"Préparation, caractérisation et réactivité de catalyseurs xerogels et aerogels à base de zirconium, d’aluminium et de porosité contrôlée pour les réactions d’estérification et d’hydrogénation".

Zirconium and aluminum oxides are materials of great thermal stability under different conditions and have a surface with modulable acid-base sites. The modification of these oxides by an oxo-anion, by an acid and / or metallic function gives them more stability, inhibits sintering and develops the acidity of their surface and consequently they can be used in several catalytic reactions as active phase or support.The work of this thesis focuses on the synthesis, characterization and upgrading of two types of xerogels and aerogels catalysts based on zirconium and aluminum oxides. Telluric acid was chosen as a modulator of the acidity of supports based on zirconia and alumina. Nickel was combined with telluric acid to make nickel tellurium phases on these supports, allowing the isomerization reaction.In a first part, xerogels and aerogels catalysts based on zirconia and alumina doped with telluric acid were synthesized by the “sol-gel” route then characterized and tested in the esterification reaction of acetic acid by benzyl alcohol as a model reaction for the synthesis of biodiesel. A kinetic and mechanistic study as well as the determination of the thermodynamic quantities for the esterification reaction were carried out in the presence of the catalyst having the best catalytic performance.The second part of this thesis focuses on the synthesis of zirconia and alumina-based xerogels and aerogels catalysts doped with telluric acid and nickel nitrates in one-pot, always synthesized by the "sol-gel" route. These catalysts were characterized and then tested in the isomerization hydrogenation reaction of 1-hexene as a model reaction for gasoline reformulation. We will show that the presence of nickel in the preparation prevents the formation of a Zr-Te phase, characterized on the support alone modified by telluric acid

Prostate cancer, commonly referred to as adenocarcinoma of the prostate, is the leading cause of cancer death in men in 46 countries, and it was estimated that by the end of 2018 there would approximately be 1.3 million new cases of prostate cancer worldwide. Currently, the Food and Drug Administration (FDA) approved biomarker for prostate cancer disease diagnostics Prostate Specific Antigen (PSA) is not specific to the disease itself but extends to other cases such as Benign Prostate Hyperplasia (BPH) a condition in which the prostate grows uncontrollably. This biomarker is then detected in blood samples via conventional methods which require a qualified individual to operate and are often time consuming. Examples of these methods are spectrophotometry and High Performance Liquid Chromatography (HPLC). Hence, a more efficient biomarker and method of detection is needed for prostate cancer disease diagnostics, as early detection of the disease means early treatment, which could ultimately save lives. Currently, an emerging biomarker for prostate cancer known as Alpha-Methyl CoA Racemase (AMACR) has shown to be more specific to the disease with advantages such as being a non-invasive biomarker. AMACR has been reported to be present in urine, and thus may be detected via a non-invasive method. This study proposed an economical, non-invasive electrochemical biosensor for the rapid detection of AMACR based on mercaptosuccinic acid capped tungsten telluride (MSA-WTe3) quantum dots (QDs). Nanomaterial has shown promise in terms of increasing the sensitivity and specificity of sensors. MSA-WTe3 QDs was successfully synthesized using easy, inexpensive method and was studied by various techniques such as High Resolution Transmission Electron Microscopy (HR-TEM) where the size was confirmed to be within the nanometer scale and was reported to be 2.65 nm with a good crystallinity. X-ray diffraction (XRD) confirmed the structural properties and chemical composition of the QDs and it is reported that the QDs are rich in both tellurium and tungsten and comprise of a hexagonal structure. Scanning Electron Microscopy (SEM) confirmed the successful immobilization of aptamer sequence specific to AMACR onto the electrode surface by showing a distinct conformational change when aptamers were introduced to the QDs under study. This study reports the successful detection of AMACR using an MSA-WTe3 QDs based aptasensor immobilized onto a screen printed glassy carbon electrode, with a detection limit of 0.35651 ng/mL and a limit of quantification calculated to be 1.08033 ng/mL.

Cancer, the second most common cause of death after heart disease, is a complex and multifactorial disease that up to date is still under extensive research. To achieve early detection of cancer disease the discovery of specific, sensitive and reliable biomarkers is required. Telomerase is a ribonucleo-protein complex that has been identified as an important target for cancer diagnostics and cancer therapy, because 85% of more than 950 primary tumours express telomerase activity. The standard method for the detection and quantification of telomerase activity is the polymerase chain reaction (PCR)-based assay known as the telomeric repeat amplification protocol (TRAP) assay. TRAP and other methods developed for telomerase detection have limitations for example its time consuming, requires complicated machinery, expensive equipment and reagents thus there is a need for a more sensitive, reliable and high-throughput method. Electrochemical biosensors are quickly emerging as an alternative for early detection of cancer because they can be designed to detect developing cancer biomarkers and to allow improved monitoring of cancer growth and patient therapy. This research study reported for the first time the successful fabrication and implementation of highly sensitive 3-mercaptopropionic acid indium telluride quantum dots (3MPA-In2Te3 QDs) based genosensor for detection of telomerase biomarker. The colloidal poly-dispersed 3MPA-In2Te3 QDs introduced into the genosensor system were successfully synthesized by a simple, inexpensive and reproducible aqueous method. The as prepared 3MPA-In2Te3 QDs was characterized by Ultraviolet Visible (UV-VIS) spectroscopy, Fluorescence (FL) spectroscopy, X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy and High Resolution Transmission/Scanning Electron Microscopy (HR TEM/SEM). Electro-analysis of 3MPA-In2Te3 QDs was done by Cyclic Voltammetry (CV) and Electrochemical Impedance Spectroscopy (EIS). HR-TEM studies revealed formation of small sized QDs about 6 nm in diameter while UV-VIS studies showed presence of iv absorption peaks in the ultraviolet region (100-400 nm) which confirmed the formation of these small sized QDs. The good electrochemical, optical, physical and chemical properties of the 3MPA-In2Te3 QDs allowed them to be used as a mediating platform between deoxyribonucleic acid (DNA) and gold electrode (AuE). The successful detection of telomerase was achieved by hybridization process between the probe single stranded deoxyribonucleic acid (ssDNA) drop coated on the 3MPA-In2Te3 QDs/AuE surface and its complementary ssDNA in biological buffer solution (0.10 M tris-ethylenediamine tetraacetic acid (TE) buffer solution, pH 8.00). The response of the 3MPA-In2Te3 QDs based genosensor towards different concentration of complementary ssDNA was studied by CV, square wave voltammetry (SWV) and EIS. It was observed that all three analytical techniques exhibited good linearity since their linear correlation coefficients (R2) corresponded to 0.99. However, it was observed that EIS was the best technique for the detection of telomerase compared to both CV and SWV since it showed a higher sensitivity (2.44 Ω/nM) towards detecting telomerase with a detection limit as low as 0.00014 ng/mL. Control experiments were also carried out by monitoring the hybridization process in the presence and absence of complementary ssDNA and it was determined that the QDs based genosensor was highly selective towards complementary ssDNA. In view of the attractive analytical characteristics and advantages, the ultimate goal of the developed QDs based genosensor is to apply it in real clinical samples of cancer cells or bodily fluids of cancer patients for the detection of telomerase cancer biomarker.
