Upper panel: sketch of spd-SNP synthesis: dense SPs are here synthesized to prepare hollow spd-SNP via interfacial reassembly strategy promoted and guided by the competitive action of free spermidine in solution. Lower Panel: time-dependent hollow spd-SNPs formation from dense SPs: TEM images of hollow spd-SNPs after 30 min (a, e), 5 h (b, f), 15 h (c, g) and 24 h (d, h) stirring.
