Scientists invest a lot of time and effort in coming up with cures or vaccines for new diseases. Lots of experiments, trials and tests are carried out in this regard. At the core of the entire research process is the little-known discipline, Biointerface Engineering. In this free online course, you will learn about Biointerface Engineering and its role in improving human lives. Firstly, you will study the fundamentals of intermolecular forces, the four forces of nature and the classification of these energies and pair potentials. After that, you will study the basics of thermodynamics, the strength of interactions and the hydrophobic effect. Although these might seem like complicated concepts, they form a solid foundation for the subsequent lessons, and they influence the natural environment. Have you ever wondered how spiders and other organisms could walk on water? You will get to understand how that happens as you learn about surface energy, surface tension, and surfaces’ wettability characteristic. These are closely related to adhesion, cohesion, and interfacial energy thermodynamics, which will be explained in detail.
Next, you will discover the various ways of measuring surface tension in liquids and solids. Then, you will study the solid-liquid interface and the techniques used to measure the contact angles formed when a drop of a liquid comes into contact with a solid surface. In addition, you will find out how to determine the contact angle of a finely divided powder and then learn about the two types of contact angles. This will adequately prepare you for the next topic about protein-surface interactions. Proteins are commonly known as the building blocks of life, and this topic will take you through the components of proteins and their role in the human body. Then, the factors that affect protein stability will be elaborated, followed by the methods used to measure adsorbed proteins and their advantages and disadvantages. Lastly, you will be taken through the kinetics of protein adsorption, under which you will study the step-by-step procedure of the protein adsorption process. The phenomenon of intramolecular rearrangements will be presented before the final aspect of competitive adsorption, and the Vroman effect is unveiled.
Knowledge in Biointerface Engineering plays a pivotal role in medical research, diagnostics and development of new medicines and vaccines. If you are a medical practitioner, biomedical researcher, or clinician, you will find this course fascinating, and you will easily relate to the concepts and ideas presented herein as you grow, enrich and refresh your knowledge. This course will also be helpful to nurses, pharmacists, medical officers, and clinical officers who would like to expand their knowledge base in medical research. If you are a medical student or are aspiring to join one of these professions in the future, this course will form a firm foundation for your career, and you will find it exciting and fulfilling. The demand for solutions to emerging public health problems is ever-growing, especially with the proliferation of new infectious illnesses putting millions of lives at risk worldwide. Therefore, taking this course is imperative to joining the medical research and pharmacological fraternity to help save humanity. So do not hesitate, start this course today!Start Course Now
