Stimuli-responsive clustered nanoparticles for improved tumor penetration and therapeutic efficacy. A principal goal of cancer nanomedicine is to deliver therapeutics effectively to cancer cells within solid tumors. However, there are a series of biological barriers that impede nanomedicine from reaching target cells.

Stimuli responsive nanoparticles

These stimuli-responsive nanoparticles have demonstrated, though to varying degrees, improved in vitro and/or in vivo drug release profiles. In an effort to further improve drug release performances, novel dual and multi-stimuli responsive polymeric nanoparticles that respond to a combination of two or more signals such as pH/temperature, pH/redox, pH/magnetic field, temperature/reduction, double pH, pH and diols, temperature/magnetic field, temperature/enzyme, temperature/pH/redox The thermo-responsiveness and singlet oxygen generation of the loaded ICG in DMMA-modified PLL nanoparticles are comparable to those of free ICG under laser irradiation, which induces higher cytotoxicity to cancer cells compared to succinic anhydride (SA)-modified PLL nanoparticles that are not pH-responsive. Tumor Microenvironment-Stimuli Responsive Nanoparticles for Anticancer Therapy Introduction. Cancer is a common cause of death in humans. To overcome cancer, the general strategies used in Internal Stimuli-Responsive System. 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.

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. 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 to the tumor microenvironment for programmed DOX delivery. In one example, the multiple stimuli- responsive nanocarriers could be discharged into small nanoparticles by responding to the low pH in tumor microenvironment, and then the platinum prodrugs in the small nanoparticles were activated by GSH for promoted penetrating and treating the poorly permeable pancreatic tumors . Polypeptide nanoparticles composed of thiol-modified polylysine (PLL) are cross-linked with disulfide bonds and modified with poly (ethylene glycol) (PEG) and pH-sheddable dimethylmaleic anhydride (DMMA), which exhibit reduction- and pH-responsiveness. 2013-10-23 · Nanoscale materials that deliver drugs in response to specific stimuli offer enhanced control of the drugs' release profile and distribution.
