Theranostics is a recently emerging area in nanomedicine. Nanoparticles which can combine both diagnostic and therapy in one single platform serve as theranostic agents. Some of the currently explored nanoparticles are metallic nanoparticles, mesoporous silica nanoparticles, carbonbased nanoparticles, and polymer nanogels. Polymeric nanogels are receiving considerable attention due to their high biocompatibility and functional performance. The present review article briefly summarizes the scopes and challenges of the state of art of using polymeric nanogels for theranostic applications. Among the different polymer nanogels, a special emphasis is given to polymeric nanogels with innate imaging potential.

治疗学是纳米医学中的一个新兴领域。可以将诊断和治疗结合在一个平台上的纳米颗粒充当治疗诊断剂。当前探索的一些纳米颗粒是金属纳米颗粒，中孔二氧化硅纳米颗粒，碳基纳米颗粒和聚合物纳米凝胶。高分子纳米凝胶由于其高的生物相容性和功能性能而受到了广泛的关注。本篇综述文章简要总结了将聚合物纳米凝胶用于治疗治疗的最新技术的范围和挑战。在不同的聚合物纳米凝胶中，特别强调具有先天成像潜能的聚合物纳米凝胶。
