Aim
The NanoBioTech Program is designed to show how nanotechnology can supercharge biosensors for faster, more sensitive, and more reliable diagnostics. You’ll learn how nanoparticles, nanostructured surfaces, and nano-enabled signal amplification improve detection of biomarkers—whether for infectious disease, cancer screening, environmental monitoring, or point-of-care testing. This course is explained in a practical, human-friendly way, so you can understand the “why” and “how” behind sensor design, validation, and real-world deployment.
