Unfolding and refolding of sol-gel encapsulated carbonmonoxymyoglobin: an orchestrated spectroscopic study of intermediates and kinetics

Article Abstract:

The pH-induced unfolding and refolding of the carbon monoxide-bound derivative of horse skeletal myoglobin encapsulated in porous sol-gels is probed using several optical techniques in conjunction with different unfolding/refolding protocols. UV resonance Raman spectroscopy and fluorescence are used to monitor the unfolding of the globin and exposure of the A helix to solvent.

Direct Synthesis of metal-chelating mesoporous silica: effects of added organosilanes on silicate formation and adsorption properties

Article Abstract:

The plain mesoporous SBA silicates and mesoporous SBA silicates with surface ethyl, carboxylate, and ethylenediaminetriacetic acid groups are prepared by direct synthesis. The surface area and structural order were dependent upon the amount of added functionalized silane used during synthesis.

Structure of sickle cell hemoglobin fibers probed with UV resonance Raman spectroscopy

Article Abstract:

The structure of sickle cell hemoglobin (Hb S) fibers was probed using UV resonance Raman spectroscopy. For these studies a functional analogue of Hb S, was used to study structural changes that accompany fiber formation.
