Tracers for oil recovery, particularly fluorescent nanotracers comprising polynucleotides such as DNA strands. The tracer comprises a core-shell nanoparticle tailored according to the operation to be traced. It contains a fluorescent core comprising a target polynucleotide that allows the detection thereof in the field and a functionalized polymeric shell that provides increased stability in high salinity aqueous phases. A method for preparing said nanotracer by encapsulation of a polynucleotide.
