    The formation of cellular adhesion complexes is important in normal and pathological cell activity, and is determined by the force imposed by the combined effect of the distribution of extracellular matrix molecules and substrate rigidity.

    A bottom-up process to achieve rapid growth of micrometre-sized three-dimensional nanocrystal superlattices during colloidal synthesis at high temperatures is revealed by in situ small-angle X-ray scattering; the process is applicable to several colloidal materials.

    The mechanism of hydrogen spillover is described using a precisely nanofabricated model system, explaining why it is slower on an aluminum oxide catalyst support than on a titanium oxide catalyst support.

    Surface patterning of nanoparticles with polymer patches is achieved in a poor solvent for the polymer by controlling the ratio between the sizes of polymer molecules and nanoparticles.

    Certain bacteria contain strings of magnetic nanoparticles and therefore align with magnetic fields. Inspired by these natural structures, researchers have now fabricated synthetic one-dimensional arrays of such particles.

  • Letter |

    Placing a light emitter in an ultra-small optical cavity results in coupling between matter and light, generating new forms of emission that can be exploited in practical or fundamental applications; here, a system is described in which strong light–matter coupling occurs at room temperature and in ambient conditions by aligning single dye molecules in the optical cavities between gold nanoparticles and surfaces.

    Hydroxycarbonate minerals such as zincian malachite and aurichalcite are well known precursors to catalysts for methanol-synthesis and low-temperature water–gas shift reactions; here, a supercritical antisolvent method is used to prepare highly stable georgeite—a hydroxycarbonate mineral that has hitherto been ignored because of its rarity, but which is found to be a superior catalyst precursor.

    The authors report a new biomimetic nanodelivery platform in which polymeric nanoparticles enclosed in the plasma membrane of human platelets are used for disease-relevant targeting, and the therapeutic potential of the concept is demonstrated in animal models of coronary restenosis and systemic bacterial infection.

    Substitutional atomic doping is a process by which atomic defects are introduced into a host material, altering its properties; substitutional doping of cadmium selenide or lead selenide nanocrystal lattices with gold nanocrystals has now been achieved, the key being to ensure that the dopant nanocrystals are similar in size to the host nanocrystals.

    Alloying steel with aluminium improves the material’s strength-to-weight ratio, but the resulting formation of brittle intermetallic compounds within the steel matrix reduces its ductility; here the morphology and distribution of the intermetallic precipitates are controlled to alleviate this problem.

    Very slow cooling, over several days, of solutions of complementary-DNA-modified nanoparticles through the melting temperature of the system produces nanoparticle assemblies with the Wulff equilibrium crystal structure, thus showing that DNA hybridization can direct nanoparticle assembly along a pathway that mimics atomic crystallization.

    Silver nanoparticles are susceptible to oxidation and have accordingly received less attention than gold nanoparticles; ultrastable silver nanoparticles are now reported, which can be produced in very large quantities as a single-sized molecular product, and the origins of their enhanced stability are elucidated using a single-crystal X-ray structure and first-principles calculations.

    An electron tomography method is demonstrated that can determine the three-dimensional structure of a gold nanoparticle at 2.4 Å resolution, including the locations of some of the individual atoms within the sample.

    The ligand-mediated binding of colloid particles to each other is more effective if the particles are flat rather than curved. This finding opens up opportunities for the design of self-assembling materials.
