“…The findings revealed that the NIDN hydrogel system might be easily changed into a new kind of magnetic reactive hydrogel that supports the cell growth of bone marrow mesenchymal stem cells and has the ability to repair calvarial defects. Zhang et al used self-fabrication of graphene oxide (GO) nanosheets, poly (vinyl alcohol) (PVA) chains, and G-quartet/hemin (G4/H) motifs to create a three-dimensional (3D) supramolecular hydrogel exhibiting stimuli-responsive characteristics in aqueous environments [ 286 ]. The GO/PVA/G4/H hydrogel had a honeycomb-like 3D GO lattice architecture and outstanding mechanical characteristics as it was manufactured.…”

In recent years, smart/stimuli-responsive hydrogels have drawn tremendous attention for their varied applications, mainly in the biomedical field. These hydrogels are derived from different natural and synthetic polymers but are also composite with various organic and nano-organic fillers. The basic functions of smart hydrogels rely on their ability to change behavior; functions include mechanical, swelling, shaping, hydrophilicity, and bioactivity in response to external stimuli such as temperature, pH, magnetic field, electromagnetic radiation, and biological molecules. Depending on the final applications, smart hydrogels can be processed in different geometries and modalities to meet the complicated situations in biological media, namely, injectable hydrogels (following the sol-gel transition), colloidal nano and microgels, and three dimensional (3D) printed gel constructs. In recent decades smart hydrogels have opened a new horizon for scientists to fabricate biomimetic customized biomaterials for tissue engineering, cancer therapy, wound dressing, soft robotic actuators, and controlled release of bioactive substances/drugs. Remarkably, 4D bioprinting, a newly emerged technology/concept, aims to rationally design 3D patterned biological matrices from synthesized hydrogel-based inks with the ability to change structure under stimuli. This technology has enlarged the applicability of engineered smart hydrogels and hydrogel composites in biomedical fields. This paper aims to review stimuli-responsive hydrogels according to the kinds of external changes and t recent applications in biomedical and 4D bioprinting.

The imbalance in generation of reactive oxygen species and its depletion causes oxidative stress. Because of its importance, there is a need to explore the role of oxidative stress biomarkers. The limitations of the conventional methods cause the researchers look for other alternatives. Biosensors are highly promising candidates for the detection of trace quantities for various analytes with high specificity, selectivity, and quick response time. Nanomaterial based matrices are the most popular choice while fabricating a biosensor. Two-dimensional (2D) materials such as graphene, transitional metal dichalcogenides, and various metal oxides have been used for the biosensing of different oxidative stress analytes. High electron mobility, good optical properties, tunable properties, high yields, easy synthesis, and availability make these materials the first choice. In this review, we have comprehensively discussed various biomarkers associated with oxidative stress. The review will provide information related to different kinds and various synthesis procedures employed for 2D nanomaterials. The major focus of the review is to elaborate the role of 2D nanomaterial based structures for the optical and electrochemical methods for the detection of oxidative stress. This review is an effort to help the researchers better understand various 2D based transducers available for the detection of oxidative stress biomarkers.
