Did you know that there are materials that have a great love for water, but which are also characterized by the trait of extreme curiosity, so that they cast their polymer network on various scientific disciplines, from medicine and pharmacy to material science to environmental protection? We are talking about hydrogels, materials that can be smart and sensitive to various external factors, and which radiate their popularity for more than half a century. Soft contact lenses based on hydrogels, various medical implants, disposable diapers, rubbers that swell in contact with water and gels that are used to extinguish fires are just some of the products of the reaction in which hydrogels have undergone certain changes, while preserving their super properties. They spend short breaks from the hectic pace of life in flower vases and helping plants survive dry periods. The future is uncertain, but with such companions of science, it is worth waiting and analyzing.
