“…In the last two decades, an impressive literature reporting basic and translational research on NPs has led to multiple preclinical/clinical trials and the approval of several formulations by regulatory authorities for diagnosis and therapeutics in oncology [O'Brien et al, 2004 ;Stinchcombe, 2007 ;Anselmo and Mitragotri, 2021 ;Aldosari et al, 2021], gene therapies [Coelho et al, 2013 ;Kristen et al, 2019] and more recently the mRNA vaccines [Dolgin, 2021]. These breakthroughs result from optimized synthesis of macromolecules, improvement of their physicochemical features such as size, porosity, shape and surface properties that play an important role in drug encapsulation and delivery [Raemdonck et al, 2015 ;Topete et al, 2015 ;Stylianopoulos et al, 2015], and the formulation of NPs by microfluidics [Almeida et al, 2024]. Despite these successes, the use of drug delivery nanostructures in clinical protocols is far from being a generalized routine and developments of novel NPs are still required to overcome some biological barriers and limitations to address specific cellular targets such as solid tumors with poor prognosis [Blanco et al, 2015].…”
