Functional polymers capable of being detected by MRI have therefore become attractive, offering the unique advantage of pre-design due to their chemical flexibility, structural diversity, and tailoring of properties. Reversible addition-fragmentation chain-transfer (RAFT) polymerization is a powerful tool that not only enables the precise formation of macromolecular building blocks with complex structures and functions, but also provides a direct method for preparation of polymeric nanoparticles with multiple morphologies suitable for biomedical applications. In addition, when combining RAFT polymers with inorganic/metallic complex nanocomposites, the polymer provides the ability to encapsulate therapeutic molecules, thereby combining diagnostic and therapeutic functions in what is known as a theranostic nanomedicine. In this review, we highlight recent advances in the development of multifunctional polymers as MRI CAs designed and prepared by RAFT polymerization and their performance in diagnosis and treatment of disease.

Since there are many scientific issues that are not well understood yet regarding the working mechanism and fundamental issues regarding the role of polymers in TENGs, this review covers TENG fundamentals and effects of environmental parameters and provides a deep analytical analysis of important literature studies of TENGs. Although TENGs generate high voltage, their current generation is usually in the microamp range. Modifying polymer dielectric materials<span><span> has been much investigated to enhance the output performance of TENGs. This article provides a comprehensive review of various polymer modification categories and associated performance enhancement with an analysis and comparison of research results to help grasp the big picture on the role of polymer modification on TENG performance. Specifically, the source of triboelectrification and updated knowledge about their working principle, and the quantified comparison of triboelectric material are discussed. Then physical nano and microstructure and the effect of TENG material shape on the output are brought into the discussion. Equally, the important role of chemical modification of triboelectric active polymer by way of categorization of methods and their effect on electricity generation is put under focus. In order to enhance the triboelectric negativity of polymer properties, it is useful to introduce chemical groups with high negativity, such as halogens. This can be achieved through several methods, including using a sulfur backbone or casting fluorinated self-assembly monolayers (SAMs), and the impact on TENGs' performance is explored.
