Biointerface Engineering: Protein Aggregation and Biomaterials
Biointerface Engineering: Surface Modification and Characterization
Implants are required in certain medical conditions such as fractures dental injuries or hip disorders that necessitate replacement procedures. The commonly used materials for implants are metals such as titanium alloys stainless steel and alumina (aluminum oxide). These are non-biological and are foreign objects to the body and thus require particular improvements to make them compatible with the body’s systems. In this course you learn about the surface modification of materials to make them biocompatible. Firstly you are introduced to biomaterials their applications and bio-interfacial interactions. The objectives and approaches of surface modification are examined. After that study the purpose of surface modifications their physicochemical properties and the methods and challenges of modifying surfaces. You will also study calcium phosphates and their use in coating titanium alloys with a specific focus on Ti-6Al-4V an alpha-beta titanium alloy with high specific strength and excellent corrosion resistance. Then learn about cell adhesion and the relationship between surface roughness and wettability.Next study the methods used in the characterisation of surfaces. You will discover the two broad categories of surface characterisation: microscopic and spectroscopic techniques and their respective sub-categories. These processes establish the properties of the material surfaces such as roughness hydrophobicity or hydrophilicity which help design the appropriate surface modifications to suit the intended purpose. For instance for bodily implants the materials should minimise bacterial adhesion and possess antifouling properties. After that you will be introduced to self-assembled monolayers (SAMs) a method of modifying surfaces to make them biocompatible. The process of forming them and the different types of SAMs will be explained. The effect of modification on interface properties is explored. Then you are taken through the impact of SAMs on bio-interfacial interactions where you will study the surface functionalisation and modifications of titanium alloys. Finally learn about the impacts of surface energy protein adsorption and secondary structure.Knowledge of the characterisation and modification of surfaces is crucial in medicine especially where implants are involved. Implants are primarily used in orthopaedic surgery for bone strengthening joint replacement surgery vertebrae replacement and artificial tooth implants. Heart pacemakers and contraceptive implants are other examples of bodily implants that need to be assessed for biocompatibility and modified to suit the intended purpose. This course is designed for medical professionals including general practitioners orthopaedic surgeons nurses and medical officers who would like to refresh or upgrade their knowledge and skills. If you are a medical student or aspiring to join a medical practice in the future then this course is for you. You will find it very interesting and it will form an excellent foundation for your career. So why wait? Start now!
