Explore the fundamental principles governing electronic nanobiosensors through this comprehensive course covering the physics, design, and applications of nanoscale biological sensing devices. Begin with an introduction to nanobiosensors, biomolecules, and sensor geometries before diving deep into settling time analysis, including classical sensors, complex geometries, and methods to overcome diffusion limits through barcode sensors and droplet evaporation techniques. Master sensitivity concepts across different sensor types including potentiometric sensors with charge screening effects, cylindrical configurations, and ISFET pH meters, while learning about charge screening in biomolecules and strategies to enhance sensitivity. Study amperometric sensors through glucose sensor examples and techniques for beating diffusion limitations, plus cantilever-based sensors covering basic operation, static response, and nonlinear sensing mechanisms. Understand selectivity principles including molecular recognition, sequential adsorption physics, tagging and filtering methods, and noise transduction effects. Apply integrated knowledge through detailed analysis of genome sequencer systems, examining their design principles and operational mechanisms. Reinforce learning through homework solutions covering settling time calculations, sensitivity analysis for potentiometric and amperometric sensors, selectivity problems, and integrated sensor system design challenges.
