A simple N,N'-dicyclohexylurea adduct of β-alanine can self-assemble to generate nano-morphological versatility in response to different environmental conditions.

A single ω-amino acid based molecule "Boc-β-Ala-N,N'-dicyclohexylurea" can form diverse nanostructures such as nano-vesicles, nano-tubes, nano-rods and nano-fibrils by self-assembly, in response to various environmental conditions. Interestingly, the nano-vesicular structures generated from this molecule can encapsulate the highly potent anticancer drug methotrexate, which can be released by salt triggered disruption of these vesicles. This phenomenon indicates the probability of its use in targeted delivery of drugs or any bio-active molecule, utilizing this encapsulation efficiency.

Study of the nano-morphological versatility by self-assembly of a peptide mimetic molecule in response to physical and chemical stimuli.

A small peptide mimetic molecule can form diverse nanostructures such as nano-vesicles, nano-tubes and nano-ribbons/fibrils by self-assembly, in response to various physical and chemical stimulations.

Effect of surface plasmon resonance on the photocatalytic activity of Au/TiO2 under UV/visible illumination.

In this study, gold-loaded titanium dioxide was prepared by an impregnation method to investigate the effect of surface plasmon resonance (SPR) on photoactivity. The deposited gold nanoparticles (NPs) absorb visible light because of SPR. The effects of both the gold content and the TiO2 size of Au/TiO2 on SPR and the photocatalytic efficiency were investigated.
