Organized arrays of anisotropic nanoparticles show electronic and optical properties that originate from the coupling of shape-dependent properties of the individual nanorods. The organization of nanorods in a controllable and predictable way provides a route to the fabrication of new materials and functional devices. So far, significant progress has been… (More)
We report a predefined self-organization of gold nanorods (NRs) end-terminated with multiple polymer arms ("pom-poms") in higher-order structures. The assembly of polymer-tethered NRs was controlled by changing the structure of the polymer pom-poms. We show that the variation in the molecular weight of the polymer molecules and their relative location with… (More)
Photothermally driven volume transitions in polymer microgels have promising applications for site-specific drug delivery and photodynamic therapy. We studied the temperature-induced volume phase transitions for a series of thermoresponsive microgels of various compositions to find a system with a sharp transition in the physiologically relevant range… (More)
For various types of ensembles of metal nanorods, the frequencies of longitudinal and transverse plasmons were calculated and correlations between the plasmon frequency shifts and the topology of nanorod arrays were found. The theoretical predictions were compared with the experimentally determined optical absorption in arrays of polymer-terminated Au… (More)
Herein we demonstrate the photothermally-triggered self-assembly of poly(N-isopropylacrylamide)-functionalized gold nanorods in one-dimensional structures.
