摘 要:Dented n anospheres show promisi ng potential in drug delivery,nano motors,***,it is still challe nging to prepare them by homopolymer self-assembly because of the strict structural requirements of the ***,we propose a strategy for preparing dented nano spheres from homopolymers by co-assembly with a short *** were co-assembled from poly(2-hydroxy-3-((4-(ethoxycarbonyl)phenyl)amino)propyl methacrylate)(PHBzoMA59)and(S)-2-((S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-phenylpro-panamido)-3-phenyIpropanoic acid(Fmoc-FF-OH).PHBzoMA homopolymers can only self-assemble into nanospheres without dent,and the addition of a short peptide in troduced hydroge n bondi ng and complementary π-π stacki ng interactions led to the final dented nano sphere *** weight fracti ons of the short peptide can be adjusted to regulate the final *** was con firmed that the radius of curvature of the dent on the surface was related to the organic bubble inside the protospheres prepared at critical aggregation concentration(CAC).The orga nic bubble can be adjusted by altering the kind of orga nic solve nt and solution pH,which allowed control over the dented nano sphere *** use of differe nt orga nic solve nts with various polarities allows adjustment of the interfacial tension,and hence the denting *** degree can also be controlled by manipulating the solution pH to(de)protonate the short peptide and ***,the versatility of this method was highlighted by using a differe nt homopolymer and the applicability of the resulting den ted nanospheres was demonstrated by decoration with gold ***,this study provided important insights and a new simple strategy to prepare den ted n anospheres in a con trolled fashion.
