Mineral-Surface Chemistry of Hydroxyapatite and Urea-Rich Solutions
<p>On this planet the development of life requires six essential elements: C, H, O, N, P, and S. These elements are present in gaseous form, with the exception of phosphorus, which is primarily found in solid mineral sources. Phosphorus in biological systems is significant through its involvement …

In Situ Vibrational Spectroscopic and Electrochemical Study of Electrodeposition Additives on Copper Surfaces
… surfaces was investigated using SERS and PM-IRRAS. The results show that silicotungstate interacts with Cu surfaces. This interaction is shown to be potential-dependent; alpha-SiW12O404- associates with the Cu surface to a greater extent as the potential is stepped negatively. As the …

Synthesis and Assembly of Dihydroindolizines on Gold Surfaces for Light Induced Work Function Alterations
… infrared reflection absorption spectroscopy (PM-IRRAS) allows analysis of the characteristic dihydroindolizine C=C (1559 cm-1) and pyridinium (1643 cm-1) stretch as a function of photoexcitation. Structural assignments of this photochromophore are corroborated to density function theory …

Electrochemical and spectroscopic analysis of collagen films and lipid bilayers on biomaterial surfaces
… of proteins. This thesis aims at the development of a stable and relatively simple system to model the native protein film on a biomaterial surface under the influence of electric fields. Collagen was chosen as the adsorbing protein and gold as the substrate material. Capacitance …

Multidentate Alkanethiols with Cyclohexyl and Pyridyl Frameworks Forming Self-Assembled Monolayers on Gold
… infrared reflection absorption spectroscopy (PM-IRRAS), and X-ray photoelectron spectroscopy (XPS). CyTSH was found to generate multilayer thin films with many unbound thiol species and oxidized sulfur moieties (e.g., disulfides and sulfone). In contrast, 3C1CyTSH was found to generate …

Surface Plasmon Resonance Imaging Biosensors for Cancer Diagnosis: Detection of Circulating Tumor DNA
… infrared reflection-absorption spectroscopy (PM-IRRAS). Complementary acoustic (quartz crystal microbalance with dissipation, QCM-D) and plasmonic (surface plasmon resonance imaging, SPRI) techniques have been employed to monitor the adsorption of bovine serum albumin (BSA), used as standard …

Spectroelectrochemical investigation of passive layers formed on electrode surfaces
… infrared reflection absorption spectroscopy (PM-IRRAS), and sum frequency generation (SFG). It is a good test for the viability of shell-isolated nanoparticle enhanced Raman (SHINERS) particles in investigating surface film formation on single crystal Cu. SHINERS did not reproduce the face …

Chemically Specific Protein Immobilization Strategies on Analytical Surfaces
Chemically specific protein immobilization strategies on surfaces were explored. The goal of this work is to capture and bind proteins to the surface without losing their physiological properties. This approach permits to express functions of proteins after immobilization process. Using …
