ABSTRAK

Nanomaterials either of the core-shell or alloy type have attracted significant attention due to their promising use in a host of biomedical applications such as bioimaging biosensing drug delivery and cell labeling. Although nanomaterials with well-controlled surface properties and structures can be synthesized and to a certain extent also characterized understanding and validating the structureproperty relationships of these materials for biomedical applications requires rigorous characterization techniques. Due to the complexity of most biological environments the introduction of nanomaterials characterization techniques that can provide useful information on surface structure atomic distribution segregation and composition is critical in developing new systems with improved properties. During the past two decades X-ray absorption spectroscopy XAS has been actively employed in investigating the structural aspects of nanomaterials and in many instances can provide useful information over many characterization techniques. In this chapter we provide an overview of the current research and developments in applying XAS techniques to the characterization of spherical and anisotropic core-shell and alloy nanomaterials. The importance of understanding the structure and surface properties of nanomaterials and the capabilities of XAS in developing nanostructured materials are also discussed.
