In this paper we report on numerical study of plasmonic nanoparticle chains with long-range dipole-dipole interaction. We have shown that introduction of positional disorder gives a peak in the density of resonant states (DOS) at the frequency of individual nanoparticle resonance. This peak is referred to Dyson singularity in one-dimensional disordered structures [Dyson F., 1953] and, according to our calculations, governs the spectral properties of local DOS. This provides disorder-induced Purcell enhancement that can found its applications in random lasers and for SERS spectroscopy. We stress that this effect relates not only to plasmonic nanoparticles but to an arbitrary chain of nanoparticles or atoms with resonant polarizabilities.Comment: 9 pages, 9 figures, 41 references, regular pape

“…Such assemblies have been induced by small organic molecules, for example, mercaptoethanol 16 and destabilizing agents as salt 17 or ethanol 18 . Recently, bioinspired approaches utilizing the advantages of biological constituents for template-based assembly of nanoarchitectures have gained considerable attention 19,20 . In this context, a template can be defined as a geometrical object significantly larger than the NP to be deposited.…”

Molecular protein adaptor with genetically encoded interaction sites guiding the hierarchical assembly of plasmonically active nanoparticle architectures

The control over the defined assembly of nano-objects with nm-precision is important to create systems and materials with enhanced properties, for example, metamaterials. In nature, the precise assembly of inorganic nano-objects with unique features, for example, magnetosomes, is accomplished by efficient and reliable recognition schemes involving protein effectors. Here we present a molecular approach using protein-based 'adaptors/ connectors' with genetically encoded interaction sites to guide the assembly and functionality of different plasmonically active gold nanoparticle architectures (AuNP). The interaction of the defined geometricaly shaped protein adaptors with the AuNP induces the self-assembly of nanoarchitectures ranging from AuNP encapsulation to one-dimensional chain-like structures, complex networks and stars. Synthetic biology and bionanotechnology are applied to co-translationally encode unnatural amino acids as additional site-specific modification sites to generate functionalized biohybrid nanoarchitectures. This protein adaptor-based nanoobject assembly approach might be expanded to other inorganic nano-objects creating biohybrid materials with unique electronic, photonic, plasmonic and magnetic properties.

“…Therefore, the energetic drawbacks of 1D structures limit the accessibility of 1D nanomaterials. [8,9] In the latter example, the particles usually have a defined and inhomogeneous surface structuring, as is the case for asymmetric nanorods with different ligation at the edges [10] or Janus particles. [5] However, for soft (polymer-based) materials, a 1D shape is not easily accessible.…”

The preparation and applications of nanoparticles and nanofibers are widely described in the literature. Both types of materials have specific advantages but also drawbacks. We discuss here the methods to fabricate nanofibers from nanoparticles and vice versa by template-free methods and colloid-electrospinning. Nanoparticles and nanofibers can be also synergistically combined to yield nanostructured constructs that display highly advantageous properties such as good mechanical integrity, double protection of encapsulated substances, or the possibility to co-encapsulate payloads with different polarities.
