Basically, this study was carried out in the context of the development of ferrogel-based biocompatible soft tissue implants, in particular, for the needs of regenerative medicine and replacement therapy. The magneto-deformation effect (MDE) of ferrogels (FGs) and the possibility of its visualization with the use of medical ultrasound were in the focus of this work. The aim of this investigation was addressed to search a possible relationship between the extent of MDE and the intensity of the reflected echo signal at the gel/water interface and in the gel interior. Cylindrical FGs mm in diameter and mm in height based on polyacrylamide (PAAm) with interpenetrating physical network of natural polysaccharide (Guar) filled with 200–300nm Fe₃O₄ magnetic microparticles (MPs) with weight fraction of 12% or 23% were investigated. MDE was studied using an ultrasonic medical device Sonoline Adara (Siemens …
