Research Interests

Interfacial adsorption is of critical importance in many industrial and biological processes, primarily due to the fact that system properties such as flocculation, flotation and biological recognition may be modified by interaction with an interface of miniscule amounts of surface-active species such as polyelectrolytes (proteins) and surfactants (lipids). Whilst the surface excess of the adsorbate is often of importance in inducing behavioral change, structural properties such as the polar orientation and degree of conformational order are also critical. A great deal of research has been performed on quantifying the effect of variables such as concentration of the surface-active species, electrolyte concentration, pH and temperature on surface excess. Comparatively little work however has focused on determining the effect of the same system properties on the detailed structure of the adsorbed layer. The primary reason for this paucity of data is the lack of techniques capable of providing interface specific structural information. The aim of our research is to determine detailed conformational informational of interfacial species in industrially and biologically relevant systems with the intention of gaining insight into how the surface structure affects the properties of the system. The primary technique employed is the surface specific second order non-linear optical technique of Sum Frequency vibrational Spectroscopy (SFS). This high energy laser technique involves overlapping, both spatially and temporally, a visible beam of fixed frequency and an infrared beam of tunable frequency on an interface. A third beam is emitted from the interface, the frequency of which is the sum of the two incident frequencies. Detecting this emitted light as function of the infrared wavelength produces a vibrational spectrum that is upshifted into the visible. The polar orientation of species resident at the interface is determined from the relative phase of the resonance signal, that is, whether ‘peaks’ or ‘dips’ are observed in the spectrum. Conformational information of the species is reflected by the relative strength of the resonance signals. The detailed structural information of interfacial species obtained by SFS is complemented by information obtained by a range of other surface techniques in order to provide a more complete picture of the interface. Specifically, the surface excess of the adsorbate is determined by appropriate linear transmission or reflection spectroscopies, for example UV-visible transmission and infrared attenuated total reflection. Further, extensive use of Atomic Force Microscopy is made in order to associate the surface excess and structural information with interfacial topography.

Current projects Include:

Cellulose Based Substrates for Interfacial Adsorption Studies This project is aimed at the development of cellulose based substrates which may be probed spectroscopically by both linear and non-linear optical techniques. The optimized substrates will be employed to elucidate interfacial adsorption on cellulosic surfaces in systems relevant to the pulp and paper industry. The main requirement of the substrates is one of optical flatness, an issue that will be addressed by the construction of composite substrates comprising a thin layer of cellulose supported on a suitable optical element. Determination of the surface excess of a polyelectrolyte or surfactant of interest on the cellulose layer will be achieved by selecting a supporting material that is transmitting in the spectral region required. This will allow either ex-situ transmission or in-situ Attenuated Total Reflection, ATR, measurements to be made. Conformational studies of the adsorbates will be performed by Sum Frequency vibrational Spectroscopy, SFS. Gold will be employed as the support substrate for the thin cellulose layer in the SF experiments due to the favorable non-linear optical response of this metal.

Conformational Studies of Lipid Molecules Comprising Model Membranes Biological membranes consist of a bilayer of primarily lipid molecules which contain a polar headgroup and two pendent hydrocarbon chains. The conformational structure of the alkyl chains of the lipid is known to influence membrane properties such as the rigidity, the degree of in-plane fluidity and trans membrane transport phenomena. However, detailed studies precisely characterising the structural effects of lipids on membrane properties are complicated by the difficulty of deconvoluting the complex native systems. Consequently there is a strong need for a model membrane system that accurately reproduces the characteristics of a native membrane and that may be studied by techniques that yield conformational information. This project aims to construct asymmetric membranes consisting of two different lipid molecules each in a separate layer of the bilayer. The degree of conformational order of the alkyl chains of the lipids will then be determined under a wide range of conditions by application of Sum Frequency vibrational Spectroscopy (SFS).
