“…Indeed, the choice of the hydrophobic block strongly impacts the physico-chemical properties of the resulting self-assembled systems such as the hydrodynamic radius and the critical micelle concentration (CMC) which are two key parameters. Poly(hydroxyalkanoates) (PHAs) and poly(carbonates) (PCs) have attracted considerable attention for the design of drug delivery systems due to their high biocompatibility and low toxicity (Furrer et al, 2008;Wu et al, 2009;Hazer, 2010;Hu et al, 2012;Shrivastav et al, 2013;Chen et al, 2014;Loyer and Cammas-Marion, 2014;Li and Loh, 2015;Nigmatullin et al, 2015). In this context, poly(3-hydroxybutyrate) and poly(trimethylene carbonate) have been developed to produce gels and matrices for tissue engineering (Shishatskaya et al, 2004 ;Asran et al, 2010 ;Song et al, 2011 ;Schüller-Ravoo et al, 2013 ;Rozila et al, 2016 ;Ding et al, 2016 ;Pascu et al, 2016 ;Zant et al, 2016) and NPs for drug delivery (Xiong et al, 2010 ;Jiang et al, 2013 ;Fukushima 2016 ;Pramual et al, 2016).…”
