TLDR
In this article, a review examines physico-chemical requirements necessary to achieve stimuli-responsiveness in heterogeneous polymer networks as well as discusses recent developments and future trends while individual structural components of polymeric networks are responsible for localized chainresponsiveness, desirable spatial and energetic network properties are necessary for collective and orchestrated responsiveness to external or internal stimuli.About:

Cobalt Cross-Linked Redox-Responsive PEG Hydrogels: From Viscoelastic Liquids to Elastic Solids
TL;DR: Cobalt cross-linked redox-responsive 4-arm histidine-modified PEG (4A-PEG-His) hydrogels, which can be switched from self-healing viscoelastic liquids to form stable elastic solids through a simple oxidation step from Co2+ to Co3+.
Journal ArticleDOI
Single chain structure of a poly(N-isopropylacrylamide) surfactant in water.
TL;DR: In this paper, the authors present atomistic simulations of a single PNIPAM-alkyl copolymer surfactant in aqueous solution at temperatures below and above the LCST.
Journal ArticleDOI
Redox‐ and pH‐Responsive Cysteamine‐Modified Poly(aspartic acid) Showing a Reversible Sol–Gel Transition
TL;DR: Injectable aqueous solutions of thiolated poly(aspartic acid) can be converted into mechanically stable gels by oxidation, which can be useful for drug encapsulation and targeted delivery.
Journal ArticleDOI
Biomedical applications of magneto-responsive scaffolds
TL;DR: The current fabrication methods used to synthesize magneto-responsive materials, efforts to predict and characterize magneto -responsive biomaterial behavior, and the application of magnets as controlled drug delivery systems, tissue engineering scaffolds, and artificial muscles are discussed.
Journal ArticleDOI
Biomimetic polymers responsive to a biological signaling molecule: nitric oxide triggered reversible self-assembly of single macromolecular chains into nanoparticles.
Jinming Hu,Michael R. Whittaker,Hien T. T. Duong,Yang Li,Cyrille Boyer,Thomas P. Davis,Thomas P. Davis +6 more
TL;DR: Upon exposure to NO--a ubiquitous cellular signaling molecule--the NAPMA- and APUEMA-labeled thermoresponsive copolymers exhibited substantial changes in solubility, clearly characterized by tuneable LCST behavior, thereby inducing self-assembly into nanoparticulate structures.

How useful is SBF in predicting in vivo bone bioactivity
Tadashi Kokubo,Hiroaki Takadama +1 more
TL;DR: Examination of apatite formation on a material in SBF is useful for predicting the in vivo bone bioactivity of a material, and the number of animals used in and the duration of animal experiments can be reduced remarkably by using this method.
Journal ArticleDOI
Conjugated polymer-based chemical sensors.
TL;DR: When considering new sensory technologies one should look to nature for guidance, as living organisms have developed the ultimate chemical sensors.

Investigations on the theory of the Brownian movement
TL;DR: Alfaro et al. as discussed by the authors conservado en la Biblioteca del Campus de Mostoles de la Universidad Rey Juan Carlos (sign. 530.12 EIN INV).
Journal ArticleDOI
Photomechanics: directed bending of a polymer film by light.
TL;DR: It is shown that a single film of a liquid-crystal network containing an azobenzene chromophore can be repeatedly and precisely bent along any chosen direction by using linearly polarized light.
