Multiphoton Plasmonics: Regioselective Localization and Tracking of Biomolecules on Single Gold Nanoparticles (Adv. Sci. 11/2015)

چکیده
In article number 1500232, Y. B. Zheng and co-workers extend the scope of multi-photon plasmonic lithography to immobilize biomolecules. Protein hydrogels are precisely immobilized at the tips of a single gold nanotriangle. This process is tracked on single nanoparticles using dark-field scattering spectroscopy. These protein nano-anchors can serve as frameworks to study plasmon–molecule interactions and to assemble functional materials with hierarchical structures.

Regioselective Localization and Tracking of Biomolecules on Single Gold Nanoparticles
Selective localization of biomolecules at the hot spots of a plasmonic nanoparticle is an attractive strategy to exploit the light-matter interaction due to the high field concentration. Current approaches for hot spot targeting are time-consuming and involve prior knowledge of the hot spots. Multiphoton plasmonic lithography is employed to rapidly immobilize bovine serum albumin (BSA) hydrogel...

متن کاملSynthesis and Functionalization of Gold Nanoparticles by Using of Poly Functional Amino Acids
Synthesis and characterization of two functionalized gold nanoparticles by using of two poly functional amino acids (L-Arginine and L-Aspartic acid) are reported. The gold nanoparticles were reduced by sodium citrate and functionalized with L-Arginine at the pH of 7 and 11 and L-Aspartic acid at the pH of 7. Transmission electron microscopy, UV-Vis spectroscopy, dynamic light scattering, zeta p...
متن کاملTunable Plasmonic Nanoparticles Based on Prolate Spheroids
Metallic nanoparticles can exhibit very large optical extinction in the visible spectrum due to localized surface plasmon resonance. Spherical plasmonic nanoparticles have been the subject of numerous studies in recent years due to the fact that the scattering response of spheres can be analytically evaluated using Mie theory. However a major disadvantage of metallic spherical nanoparticles is ...
