Liposomal systems are well known for playing an important role as drug carriers, presenting several therapeutic applications in different sectors, such as in drug delivery, diagnosis, and in many other academic areas. A novel class of this nanoparticle is the actively target liposome, which is constructed with the surface modified with appropriated molecules (or ligands) to actively bind a target molecule of certain cells, system, or tissue. There are many ways to functionalize these nanostructures, from non-covalent adsorption to covalent bond formation. In this review, we focus on the strategies of modifying liposomes by glycerophospholipid covalent chemical reaction. The approach used in this text summarizes the main reactions and strategies used in phospholipid modification that can be carried out by chemists and researchers from other areas. The knowledge of these methodologies is of great importance for planning new studies using this material and also for manipulating its properties.
