 Nanogels are a type of hydrogel nanoparticle used in biomedical applications. They offer many benefits including high drug encapsulation capacity, uniformity, tunable size, ease of preparation, minimal toxicity, stability in the presence of serum, and stimuli responsiveness. These properties make them ideal candidates for use in chemotherapy, diagnosis, organ targeting, and delivery of bioactive substances. Additionally, nanogels can be designed with specific features such as swelling capacity, stimuli sensitivity, and great surface area, making them suitable for a variety of applications. Furthermore, recent advancements in nanogel technology have enabled them to be used as carriers of genetic material, proteins, and vaccines. Despite these advancements, there remain challenges associated with the production of nanogels at large scales and their integration into clinical practice.
