A scalable and reproducible approach to synthesize novel multifunctional spherical Au nanocluster assemblies is devised by T. Wang, C. Wang, and co-workers on page 3162.The assemblies are encapsulated by polyacrylic acid (PAA)/calcium phosphate (CaP) shell nanoparticles and show aggregation-enhanced fl uorescence properties.The resulting core-shell nanoparticles possess a high payload of doxorubicin for pHsensitive drug delivery for dual-modal computed tomography and in vivo fl uorescence imaging-guided liver cancer chemotherapy. NanoparticlesThe interparticle distance in gold nanoparticle trimers is modulated by T. Takarada and co-workers on page 3153.Each particle has one long DNA (green) and several short DNAs (orange).The long DNA serves to align the particles on a template DNA (purple).When the complementary DNA (blue) is hybridized to the short DNA, the interparticle distance is spontaneously decreased in the presence of salt (right front).However, no shrinkage occurs with the terminal-mismatched DNA (yellow) under the same conditions (left front). Energy StorageHeteroassembly of low-dimensional building blocks is important but challenging in various applications.On page 3135, a method using aerosol spray drying is developed by Y. Lu, F. Wei, and co-workers.Using this method, oxide nanocrystals and carbon nanotubes are assembled into three-dimensional mesoporous nanocomposites, which offer remarkable energy-storage performance.The synthesis method is facile and broadly applicable in preparing composite materi als.
