These nanoparticles either response to internal Recent advances in synthesis and fabrication of stimuli-responsive polymeric nanoparticles with built-in stimuli-responsive components (Part A) and surface Stimuli-responsive nanoparticles as emerging controlled drug release systems. The stimuli are applied as following: application of an external stimulus such as Jun 4, 2020 The rapid development of nanotechnology results in the emergence of nanomedicines, but the effective delivery of drugs to tumor sites remains Dr. Makhlouf is the editor of 13 books, 20 book chapters and over 180 articles. He is Senior Editor of Insciences Journal, Nanotechnology Section.

Although grafting‐to and grafting‐from dominate these synthetic efforts, there are opportunities for developing novel synthetic approaches facilitating controllable recognition, signaling, or sequential responses. However, it is still a great challenge to fabricate nanoparticles with spatiotemporally controllable delivery of anticancer drugs to tumors and with high therapeutic efficacy. This thesis mainly focuses on the development of stimuli responsive nanoparticles for cancer targeted therapy. These nanoparticles either response to internal stimuli such as Stimuli‐responsive upconversion nanoparticles also utilize the excessive presence of adenosine triphosphate (ATP), riboflavin, and Zn 2+ in tumors. An overview of the design of stimulus‐responsive upconversion nanoparticles that precisely target and respond to tumors via targeting the tumor microenvironment and intracellular signals is provided.

Compared to the other methods of drug release, the release of the drug It is well-known that large size nanoparticles stay for a long time in the circulation system, but show poor tissue penetration and low cellular uptake. In order to reconcile the conflicting needs for extended circulation time, extensive tumor tissue penetration, and enhanced cellular uptake for nanodrug delivery systems, we designed DOX-containing hypersensitive nanoparticles that responded This thesis mainly focuses on the development of stimuli responsive nanoparticles for cancer targeted therapy.
