Dual temperature- and pH-responsive polymeric micelle for selective and efficient two-step doxorubicin delivery
We report a polymeric micelle drug delivery system, which enables selective intracellular uptake with external thermal stimulation, and effective release of a drug at internal acidic endosomal pH. We developed a dual temperatureand pH-responsive polymeric micelle composed of a temperatureresponsive corona segment with poly(N-isopropylacrylamide-co-dimethylacrylamide) [P(NIPAAm-coDMAAm)] and a p...
متن کاملMMP-Responsive, Proximity-activated Targeting Polymeric Nanoparticles for siRNA Delivery
SUMMARY A smart polymeric nanoparticle (SPN) with matrix metalloproteinase-7 (MMP-7) dependent proximityactivated targeting (PAT) has been designed and tested for targeted intracellular siRNA delivery to MMP-7 overexpressing tissues (i.e., tumor metastases). With this novel PAT-SPN design, a removable PEG corona mitigates cytotoxicity and nonspecific uptake in normal tissues. Exposure to MMP (i...
متن کاملPolymeric composite membranes for temperature and pH-responsive delivery of doxorubicin hydrochloride
Objective(s): Nowadays hydrogels are one of the upcoming classes of polymer-based controlled-release drug delivery systems. Temperature and pH-responsive delivery systems have drawn much attention because some diseases reveal themselves by a change in temperature and/or pH. The objective of this work is to prepare and characterize composite membrane using responsive nanoparticles into a polymer...
متن کاملpH-responsive polymeric micelles with core–shell–corona architectures as intracellular anti-cancer drug carriers
Polymeric micelles with core-shell-corona nanoarchitecture were designed for intracellular therapeutic anti-cancer drug carriers. Poly(styrene-b-acrylic acid-b-ethylene glycol) (PS-b-PAA-b-PEG) asymmetric triblock copolymer underwent self-assembly in aqueous solution to form spherical micelles with hydrophobic PS core, anionic PAA shell and hydrophilic PEG corona. The anti-cancer drug (doxorubi...
متن کاملUltra-small mesoporous silica nanoparticles as efficient carriers for pH responsive releases of anti-cancer drugs.
Mesoporous silica has emerged as one of the most promising carriers for drug delivery systems. However, the synthesis of ultra-small mesoporous silica nanoparticles (UMSNs) and their application in drug delivery remains a significant challenge. Here, spherical UMSNs (∼25 nm) have been synthesized and tested as drug carriers. Anti-cancer drugs mitoxantrone (MX), doxorubicin (DOX) and methotrexat...
