Texto completoIt is well known that the optical properties of nanoparticles of noble metals, in particular gold and silver, deviate strongly from those of macroscopic metals. For sizes between ten and a few hundred nanometers, they are dominated by surface plasmons (SPs) described by purely classical models. On the other hand, clusters of a few tens of atoms behave like quantum systems inducing new optical behaviors. The structure of the nanoparticles and the dielectric environment can affect the optical properties. In this thesis I used a scanning transmission electron microscope (STEM) fitted with an electron energy loss spectrometer (EELS) to measure, in parallel, the optical and structural properties of individual nanoparticles. I present how complementary experiments (STEM-EELS and optical absorption) on sizeselected small silver nanoparticles embedded in silica yield at first inconsistent results: while optical absorption shows no size-effect in the range between only a few atoms and ~10 nm, a clear spectral shift is observed in STEM-EELS technique. Our quantitative interpretation, based on a mixed classical/quantum model which takes into account all the relevant quantum effects, resolves the apparent contradictions, not only within our experimental data, but also in the literature. Our comprehensive model describes how the local environment is the crucial parameter controlling the manifestation or absence of quantum size effects. Secondly, I was interested in the purely classical region through lithographed structures of a few hundred nanometers. Although triangular plasmonic cavities have been widely studied in the literature, a classification in terms of plasmonic modes of breathing and edge was missing. In this study, experimental STEM-EELS results, analytical models and classical simulations enabled us to describe the nature of the different modes

Texto completoLa scoperta di nuovi target anticancro è il fattore chiave per lo sviluppo di terapie sempre più efficaci. Lo studio del legame selettivo a sequenze di DNA a doppia elica nella classica forma B è stato largamente impiegato al fine di direzionare piccole molecole verso porzioni polinucleotidiche definite. Più recentemente, il riconoscimento (da parte di ligandi) di porzioni non canoniche di DNA si può tradurre in un metodo vantaggioso per indirizzare questi composti verso regioni distinte del genoma. A tale proposito, le strutture G-quadruplex rappresentano un sistema interessante poiché sono ritenute fisiologicamente significative. Queste strutture “non-canoniche” di DNA si trovano alle estremità del cromosoma (telomeri) così come in varie regioni promotrici di oncogeni in cui vi è un’abbondante presenza di residui guaninici e sembrano coinvolte nella regolazione di importanti eventi biologici. Pare infatti che l'induzione e la stabilizzazione di strutture G-quadruplex dalle parte di piccole molecole porti all'inibizione dell'attività della telomerasi interferendo con l'interazione tra l’enzima e il suo substrato a singola catena. Un simile meccanismo molecolare è probabilmente coinvolto anche nel controllo della regolazione dell'espressione genica e può portare alla soppressione della trascrizione di un oncogene. Di conseguenza, “l’approccio G-quadruplex” si rivela molto interessante per lo sviluppo di una strategia anticancro specifica caratterizzata anche da una riduzione drammatica degli effetti collaterali, tipici della chemioterapia. Lo scopo di questo lavoro è lo studio delle interazioni tra nuove famiglie di piccole molecole e diverse conformazioni di DNA G-quadruplex. Queste nuove molecole sono state opportunamente progettate apportando sostituzioni di atomi o gruppi funzionali basate sulla valutazione di composti precedentemente studiati al fine di aumentare la loro selettività per strutture G-quadruplex e di ridurre gli effetti tossici. Le proprietà biofisiche e biologiche di tutti i nuovi derivati sono state valutate al livello molecolare e cellulare. Il lavoro di tesi si divide in tre parti in base alle caratteristiche strutturali dei composti. La prima parte è dedicata alla studio di dicationi eterociclici: si è cercato correlare modifiche nella conformazione molecolare con l’affinita’ verso strutture G-quadruplex. In particolare è stato possibile razionalizzare cambiamenti della modalità di legame in base alla struttura dei composti esaminati. Tuttavia una correlazione fra i risultati biofisici (affinità G-quadruplex) e biologici (inibizione della telomerasi e citotossicità) non è risultata sempre definita. Ciò può suggerire il coinvolgimento di bersagli cellulari diversi dal telomero umano. Nel capitolo 3, sono state studiate le proprietà di legame al DNA di alcuni derivati fenantrolinici in presenza ed in assenza di Ni (II) e Cu (II). Abbiamo confermato che complessi caratterizzati da diverse geometrie che coinvolgono una, due o tre molecole per ione possono compromettere o meno il riconoscimento del DNA o determinare cambiamenti conformazionali dell'acido nucleico. Per concludere, il capitolo 4 è dedicato allo studio di derivati del transplatino. In particolare ci siamo focalizzati nel definire la capacità dei composti di formare addotti, la natura dei complessi e la cinetica di formazione del complesso non solo con DNA a doppio filamento ma utilizzando anche substrati a singola catena come il G-quadruplex. I risultati hanno dimostrato come diverse modifiche strutturali possano avere un ruolo importante nell’interazione dei composti con gli acidi nucleici. E’ risultata interessante la loro preferenzialità a reagire con porzioni di DNA a singolo filamento rispetto a sequenze a doppia elica. Ciò è probabilmente dovuto ad uno sfavorevole orientamento dei gruppi reattivi quando la molecola interagisce con il substrato di DNA. Di conseguenza, i composti sembrano formare un cross-link tra due filamenti non appaiati. A livello cellulare, questi risultati riflettono una distinta distribuzione del sito di platinazione all’interno del genoma rispetto al cisplatino e perfino rispetto al transplatino. I risultati ottenuti incrementano la conoscenza disponibile sull’interazione tra DNA e piccole molecole. In particolare è emerso che la conservazione della modalità di interazione si correla con effetti biologici definiti. Al contrario, una variazione della modalità di legame può portare a effetti citotossici differenti. Ciò può fornire una spiegazione razionale per una successiva ottimizzazione della struttura dei composti finalizzata allo sviluppo di nuovi agenti antitumorali efficaci e selettivi.

Houwaart, Torsten. "Cobalt porphyrins on coinage metal surfaces - adsorption and template properties". Thesis, Lyon, École normale supérieure, 2014. http://www.theses.fr/2014ENSL0927.
Texto completoThis thesis is a theoretical study on the cobalt porphyrin - coinage metal surface interface with the DFT code VASP. The necessary DFT framework has been introduced in chapter 1. The structure of the Java program jBardeen for STM simulation is explained in chapter 2 and the source code is attached as Appendix. A study of the adsorption of CoTPP on coinage metal surfaces has been undertaken in chapter 3. Different parameters of the calculation have been evaluated: the adsorption site and the geometry of both the molecule and surface have been investigated with respect to the xc-functional and dispersion correction used. A most stable adsorption site -bridge down- is identified. Consequently, this most stable site was investigated for its electronic structure. Calculated STM images with the jBardeen code were compared with an experiment of CoTPP on a Cu(111) surface with sub monolayer coverage. In chapter 4 an Fe adatom was introduced to the CoTPP on Ag(111) system. Three symmetrically different binding sites for the Fe atom were identified on the macrocycle, labelled the bi-, brd- and bru-positions for bisector, bridge down and bridge up respectively. A magnetic moment could be evidenced which was mainly located on the Fe atom. Possible pathways between the four symmetrically equivalent bisector sites were investigated with different methods. Single point calculations in vacuum and Nudged Elastic Band (NEB) of the whole system revealed a barrier height of slightly above 0.2 eV going from bi- to the brd-position. A vibrational analysis showed that switching of the Fe atom is likely, when perturbed out of equilibrium in the brd- and bru- positions
