Summary

The requirement for exact and noninvasive diagnostic devices is urgent for identifying particular and important analytes connected with disorders, of envisioning the area and dissemination of influenced cells, and of reporting the movement of a therapeutic agent. With the use of imaging techniques, delivery of drugs or other micro- or macromolecules is possible at the targeted location with the help of a smart polymeric complex. Delivery systems include three main categories, namely, low molecular weight drugs, protein and enzyme delivery, and final gene delivery. This chapter focuses on smart complex materials, which may be nano- or supramolecular built of stimuli-responsive (SR) polymers that find use in numerous applications in the biomedical field. One important feature of SR material is reversibility, that is, the ability to return to its initial state. Nanoparticles or quantum dots (QDs) linked to responsive polymer were designed or synthesized for the development of polymeric sensors.
