Nanobiosensors for Biomedical Applications

Nanobiosensors have several advantages such as fast response, easy use, high sensitivity, specificity, real-time analysis, and portability. Over the last decade, the nanobiosensor realm has extended, and they have already showed a wide range of fields including biomedical applications, environmental analysis, food safety, and so on. A molecular imprinting method is one of the enthralling modification methods that uses molecules as templates to create cavities for recognition of targets in the polymer. It provides a large range of variability to imprint target molecules with different molecular sizes, structure, and physical and chemical properties. Owing to their unique features such as selectivity, robustness, low cost, stability, and reusability of this method, molecularly imprinted polymers have become inviting and been applied in a wide range of applications in various fields. Herein, this chapter is prepared according to the fundamentals of molecular imprinting methods, nanobiosensors, the recent applications of molecularly imprinted nanobiosensors for biomedical applications, and also conclusion and future perspectives.
