“…Studies of reversible volume changes in response to pH, ionic concentration, etc. have been carried out for several kinds of polymeric networks [3][4][5]. The swelling behavior of any polymer network depends upon the nature of the polymer, polymersolvent compatibility and degree of cross-linking.…”

Abstract. Hybrid polymeric networks composed of polyacrylamide and chitosan were developed to determine their swelling and ascorbic acid delivery kinetics at various chitosan concentrations. The hybrid acrylamide/chitosan hydrogels were synthesized in aqueous itaconic acid solution (1% w/w). Young's modulus was also evaluated for the hydrogels, and the results were correlated with the swelling properties. Swelling experiments were carried out using three different pH solutions: acidic (pH 4 buffer solution), neutral (distilled water) and basic (pH 10 buffer solution). The results of the swelling study showed that the swelling properties of the network varied with the changes of the pH in the swelling solution, as well as concentration of chitosan. When chitosan concentration increased, the swelling capacity diminished, and therefore Young's modulus increased. The results indicated that the swelling process followed a second order kinetics. The ascorbic acid diffusion inside the hydrogel follows a Fickian mechanism. The ascorbic acid diffusion coefficients are reported as a function of chitosan concentration.

“…Due to attractive features such as a precisely controllable signal amplitude, frequency, and direction, the use of an electric stimulus to trigger hydrogel actuation has aroused remarkable interest 66 . Commonly investigated electric-responsive hydrogels that deform upon electric stimulation include but are not restricted to chitosan [67][68][69] , PAAc 70-73 , 4-hydroxybutyl acrylate (4-HBA) [73][74][75] , and poly(2-acrylamido-2-methylpropanesulfonic acid) (PAMPS) [76][77][78][79] . Chitosan is a natural macromolecular polymer made from chitin, a component abundantly distributed in the shells of crustaceans.…”

The increasingly intimate bond connecting soft actuation devices and emerging biomedical applications is triggering the development of novel materials with superb biocompatibility and a sensitive actuation capability that can reliably function as bio-use-oriented actuators in a human-friendly manner. Stimulus-responsive hydrogels are biocompatible with human tissues/organs, have sufficient water content, are similar to extracellular matrices in structure and chemophysical properties, and are responsive to external environmental stimuli, and these materials have recently attracted massive research interest for fabricating bioactuators. The great potential of employing such hydrogels that respond to various stimuli (e.g., pH, temperature, light, electricity, and magnetic fields) for actuation purposes has been revealed by their performances in real-time biosensing systems, targeted drug delivery, artificial muscle reconstruction, and cell microenvironment engineering. In this review, the material selection of hydrogels with multiple stimulusresponsive mechanisms for actuator fabrication is first introduced, followed by a detailed introduction to and discussion of the most recent progress in emerging biomedical applications of hydrogel-based bioactuators. Final conclusions, existing challenges, and upcoming development prospects are noted in light of the status quo of bioactuators based on stimulus-responsive hydrogels.

“…Numerous investigations conducted on electro-responsive polymers involve polyelectrolyte hydrogels, as they distort in electrical field because of deswelling or anisotropic inflammation when activated ions are steered toward the cathodic or anodic region of the hydrogel. ,− Electro-responsive polymers can be prepared from both synthetic as well as the natural polymers, where naturally occurring polymers include chondroitin sulfate, alginate, chitosan and hyaluronic acid, while synthetic polymers include allylamine, acrylonitrile, vinyl alcohol, 2-hydroxyethyl methacrylate (HEMA), methacrylic acid (MAA), , aniline, acrylic acid, 2-acrylamido-2-methylpropanesulfonic acid, and vinyl sulfonic acids . In an investigation conducted in recent times by Gao et al, wherein they stated on electro-sensitive hydrogel constructed from poly(sodium maleate- co -sodium acrylate) and PVA that the gel distortion amplified on increasing electrical voltage or intensity of NaCl.…”

Over the past few decades, reversible responsive polymer materials have received interest conjointly from academia as well as industry owing to their ability to adapt to the surrounding environment, change adhesion and wettability of copious species upon extraneous stimulus, and regulate transportation of molecules and ions. Stimuli-responsive polymers or macromolecules also exhibit the ability to convert biochemical and chemical signals into mechanical, thermal, optical, and electrical signals, and vice versa, for which they are utilized in an array of applications like “smart” optical systems, drug delivery, diagnostics, and tissue engineering, in conjunction with coatings, textiles, biosensors, and microelectromechanical systems. Extensive exploration on reversible responsive polymeric systems for a variety of engineering functionalities has been done; however, no collection of all the information is available as such. This Review consolidates profuse studies of reversible responsive polymers utilized in an assorted array of functions, inclusive of sensors, drug delivery, smart and self-healing coatings, etc.
