Synthesis of novel (bio) degradable linear azo polymers conjugated with olsalazine

Controlled and Targeted Drug Delivery Using Smart Nanovectors

The conventional drug delivery systems have several limitations, such as the high frequency of administration, several off-target effects, and the need for tissue specificity. Recently, smart drug shuttles have emerged, and the nano applications provided a new opportunity for advancing the drug delivery system to become tissue targeted and decrease the frequency of administration. The recent development of nanovectors as drug carriers has gone through several steps of evolution that ended with the development of logic-embedded nanovectors. Here, we summarize the different types of nanovectors and their applications in various clinical situations, and finally, we spot the light on the future of this area of research.
