Magneto-Responsive Textile modified by (Nano)Materials

Textiles are materials made by interlocking bundles of yarns or threads The inherent flexibility of the textile materials opens the possibilities for their functionalization. The space between the single fibers and their surface can carry additives of different functionalities, such as magnetic nanoparticles and drug molecules. Magneto-responsive textiles have emerged lately as an important carrier in various applications, including those in biomedical fields such as drug delivery, tissue engineering, and regenerative medicine. We designed and characterized simple woven and non-woven textile materials with magnetic properties that can become potential candidates for a smart magnetic platform for hyperthermia treatments [1]. When heat was induced by magneto-responsive textiles under the influence of a high-frequency alternating magnetic field, the temperature increase in tissue-mimicking phantoms depended on several factors, such as the type of basic textile material, the type of materials used for textile surface modification (magnetic fluids, magnetic Pickering emulsion), and the number of layers covering the phantom. The values of temperature elevation, achieved with the use of magnetic textiles, are sufficient for potential application in magnetic hyperthermia therapies and as heating patches or bandages. Controlled release of substances and/or nano-sized objects from the textiles triggered by high-intensity ultrasound is also possible. This paves the way for the potential use of the proposed textile materials in the theranostics paradigm.<br/>This work was supported by project no. 2019/35/O/ST3/00503 (PRELUDIUM BIS) of the Polish National Science Centre, and project no.
