“…They are three-dimensional, branched polymers with exceptional water absorption capabilities [ 200 ]. The water absorption characteristic of hydrogels is important, as it allows them to absorb and retain large amounts of water, increasing the contact time between water and antimicrobial agents, thereby enhancing their efficiency in purifying water and ensuring safe drinking water supplies [ 201 , 202 ]. The hydrogel’s stretchability, pliability, and porousness properties are sensitized to its capacity to absorb water [ 203 ].…”

The growing impact of infections and the rapid emergence of antibiotic resistance represent a public health concern worldwide. The exponential development in the field of biomaterials and its multiple applications can offer a solution to the problems that derive from these situations. In this sense, antimicrobial hydrogels represent a promising opportunity with multiple translational expectations in the medical management of infectious diseases due to their unique physicochemical and biological properties as well as for drug delivery in specific areas. Hydrogels are three-dimensional cross-linked networks of hydrophilic polymers that can absorb and retain large amounts of water or biological fluids. Moreover, antimicrobial hydrogels (AMH) present good biocompatibility, low toxicity, availability, viscoelasticity, biodegradability, and antimicrobial properties. In the present review, we collect and discuss the most promising strategies in the development of AMH, which are divided into hydrogels with inherent antimicrobial activity and antimicrobial agent-loaded hydrogels based on their composition. Then, we present an overview of the main translational applications: wound healing, tissue engineering and regeneration, drug delivery systems, contact lenses, 3D printing, biosensing, and water purification.

Sustainability in agriculture can only be achieved by protecting important resources, one of them being water. Availability of water in the soil greatly influences agricultural productivity. Hydrogels play a key role in ensuring water availability and achieving agricultural sustainability. A novel superabsorbent hydrogel was synthesized from Artocarpus heterophyllus Lam seed polysaccharides. The synthesized hydrogel was characterized using Fourier transform infrared spectroscopy, X‐ray diffraction, thermogravimetric analysis, and scanning electron microscopy. Swelling capacity of the hydrogel in different solutions, water retention duration, its influence on the soil water holding capacity (SWHC), and degradation in soil were assessed. The hydrogel absorbs up to 326 g/g and degrades naturally at around 1.4 wt% daily. The hydrogel improved the SWHC by 34% at a concentration of 0.3% w/w. Further pot experiments with black gram (Vigna mungo (L.) Hepper) plants showed that the superabsorbent hydrogel ensured water availability for 35 days and relieved the plants from drought‐induced stress. The data presented here indicates that the synthesized hydrogel can potentially be used as a soil conditioner for the sustained release of water and fertilizer.
