Abstract: Due to the advantages of large surface area, high loading capacity, good dispersion stability and stimulative responsibility, nanogels have potential applications in various fields like biomedicine, chemical and new material industries. In this review, typical methods for the preparation of nanogels, including the traditional ways like the physical and chemical cross-linking, and the novel approaches such as microfluidics, electrospray and electro-Fenton process, were summarized. The principles, advantages and disadvantages of those methods were introduced. In addition, the important properties of nanogels, such as biocompatibility and degradability, swelling property, and stability were summarized with a focus on their stimuli responsibility. Meanwhile, recent applications of nanogels in drug delivery and release, biosensor, molecular imaging, enzyme immobilization, plasticizer,and water treatment, were also summarized. Considering the problems in the preparation and applications, it was proposed that the studies regarding the new gel matrix, the surface modification and the development of green controllable preparation methods are the potential directions for nanogels in future.
