AbstractThe fabrication of polyelectrolyte multilayer capsules with controllable submicron-sized subdomains and the in situ synthesis of silver nanoparticles are reported. Because poly(acrylic acid) (PAA) is released from the shell of the capsules in the dissolution process of sacrificial cores, the remaining poly(4-vinylpyridine) (PVP) forms subdomains of spheres with controllable sizes, which can be tuned by the number of PVP/PAA bilayers. This creates capsules with special surface morphology and enables the in situ synthesis of Ag nanoparticles within the PVP subdomains on the shell of capsules. In addition, the in-situ formed Ag nanoparticles can be mostly released from PVP subdomains of capsules in pH 2.0 solution, whereas they are stable in neutral solution. These specially designed capsules containing Ag nanoparticles can be used as antimicrobial materials and potentially benefit remote drug release by laser activation.
