“…vitamin C) [33] to large protein/enzyme molecules. [34][35][36][37] In the case of NPs that are stabilized by anionic ligands such as carboxylic acid derivatives (citrate, tartrate, lipoic acid), the adsorption of positively charged proteins originates from electrostatic interactions (Figure 2 A). [38][39][40][41][42][43] Gold and silver NPs produced by citrate reduction were functionalized with immunoglobulin G (IgG) molecules at pH values that lie slightly above the isoelectric point of the citrate ligand.…”

Integrated Nanoparticle–Biomolecule Hybrid Systems: Synthesis, Properties, and Applications

Nanomaterials, such as metal or semiconductor nanoparticles and nanorods, exhibit similar dimensions to those of biomolecules, such as proteins (enzymes, antigens, antibodies) or DNA. The integration of nanoparticles, which exhibit unique electronic, photonic, and catalytic properties, with biomaterials, which display unique recognition, catalytic, and inhibition properties, yields novel hybrid nanobiomaterials of synergetic properties and functions. This review describes recent advances in the synthesis of biomolecule-nanoparticle/nanorod hybrid systems and the application of such assemblies in the generation of 2D and 3D ordered structures in solutions and on surfaces. Particular emphasis is directed to the use of biomolecule-nanoparticle (metallic or semiconductive) assemblies for bioanalytical applications and for the fabrication of bioelectronic devices.

“…Other than dielectric constant which affects scattering cross-section parameters, the scattering intensity also increased with particle size [22]. When the complex was in a concentration range where enhanced scattering was observed, the complex might aggregated with gold nanoparticles to form a bigger particle clusters in a loose binding manner [23], which then increased the scattering intensity. [21].…”

In the medium of H 2 SO 4 and in the presence of TiO 2+ , gold nanoparticles in size of 10 nm exhibited a weak surface plasmon resonance scattering (SPRS) peak at 775 nm. Upon addition of trace H 2 O 2 , the yellow complex [TiO(H 2 O 2 )] 2+ formed that cause the gold nanoparticles aggregations to form bigger gold nanoparticle clusters in size of about 900 nm, and the SPRS intensity at 775 nm (I) enhanced greatly. The enhanced intensity ΔI was linear to the H 2 O 2 concentration in the range of 0.025-48.7 μg/mL, with a detection limit of 0.014 μg/mL H 2 O 2 . This SPRS method was applied to determining H 2 O 2 in water samples with satisfactory results.

“…Nowadays nanodimensional structures, for example, superthin films consisting of dimmers of various metals [1, 2], clusters [3,4], DNA-bounded nanoparticles [5][6][7], and others attract considerable attention. Of special interest are the optical properties of these systems; exactly they are studied in the present work.…”

A. S. ShalinUDC 537.876The optical properties of a colloid consisting of nanoparticles are investigated on the example of interaction of three dielectric particles consisting of nonresonant atoms (whose natural transition frequencies are far from the radiation frequency) with interstitial barium atoms in the field of external optical radiation. On the basis of integrodifferential equations, expressions for the electric and magnetic fields in the wave zone are derived. The influence of distant neighbors in the ensemble on the light-scattering properties of a nanoparticle is considered, and the condition of applicability of the frequently used two-particle approximation is obtained. The spectrum of the system is investigated, and an additional resonant peak at the natural frequency of the isolated particle caused by the distant neighbor is established. Under some specific conditions, the additional peak intensity may exceed the main peak intensity of the optical near-field resonance in the two-particle system.
