Strain induced self-assembled Stranski-Krastanov growth of semiconductor islands on patterned substrate has shown great improvement of island size uniformity and spatial order. Here, we show self-assembled Volmer-Weber (V-W) growth of Si nanocrystals (NCs) on patterned SiO2 substrate via traditional chemical vapor deposition method under certain experimental configurations, induced by surface/i...

The matrix protein (M) of paramyxoviruses plays a key role in determining virion morphology by directing viral assembly and budding. Here, we report the crystal structure of the human metapneumovirus M at 2.8 Å resolution in its native dimeric state. The structure reveals the presence of a high-affinity Ca²⁺ binding site. Molecular dynamics simulations (MDS) predict a secondary lower-affinity s...

The morphology of TiO2 nanoparticles has great influence on their physical/chemical properties. Controlled synthesis with adjustable morphologies is utmost importance for target applications. Herein, a series continually shape, size and crystal structures were synthesized via the hydrolysis titanium isopropoxide, followed by self-assembly using P123 as structure-directing agent ethylene glycol ...

The self-assembly of non-ionic amphiphiles with a hydroxylated oxanorbornane head-group was controlled using amino acid units as spacers between hydrophilic and lipophilic domains to get spherical supramolecular aggregates. The ability of these systems to harbour therapeutic agents like ibuprofen, and their drug-release profiles were evaluated. Apart from directing the assembly, the intervening...

The SNAP protein is a widely used self-labeling tag that can be used for tracking protein localization and trafficking in living systems. A model system providing controlled alignment of SNAP-tag units can provide a new way to study clustering of fusion proteins. In this work, fluorescent SNAP-PNA conjugates were controllably assembled on DNA frameworks, forming dimers, trimers, and tetramers. ...

The folding and assembly of sequence-defined polymers into precisely ordered nanostructures promises a class of well-defined biomimetic architectures with specific function. Amphiphilic diblock copolymers are known to self-assemble in water to form a variety of nanostructured morphologies including spheres, disks, cylinders, and vesicles. In all of these cases, the predominant driving force for...

The plasmonic behavior of metals at the nanoscale is not only appealing for fundamental studies, but also very useful for the development of innovative photonic devices. The past few decades have witnessed great progress in colloidal synthesis of monodisperse metal nanoparticles with defined shapes. This has significantly fueled up the research of directing the metal nanoparticles to self-assem...

Gaining external control over self-organization is of vital importance for future smart materials. Surfactants are extremely valuable for the synthesis of diverse nanomaterials. Their self-assembly is dictated by microphase separation, the hydrophobic effect, and head-group repulsion. It is desirable to supplement surfactants with an added mode of long-range and directional interaction. Magneti...
