“…The shape memory polymers (SMPs) are a special class of smart materials that can be programmed to a temporary shape and subsequently trace its permanent shape when activated with certain stimuli such as heat, [1][2][3][4][5] cooling, [6] solvent, [7] pH, [8][9][10] and light [11][12][13][14] (Figure 1).…”

Solvent responsive shape memory polymers are smart shape morphing materials that can recover from a fixed shape when stimulated with solvents. Unlike thermally responsive shape memory polymers, these materials have numerous unique advantages that enabled them to grab the attention of the scientific community. Since early 2005, with the inception of the solvent-induced recovery process, the shape memory polymer realm continued to evolve to circumscribe this novel stimulus. With this backdrop, this review attempts to highlight the development and the growth of solvent responsive shape memory polymers along with its recent trends. After introducing the concept of shape memory polymers, the review introduces how the idea of solvent-induced shape memory polymer stemmed along with describing how the response behavior works. A variety of polymer systems are introduced that respond to water and various solvents together with their emerging application in biomedicine and typical sensing operations. Finally, the potentials and the future outlook for improvement are reviewed.

“…Polydopamine (PDA) is a biopolymer used for drug delivery due to its biocompatibility, easy polymerization on the surface of particles, and its NIR-sensitive properties [88][89][90][91]. PDA exhibits a strong NIR absorption, which allows for the controlled release of encapsulated particles when irradiated with a laser at 750-1000 nm [25,26]. Wu et al delivered proteins by attaching proteins in a mesoporous PDA delivery system [92].…”

Polymers that can change their properties in response to an external or internal stimulus have become an interesting platform for drug delivery systems. Polymeric nanoparticles can be used to decrease the toxicity of drugs, improve the circulation of hydrophobic drugs, and increase a drug’s efficacy. Furthermore, polymers that are sensitive to specific stimuli can be used to achieve controlled release of drugs into specific areas of the body. This review discusses the different stimuli that can be used for controlled drug delivery based on internal and external stimuli. Internal stimuli have been defined as events that evoke changes in different characteristics, inside the body, such as changes in pH, redox potential, and temperature. External stimuli have been defined as the use of an external source such as light and ultrasound to implement such changes. Special attention has been paid to the particular chemical structures that need to be incorporated into polymers to achieve the desired stimuli response. A current trend in this field is the incorporation of several stimuli in a single polymer to achieve higher specificity. Therefore, to access the most recent advances in stimuli-responsive polymers, the focus of this review is to combine several stimuli. The combination of different stimuli is discussed along with the chemical structures that can produce it.

“…Compared with the limitations of direct thermal initiation in many applications, near-infrared light (NIR), as a remote and precise regulatory stimulus source, can control the photoinduced deformation process, reduce the environmental complexity in the application of shape memory materials, and be more environmentally friendly and convenient. [4][5][6] Common near-infrared-responsive shape memory materials are designed to disperse photothermal-responsive inorganic fillers into a thermal-responsive shape memory matrix. 7,8 For example, Bai 9 reported the preparation of composite materials with a great photothermal shape memory effect by adding graphene oxide (GO) to thermosetting polyurethane (TU).…”
