Polyglycerol-based hydrogels from biodegradable raw materials were synthesized by crosslinking reactions of polyglycerol with citric and fatty acids. Three hydrogels were studied varying molar ratios of crosslinking agent. It was found that crosslink amount, type, and size play a crucial role in swelling, thermal, mechanical, and stimuli-responsive properties.

2. Implantable Hydrogels. Implantable hydrogels are 3D stable hydrogels, in which the polymeric chains (natural or synthetic) of hydrogels are cross-linked by … 2017-08-03 Abstract: Among modern drug formulations, stimuli-responsive hydrogels also called “smart hydrogels” deserve a special attention. The basic feature of this system is the ability to change their mechanical properties, swelling ability, hydrophilicity, bioactive molecules permeability, etc., influenced by various stimuli, such as temperature, pH, electromagnetic radiation, magnetic field and biological factors. Polyglycerol-based hydrogels from biodegradable raw materials were synthesized by crosslinking reactions of polyglycerol with citric and fatty acids.

Multi-stimuli responsive hydrogels are instrumental in achieving site-specific delivery of chemotherapeutics to improve drug efficacy and limit toxic side-effects. Hydrogels based on the hydrophobic amino acid residues L-phenylalanine and L-valine were incorporated with magnetic nanoparticles for the site-specific delivery of the can-cer therapeutic doxorubicin (DOX) [77].

Tokarev I, Gopishetty V, Zhou J, Pita M, Motornov M, Katz E, Minko S. A nanostructured signal-responsive thin hydrogel membrane was coupled with enzyme-based systems to yield "smart" multisignal-responsive hybrid systems with built-in "logic". Finally, special attention is focused on a new generation of functional stimuli-responsive polymer hydrogels able to self-shape (shape-memory) and/or self-repair. This last functionality could be considered as the closing loop for smart polymeric gels. 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.

From this context, stimuli-responsive hydrogels are highly attractive as surrogate materials that can simulate dynamic physical microenvironments in vivo.

Thereby, drug delivery systems from hydrogels of stimuli-responsive polymers are being developed for textile-based transdermal therapy [ 61 ]. Based on their responsiveness to external stimuli, the natural polymer-based hydrogels can be classified into the temperature-responsive hydrogel, pH-responsive hydrogel, light-responsive hydrogel, electricresponsive hydrogel, redox-responsive hydrogel, enzyme-responsive hydrogel, magnetic-responsive hydrogel, multi-responsive hydrogel, etc. (2015).

Thermo-Responsive Hydrogels for Stimuli-Responsive Membranes Did you guys get an Acura USB 5000 mAh battery pack in the . Stimuli-responsive conductive hydrogels have emerged as a new rising concept in the hydrogel research field due to their combined advantages of stimuli-responsivity and conductivity from conductive polymers (such as polyaniline, polypyrrole, and polythiophene), carbon nanomaterials (such as carbon nanotubes, graphene and graphene oxide), metals (such as Au and Ag), and conductive ionic compounds (such as Fe 3+ and Al 3+).

In addition, stimuli-sensitive hydrogels have the unique property of undergoing abrupt volume changes from their collapsed and swollen states in response to environmental stimuli, which have both sensor and effector functions.

Stimuli-responsive hydrogels are a class of materials that undergo a chemical transformation—and subsequent expansion or contraction—under the influence of a specific external stimulus. Keywords: smart hydrogels, stimuli-responsive hydrogels, controlled release, drug delivery systems, anticancer drug delivery systems Introduction The first mention of hydrogels appeared in the literature at the beginning of the 19th century; they have been described as colloidal gels derived from inorganic salts.
