4. Gases. As we have seen so far, reversible, stimuli-responsive self-assembly. of nanoparticles typically relies on the formation of noncovalent. Stimuli responsive nanoparticles systems are divided into 2 classes: internal (pH, enzyme, ROS, hypoxia, redox) and external (radiation, electromagnetic, thermal) stimuli depending upon the method of inducing the delivery of the drug (Figure 1) (Taghizadeh et al., 2015; Yao et al., 2016).

2021-03-26 We developed a stimuli-responsive clustered nanoparticle (iCluster) and justified that its adaptive alterations of physico- chemical properties (e.g. size, zeta potential, and drug release rate) in accordance with the endogenous stimuli of the tumor microenvironment made possible the ultimate overcoming of these barriers, especially the bottleneck of tumor penetration.

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. This Review provides a comprehensive discussion of Stimuli-responsive nanoparticles have been designed and studied, exploring their potentiality as self-assembled materials as building blocks for the development of "smart" materials for bio-applications.

This class of stimuli-responsive nanoparticles is inactive during blood circulation and under normal physiological conditions, but is activated by acidic pH, enzymatic up-regulation, or hypoxia once they extravasate into the tumor microenvironment. 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. In this review we provide an analysis of recent literature reports on the synthesis and applications of stimuli-responsive polymeric and hybrid nanostructured particles in a range of sizes from nanometers to a few micrometers: nano- and microgels, core–shell structures, polymerosomes, block-copolymer micelles, and more complex architectures. There is increasing evidence that stimuli‐responsive nanomaterials have become significantly critical components of modern materials design and technological developments. Recent advances in synthesis and fabrication of stimuli‐responsive polymeric nanoparticles with built‐in stimuli‐responsive components (Part A) and surface modifications of functional nanoparticles that facilitate responsiveness (Part B) are outlined here. These stimuli-responsive nanoparticles have demonstrated, though to varying degrees, improved in vitro and/or in vivo drug release profiles.

ABSTRACT Nanotechnology has become an outgrowing field in novel drug delivery system. It confers several merits over conventional formulations like increased solubility and bioavailability, targeted drug delivery and a decreased dose of the Stimuli-responsive materials, which exhibit changes in one or more properties in response to an external trigger, have gained interest due to their tunability and versatility.

Stimuli-responsive nanoparticles have been designed and studied, exploring their potentiality as self-assembled materials as building blocks for the development of "smart" materials for bio-applications. Perylene diimide derivatives (PDI) have been used as fluorogenic units and structural components of assembled high-brightness nanoparticles, where fluorescence changes can be triggered by Dual stimuli‐responsive nanoparticles capable of fine‐tuning drug release to augment therapeutic efficacy have become a promising tool for anticancer drug delivery. However, the rational design of these “smart” nanoparticles for a selective delivery and controlled release of multidrug combinations in cancer cells to achieve synergistic effects remain challenging. 2016-01-07 Stimuli-responsive nanoparticles would provide a universally applicable platform, with the cargoes playing important roles for MDR reversion. To address the issue of tumor heterogeneity, neoantigens of specific tumors are required for screening for personalized therapy. 2019-03-04 Stimuli responsive nanoparticles systems are divided into 2 classes: internal (pH, enzyme, ROS, hypoxia, redox) and external (radiation, electromagnetic, thermal) stimuli depending upon the method of inducing the delivery of the drug (Figure 1) (Taghizadeh et al., 2015; Yao et al., 2016).

However, there are a series of biological barriers … 2010-01-01 Taking this into account, stimuli responsive nanoparticles present the ability to enhance therapeutic efficacy and reduce side effects. 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.
