Full textWe studied the copolymer PS-b-PAA Langmuir films and the formation of non-organic nanostructures by reduction of silver ions Ag+ in their neighborhood. On the one hand, we have precisely determined the structure of these copolymers at the air-water interface for different pH with many complementary techniques (isothermal, ?-A, neutron reflectivity, grazing-incidence x-ray scattering). This study proved that the classic interpretation of these isotherms should be reconsidered and we emphasized the major role played by the spreading solvent. This (solvent) is partially absorbed by the surface after the deposit and the mixed copolymer-solvent monolayer is created by the surface nanostructure. These nanostructures have a well-defined typical size. When the PAA chains are neutral, the pseudo-surface observed on the isotherms correspond to the reversible expulsion of the solvent to a subphase which induces a reorganization of the nanostructures. In the case of charged PPA chains, the isotherm does not show the flat surface. This is due to the electrostatic repulsion between these chains. The compression of the film induces the ?dive? of a part of the monolayer ? copolymer and solvent ? towards the volume. On the other hand, we studied the behavior of these charged copolymer films in the presence of silver ions Ag+ in the before and after reduction. We showed that the presence of ions Ag+ ions induces the collapse of the PAA chains at the interface. The ions reduction by surface x-rays radiolysis produces silver colloids following a ?bi-continuous? 2D structure with a typical length scale. However, the photo-chemical reduction does not seem to produce homogenous and dense layers of colloids

Full textDiacetylenes (DA), specially 10,12-Pentacosadyonic acid, have been extensively studied due to their interesting structural, spectral, and optoelectronic features. In particular, their unique colorimetric and fluorescent transition of PDAs in response to different external stimuli makes them a novel class of sensing materials, and numerous applications of PDAs as bio- or chemosensors, generally using vesicles, have been explored. In order to improve sensibility of these sensors, we propose a monolayer-thin sensor. For this we synthesized and studied a novel DA family, denominated by 13-nOH (n =2,3,4,6,8,9), using smaller aliphatic chains and an alcohol head. Comparatively to the very used PCDA, these molecules are less reactive, but, opposed to PCDA, they are stable as a monolayer at water interface. We thoroughly study the interfacial properties and structure of these molecules using Langmuir techniques accompanied by microscopy probing techniques, such as Brewster-angle microscopy (BAM), Atomic-force microscopy (AFM) and X-Ray techniques such as grazing-incidence X-Ray Diffraction (GIXRD) and X-Ray Reflectivity, while reactivity has been studied using UV-Visible spectroscopy. A very dissimilar behavior has been observed between these molecules, varying highly with n. Particularly, 13-4OH has shown a behavior that to our knowledge has yet to be observed in 2D monolayers, disorganizing when compressed. Adding to this study, MD simulations have been performed, replicating the Langmuir studies, in order to get a thorough look on the structure evolution. Due to the inexistence of forcefields for acetylenes and di-acetylenes, this had to be parameterized and was done using a linear model based on an extensive number of simulations in order to predict the correct parameters. Finally, the potential of nanometer thin PCDA layers as sensors was tested by characterizing the radiosensitization effect of AuNp and their potential in cancer treatment. To do this, multiple types of samples, prepared using electron-beam lithography, spincoating and Langmuir-transfer have been studied and although, we were not able to quantitively characterize the effect, an effective model of study has been engineered
