Abstract Nanotechnology-driven strategies have enabled scientists and engineers to fabricate diverse drug delivery and (bio)sensor platforms. It is now possible to develop nanoscale drug carriers for delivery of different payloads to target locations and even into cells. Furthermore, stimuli-responsive and self-propelled nanocarriers can be developed for achieving a better performance. On the other hand, biosensors are more complicated platforms, which include recognition, transduction, and signal processing elements such that they are usually fabricated through miniaturization techniques, frequent in electronic industries. Accordingly, it has been near-to-impossible to make fully functional scale biosensors so far. This chapter discusses these biosensing platforms along with wearable delivery and biosensor platforms that can be integrated into intelligent biosensing-delivery platforms.
