This book gives a comprehensive overview of ceramic surface functionalization approaches for ceramic materials including alumina, zirconia, titania and silica and their use as sensors, chemical and biological probes, chromatographic supports for (bio)molecule purification and analysis, and as adsorbents for toxic substances and pollutants. It provides a broad picture of the enormous possibilities offered by surface functionalization and, in addition, addresses the current challenges regarding surface analysis, characterization and stability.
