• performed to prevent complement system activation. However, the effect of this process on protein corona formation and, in turn, LNP functionality is unclear. Here, we investigated the effects of serum heat inactivation on protein corona formation on LNPs containing D-lin-MC3-DMA (MC3) or C12-200 (C12

• subsequent cell-nanoparticle interactions remains unclear. Here, the effect of FCS heat inactivation on the in vitro behavior of the clinically applied and most studied D-Lin-MC3-DMA (MC3) LNPs was investigated and compared to LNPs containing a different ionizable lipid, C12-200 (C12). Moreover, mechanisms

• equilibrium toward the β-keto enolate form, leading to the deprotonation of TC molecules and complex formation with Ca2+. Experimental results indicate that a 1:3 Ca2+/TC complex is favored at pH 6.8 (Figure 6a) [29]. The adsorption mechanism of TC onto PGC is illustrated in Figure 6b,c,d. This mechanism
