Foundations of Biointerface Engineering and Surface Interactions

At the intersection of biology, chemistry, and materials science lies biointerface engineering—the study of how synthetic materials interact with living systems. Understanding these microscopic boundaries is crucial for developing everything from advanced drug delivery systems to biocompatible medical implants. This text-based course guides you from foundational physical chemistry concepts to modern applications in biomaterial design. You will explore the molecular forces that dictate cell-surface interactions, learn how to modify surfaces to control biological responses, and discover how modern characterization techniques are used to analyze these interfaces. What you will learn: Understand the fundamental intermolecular and surface forces that govern biointerfaces; Analyze surface thermodynamics, wetting behavior, and self-assembly at biological boundaries; Evaluate protein adsorption and cell adhesion mechanisms on synthetic materials; Explore modern surface modification techniques, including self-assembled monolayers and polymer brushes; Examine current surface characterization methods used to assess biocompatibility; Apply biointerface design principles to real-world biomedical applications like biosensors and implants. We begin with core definitions of intermolecular forces before progressing to surface thermodynamics, protein-surface interactions, and modern engineering applications. Each module provides clear, written explanations and practical examples to build your conceptual confidence step-by-step. Designed for beginners, students, and professionals in biology, chemistry, or engineering seeking a solid foundational understanding of biointerfaces, with no prior advanced engineering experience required.
