Self-assembled nano-structured minerals as signatures of bacterial mineralization activities

Nano-structured Chitosan Self-aggregates as a Drug Delivery Carrier

Colloidal delivery systems including polymeric selfaggregates have been widely investigated to date, as these formulations may reduce unwanted side effects and may improve the therapeutic effects. Various characteristics of self-aggregates prepared from deoxycholic acid-modified chitosan were investigated by fluorescence spectroscopic and dynamic light scattering methods, and found to be contro...

Self Assembled Nano-Devices Using DNA

In situ helicity inversion of self-assembled nano-helices.

The handedness of nanometrical helices based on surfactant assemblies was inverted when these helices were in contact with an excess solution of chiral anions with opposite enantiomers. An important difference in the kinetics of chirality inversion at the molecular level and mesoscopic level was observed.

Water confined in self-assembled ionic surfactant nano-structures.

We present a coarse-grained model for ionic surfactants in explicit aqueous solutions, and study by computer simulation both the impact of water content on the morphology of the system, and the consequent effect of the formed interfaces on the structural features of the absorbed fluid. On increasing the hydration level under ambient conditions, the model exhibits a series of three distinct phas...

Self-assembled growth of multi-layer graphene on planar and nano-structured substrates and its field emission properties.

Vertical multi-layer graphenes (MLGs) have been synthesized without a catalyst on planar and nano-structured substrates by using microwave plasma enhanced chemical vapor deposition. The growth of MLGs on non-carbon substrates is quite different from that on carbon-based substrates. It starts with a pre-deposition of a carbon buffer layer to achieve a homo-epitaxial growth. The nucleation and gr...
