چکیده
Multicompartment Supraparticles In article number 2211244, J. Scott VanEpps, Nicholas A. Kotov, and co-workers report how l-cysteine-stabilized FeS2 nanoparticles self-assemble into supraparticles with multiple interconnected compartments. Their structure can be described by graph theoretical representations that show similar organization complexity to those of viruses. Similarly the latter, inorganic pack nucleic acid cargo for intracellular delivery while protecting it against environmental factors, such as temperature.

Synthesis, characterization, and manipulation of dendrimer-stabilized iron sulfide nanoparticles
FeS nanoparticles (NPs) were synthesized using ethylenediamine core poly(amidoamine) (PAMAM) dendrimers of generation 4 terminated with amino (G4·NH2), hydroxyl (G4·NGlyOH), and carboxyl (G4·SAH) groups, respectively, as stabilizers. These dendrimer-stabilized FeS NPs (FeS DSNPs) were characterized by ultraviolet–visible (UV–vis) spectrometry, zeta-potential measurements, and transmission elect...
متن کاملMetamaterials: Snapping Mechanical Metamaterials under Tension (Adv. Mater. 39/2015).
By exploiting snap-through instabilities, D. Pasini and co-workers design a damage-tolerant mechanical metamaterial that snaps sequentially under tension, thereby accommodating a very large deformation up to 150%. On page 5931, they describe how the nonlinear mechanical response of the metamaterial can be robustly programmed by tuning the architecture of its unit cell.
متن کاملSelf-assembly of self-limiting monodisperse supraparticles from polydisperse nanoparticles.
Nanoparticles are known to self-assemble into larger structures through growth processes that typically occur continuously and depend on the uniformity of the individual nanoparticles. Here, we show that inorganic nanoparticles with non-uniform size distributions can spontaneously assemble into uniformly sized supraparticles with core-shell morphologies. This self-limiting growth process is gov...
متن کاملTrapping Iron Oxide into Hollow Gold Nanoparticles
Synthesis of the core/shell-structured Fe3O4/Au nanoparticles by trapping Fe3O4 inside hollow Au nanoparticles is described. The produced composite nanoparticles are strongly magnetic with their surface plasmon resonance peaks in the near infrared region (wavelength from 700 to 800 nm), combining desirable magnetic and plasmonic properties into one nanoparticle. They are particularly suitable f...

Adv. Mater. 2009, 21, 1949–1953 2009 WILEY-VCH Verlag G IO N Janus particles are non-centrosymmetric particles with two distinct sides. The two sides may differ in surface wettability or in optical, electrical, or magnetic properties. Depending upon the anisotropic properties, these particles can be used as emulsion stabilizers, analogous to surfactant molecules, optical probes for chemical, bi...
