric acid as a catalyzer are used to produce the starting before ablation. Commercial neutral gelatin powder and hot water were employed to synthesize the gelatins. A Nd:YAG laser emitting at 1064 nm, with an energy of 100 mJ at 10 Hz repetition rate focused on a 2mm diameter laser spot, in the nanosecond range, was the souce to perform laser ablation. The Au target was covered in a vessel in the corresponding liquid. After gelation the glasses and gelatins were dried. The gelatins dry in a few days. For the glasses the drying process can take several months. The obtained samples were characterized by optical absorption and TEM and AFM microscopies. Some applications will be also discussed.
