Superparamagnetic nanoparticle-arrested hydrogel matrices have immense significance in smart soft biomaterials. Herein, we report the synthesis of superparamagnetic nanoparticle-loaded magneto-responsive tough elastomeric hydrogels for dual-responsive drug delivery. In first phase work, carried out room-temperature amine-functionalized iron oxide nanoparticles (IONPs), and second demonstrated that IONPs could act as a toughening agent well viscosity modifier poly(acrylic acid-co-hydroxyethyl methacrylate) copolymer hydrogels. The was tested by Fourier transformed infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), continuous-wave-electron paramagnetic resonance (CW-EPR). Moreover, affect its gelation time elasticity significantly, which also evaluated from rheological behavior. compressive mechanical strength (∼120 kPa), elasticity, recovery to original shape (zero permanent set), water uptake, thixotropic behavior under dynamic stress hybrid supported robustness swelled state. release showed dual parameter dependency (IONPs cross-linker) responsiveness against both pH static magnetic field. delayed network rupturing, delivery nature, noncytotoxic human live cells promote this an ideal alternative remotely controlled vehicle.

Cancer continues to be one of the leading causes death worldwide, and conventional cancer therapies such as chemotherapy, radiation therapy, surgery have limitations. RNA therapy vaccines hold considerable promise an alternative for their ability enable personalized with improved efficacy reduced side effects. The principal approach is induce a specific immune response against cells. However, major challenge in immunotherapy predict which patients will respond treatment monitor vaccine during treatment. Theragnostics, integration diagnostic therapeutic capabilities into single hybrid platform system, has potential address these challenges by enabling real-time monitoring while allowing endogenously controlled adjustments. In this article, we review current state-of-the-art theragnostics including imaging agents, biomarkers, other tools relevant cancer, application development personalization. We also discuss opportunities further clinical translation vaccines.
