Book excerpt: The use of tailored functional materials has grown enormously in recent years due to their wide-ranging applications in both science and engineering. This new volume explores the tailoring and characterization of modern materials with functional applications and for use in clean technologies in different sectors. The volume explains why the unique features of tailored nanomaterials make them ideal candidates for application in biosensor technology, pathogenic microbe detection, and modification of polyester-based ploymers. It summarizes polymer functionalization and their applications in medical science and engineering and provides an understading of tailored custom-designed solids along with computational chemistry, showing how the fast growth in solid materials has influenced different engineering sectors. With the inclusion of case studies in material science, the volume explains how tailored materials can be prepared and utilized as application-oriented composites.
