The nanocarriers could accumulate and penetrate tumors, and target cancer cells for achieving different applications and functions by responding to the external and internal stimuli. (Click on the image to enlarge.) Stimuli-responsive liposomes for drug delivery The ultimate goal of drug delivery is to increase the bioavailability and reduce the toxic side effects of the active pharmaceutical ingredient (API) by releasing them at a specific site of action.

KEYWORDS diabetes, drug delivery, insulin, stimuli-responsive 1 | INTRODUCTION MSN Nanocarriers for Stimuli-Responsive Drug Delivery One of the most heavily investigated inorganic nanocarriers are those based on porous silica materials. The advent of porous silica has marked a thriving advance-ment of drug delivery for cancer treatment since their ﬁrst debut in 1952; however, International Journal of Molecular Sciences Review Stimuli-Responsive Materials for Tissue Engineering and Drug Delivery Soﬁa Municoy 1, María I. Álvarez Echazú 1, Pablo E. Antezana 1, Juan M stimuli responsive polymer integrated targeted nanomedicine is designed for combined cancer-targeted therapy and multimodal imaging using a facile preparation method. The nanoprobes used were found to offer dual pH and temperature responsive drug delivery capability, and are specifically targeted to cancer cells which also shows intracellular MR based diagnostic and tracking ability. 2021-04-07 STIMULI-RESPONSIVE DRUG DELIVERY SYSTEMS BASED ON MESOPOROUS SILICA NANOPARTICLES WONG MUN FEI EDDY School of Physical and Mathematical Sciences A thesis submitted to the Nanyang Technological University in partial fulfilment of the requirement for the degree of Master of Science The increased understanding of molecular aspects associated with chronic diseases, such as cancer and the role of tumor microenvironment, has led to the identification of endogenous and exogenous stimuli that can be exploited to devise “stimuli-responsive” materials for site-specific drug delivery applications.

Stimuli-Responsive Drug Delivery Systems Stimuli-based drug delivery systems have constituted a new platform in the under-standing of diseases at the molecular level. For this purpose, nanotechnology-based drug delivery systems offer tremendous and promising advantages in the prevention, diagnosis 2019-06-14 c) Thermoresponsive drug delivery system: The use of temperature as a signal has been justified by the fact that the body temperature often deviates from the physiological temperature (37°C) in the presence of pathogens or pyrogens. This deviation is a useful stimulus that activates the release of therapeutic agents from various temperature-responsive drug delivery systems for diseases delivery systems activated by external remote triggers are also discussed.

Thermoresponsive and other stimuli-responsive polymers employed in drug delivery systems can be activated via ultrasound stimulation. Polyethylene oxide/polypropylene oxide co-block or triblock polymers and polymethacrylates are thermal- and pH-responsive polymer groups, resp. but both have proven to have successful activity and contribution in
