Spectroscopic Analysis of keratin endogenous signal for skin multiphoton microscopy: erratum.
Optics express, 2005Co-Authors: Ana-maria Pena, M Strupler, T Boulesteix, Gaston Godeau, M Schanne-kleinAbstract:We recorded one-photon excited fluorescence (1PEF) and two-photon excited fluorescence (2PEF) spectra of purified keratin from human epidermis, and determined the action cross section of this endogenous chromophore. We used this Spectroscopic Analysis to analyse multiphoton images of skin biopsies and assign the intrinsic fluorescence signals in the epidermis. We observed a good agreement between in situ and in vitro 2PEF spectra of keratin. This study provides a comprehensive characterization of the 2PEF signal of the keratins from the epidermis, and will be of practical interest for multiphoton imaging of the skin.

FT-Raman Spectroscopic Analysis of pigments from an Augustinian friary
Analytical and bioanalytical chemistry, 2010Co-Authors: Howell G. M. Edwards, Emma M. Newton, Sonia O'connor, D. EvansAbstract:The Raman Spectroscopic Analysis of several stone samples with applied red pigments obtained from an archaeological excavation of an Augustinian friary discovered during the construction of an extension to Hull Magistrates Court in 1994 has revealed a surprising diversity of composition. Cinnabar, red lead and haematite have all been identified alone or in admixture; the cinnabar is exceptional in that it has only been found heavily adulterated with red ochre and red lead, as the other two pigments are found alone. There are signatures of limewash putty, which has been applied to the stone substrate prior to the painting, which is characteristic of the Roman method of wall painting, and there are no traces of gypsum found in the specimens studied. This evidence indicates an early mediaeval method of stone decoration.

Raman Spectroscopic Analysis of the enigmatic Comper pigments
Analytical and Bioanalytical Chemistry, 2007Co-Authors: Howell G. M. Edwards, Rosalind Wolstenholme, David S. Wilkinson, Christopher Brooke, Michelle PepperAbstract:An early church decoration project carried out by Sir Ninian Comper in 1896–98, involving the rood screen and canopy in St. Mary’s, Egmanton, is currently undergoing restoration. Despite the rather prolific works of this famous ecclesiastical architect, there is little information available about the actual pigments that he used in his projects that gave rise to the special nomenclature “Comper green” and “Comper red”. Specimens of green, red, black, grey, white and blue paint from this work have been made available for Raman Spectroscopic Analysis, and their identification has been achieved for the first time. The characteristic red and green pigments used in Comper’s work, Comper green and Comper red, are both seen to be mixtures; in the former, Raman bands from chrome yellow (lead(II) chromate) and Prussian blue are identified, and the latter is confirmed as being a mixture of vermilion (mercury(II) sulfide) and barytes (barium sulfate). The other colours are found to represent a rich diversity of palette and include haematite, lead tin yellow (type II), lamp black, gypsum, anhydrite, hydrocerussite and calcite. The information from this first Raman Spectroscopic study of Comper’s palette will assist the conservation and restoration of an important nineteenth century church decoration.
