Novel self-assembled architectures have received a growing amount of attention and have significant potential for application in catalysis/electrocatalysis. Herein, we take advantage of the unique coordination and self-assembly properties of arginine for the preparation of dendritic PtCu bimetallic nanoassemblies with tunable chemical composition and structure. Strong interactions between the arginine molecules are key in driving the self-assembly of primary nanocrystals. In addition, the strong coordination interactions between arginine and metal ions is responsible for the formation of Pt-Cu alloys. We also investigated the electrocatalytic activity of various dendritic PtCu bimetallic nanoassemblies towards the methanol oxidation reaction. PtBCUl nanoassemblies exhibited excellent electrocatalytic activity and stability in comparison with other PtCu bimetallic nanoassemblies （PtlCu3, PtlCu~） and commercial Pt black, due to their unique dendritic structures and the synergistic effect between the Pt and Cu atoms.

Biocompatibility of biphasic particles supports their use in biomedical applications. With the added capability of selectively targeting cells with directionality and controlled orientation, the biphasic nanocolloids may serve as a flexible platform requiring complex, multifunctionality, as both compartments can be independently loaded as well as be surface-modified to control orientation relative to the cell surface. Taken together these properties of anisotropic biphasic nanocolloids may enable capabilities such as self-assembly into three-dimensional tissue constructs or mimicry of subcellular organization which may not be achievable with more conventional, isotropic nanoparticles.

CVD polymerization of functionalized [2.2]paracyclophanes provides a generalized, simple process by which multiple reactivity can be afforded on various substrates with a range of geometry or topology. In addition, this method provides controllable ratios of presented functional groups and minimizes cross-reactivity of biomolecules as immobilization can be done in sequence. Initial assessment of biocompatibility of CVD coatings underscore the importance of controlled ratio of surface-presented functional groups, as small differences in the chemical composition of co-polymers can have significant impact in cellular response.
