The recent FDA Modernization Act removes the obligation of animal testing for new drugs, which has become increasingly futile due to the advancements in more accurate alternatives such as artificial tissue models. These models are routinely constructed using hydrogels, which have an array of biomedical applications. Here, we review some of the most exciting recent applications of hydrogels from the year so far. Under the Federal Food, Drug and Cosmetics Act (FFDCA) of 1938, it was required for new drug and cosmetic products to be tested on animals to evaluate their safety and efficacy. However, nearly eight decades later there...
