“…Fibre-like structures have been reported previously in AFM measurements on Langmuir-Blodgett films of QP deposited on mica [26] but the narrow field of view of AFM does not permit estimation of the extension of these fibre aggregates. In order to support our hypothesis high-resolution BAM images of QP, were obtained as shown in Fig.…”

“…5a). 14,81,82 In particular, speeddependent anisotropy has been shown for LB regular patterns demonstrating even the possibility to switch the orientation of these structures in a controllable way. Such experimental results have been interpreted by a non-equilibrium model based on the stability of surfactant concentration and film thickness coupled fluctuations near the meniscus of a surfactantcovered receding thin film.…”

This perspective aims to report on experimental preparation and investigation tools for engineering molecular thin films with a three-dimensional (3D) nanoscale control that is of relevant interest for different emerging applications as well as for the development of calibration standards. Such thin films may be obtained by man-made methods, self-assembly or spatio-temporal self-organization and/or by the combination of these last approaches with external tools. Understanding the main features and the physical-chemistry underlying the related ordering phenomena is in due course and a theoretical framework is under development. In this respect it is of fundamental importance to achieve the ability to get 3D structural images with a nanoscale detail. This issue is at the early stage and novel techniques like electron tomography and scanning transmission X-ray microscopy are very promising.

“…Patterning can also be achieved by using tailored mixes of different amphiphilic molecules, such as two different phospholipids or a polyelectrolyte and surfactant mixture. [152][153][154][155][156][157][158] When depositing nanoparticles by LB technique, a amphiphilic spacer is often used to prevent aggregration and provide more control over the interparticle spacing of the deposited monolayer. The orientation of phospholipid monolayers has been extensively studied, the results of which provide an insight into the mechanism of packing and surface coverage as a function of surface Figure 1.14).…”

The undersigned hereby recommends to the Department of Chemistry acceptance of the thesis Examining the gilded cage: synthesis, optical properties and plasmonic applications of gold nanocages Submitted by Alyssa Staff in partial fulfillment of the requirements for the degree of Abstract The methods of synthesis and characterization of the optical properties of gold nanocages produced by templated galvanic exchange of silver nanocubes is reported. The effect of surface modifications and substrate interactions were observed using ultra-violet, visible and near-infrared spectrophotometry and fluorescence spectroscopy. The refractive index sensitivity of the gold nanocage structures was altered using various combinations of conditions including size, shape, surface functionalization, substrate support, and capping with dielectric shells. Atomic force, scanning electron, and transmission electron microscopic methods were used for imaging and characterization of the gold nanocages. The potential applications of gold nanocages with various environmental and surface conditions were investigated based on the ability to tune the localized surface plasmon resonance modes to a series of desired wavelengths and bandwidths.Collaboration with the Albert group (Department of Electronics) was carried out with the successful assembly, as well as limit of detection and sensitivity improvements, of a protein biosensor supported on a titled fibre Bragg grating.Investigations into the fluorescence quenching effects of silica-capped gold nanocages was carried out using a tailored selection of fluorescent dyes to enable potential enhancement and/or quenching using the same nanostructure.The optical properties of gold nanocages allow for many potential uses of the same nanostructure in a wide variety of applications, including biomedical and biosensing applications. iv
