“…Such features are very appealing for delivering drugs by different routes and multipurpose clinical approaches [ 4 , 13 , 14 , 15 ]. Size, surface charge and morphology of PNs can be tailored on demand to produce solid capsules/nanoparticles, amphiphilic structures (micelles), and hyperbranched structures (dendrimers), and vesicles [ 16 , 17 , 18 , 19 , 20 , 21 , 22 ], which sizes can usually be smaller than 100 nm but eventually reach hundreds of nm, depending upon the active ingredient or drug, the type and length of the polymer and the preparation method [ 23 , 24 , 25 ]. Besides, the polymers can be chemically modified to encapsulate, adsorb, disperse, or bound the drug [ 14 , 19 , 21 , 26 , 27 , 28 ].…”
