Self-assembly of nanoparticles through hydrophobic interactions

Hydrophobic interactions modulate self-assembly of nanoparticles.

Hydrophobic interactions constitute one of the most important types of nonspecific interactions in biological systems, which emerge when water molecules rearrange as two hydrophobic species come close to each other. The prediction of hydrophobic interactions at the level of nanoparticles (Brownian objects) remains challenging because of uncontrolled diffusive motion of the particles. We describ...

Trifluoromethylated Nucleic Acid Analogues Capable of Self-Assembly through Hydrophobic Interactions.

An artificial nucleic acid analogue capable of self-assembly into duplex merely through hydrophobic interactions is presented. The replacement of Watson-Crick hydrogen bonding with strictly hydrophobic interactions has the potential to confer new properties and facilitate the construction of complex DNA nanodevices. To study how the hydrophobic effect works during the self-assembly of nucleic a...

Reversible self-assembly of gels through metal-ligand interactions

Metal-ligand interactions with various proteins form in vivo metal assemblies. In recent years, metallosupramolecular approaches have been utilized to forge an assortment of fascinating twoand three-dimensional nano-architectures, and macroscopic materials, such as metal-ligand coordination polymeric materials, have promise in artificial systems. However to the best of our knowledge, the self-a...

Self-Assembly of Microscale Parts through Magnetic and Capillary Interactions

Self-assembly is a promising technique to overcome fundamental limitations with integrating, packaging, and general handling of individual electronic-related components with characteristic lengths significantly smaller than 1 mm. Here we describe the use of magnetic and capillary forces to self-assemble 280 μm sized silicon building blocks into interconnected structures which approach a three-d...
