The first part of the review highlights the high impact of stimuli-responsive hydrogels in materials science. From macro to micro scale, the review also collects the most recent studies on the preparation of hybrid polymeric microgels composed of a nanoparticle (able to respond to external stimuli), encapsulated or grown into a stimuli-responsive matrix (microgel).

Licentiate thesis: Hydrogel based pH-sensors Development and characterization of optical and electrical pH sensors based on stimuli-responsive hydrogels

2018-06-07 · Stimuli-responsive (thermoresponsive) hydrogels are used as drug delivery systems for the controlled release of drugs from functionalized textiles applied for skin care [ 53, 61 ]. 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). Stimuli-Responsive Injectable In situ-Forming Hydrogels for Regenerative Medicines.

Stimuli responsive hydrogels

Real-time monitoring of step-growth polymerization of glycerol was investigated using in-line and off-line Attenuated Total Reflectance/Fourier Transform infrared (ATR-FTIR) technique. Figure 1: Stimuli responsive swelling of hydrogels Potential applications of all types of hydrogels includes: tissue technology, man-made extracellular matrix, biosensor, implantable devices, stuffs commanding the activity of enzymes, phospholipid bilayer destabilising agents, stuffs commanding cell reversible fond regard, nanoreactors and smart microfluidics.

The Handbook is divided into four sections: Stimuli-Sensitive Hydrogels, Hydrogels for Drug Delivery, Hydrogels for Tissue Engineering, and Hydrogels with

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.

The complex tissue‐specific physiology that is orchestrated from the nano‐ to the macroscale, in conjugation with the dynamic biophysical/biochemical stimuli underlying biological processes, has inspired the design of sophisticated hydrogels and nanoparticle systems exhibiting stimuli‐responsive features. Recently, hydrogels and nanoparticles have been combined in advanced nanocomposite …

The abilities of intelligent polymer hydrogels to change their structure and volume phase in response to external stimuli have provided new possibilities for various advanced technologies and great research and application potentials in the medical field. Stimuli-responsive hydrogel membranes coupled with biocatalytic processes. 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.

Stimuli-responsive hydrogels particularly have been widely reported to tune drug release rates for drug delivery. hydrogels have been developed for gene delivery,7 wound healing, 8hemostatic agents, stem cell delivery9 and tissue engineering.10 Despite interesting biological characteristics, these injectable hydrogels lack response to external stimuli to control and release entrapped therapeutics. Alternatively, stimuli-responsive hydrogels are aqueous- hydrogels.36 We have recently reported hydrogels with exceptionally dynamic character by exploiting telechelic block-like copoly-mers with self-complementary ureidopyrimidinone (UPy) units encapsulated within hydrophobic domains.37−40 The hydrogels exhibited strong pH- and temperature-responsive gelation Received: January 8, 2014 Published Stimuli-responsive hydrogels have become popular in medicine and polymer science as useful ‘smart’ devices due to their various properties such as overall biocompatibility, high drug loading capacity, and controlled molecule delivery.
