Abstract: | Despite extensive research advancements in cancer therapy, the newlinemedical community continues to grapple with formidable challenges in newlinethe treatment and eradication of cancer that accounts for one-sixth of newlinehuman deaths. Newer non-invasive and patient-friendly cancer treatment newlinemodalities are of utmost importance owing to the severe side effects newlineassociated with conventional therapeutic approaches, viz. surgery, newlinechemotherapy, and radiotherapy. Stimuli-responsive drug delivery and newlinemagnetic hyperthermia are two such treatment methods gaining increased newlineclinical attention. The former works on the principle of internal and newlineexternal stimuli-driven release of chemotherapeutics while the latter newlineinvolves artificially elevating the tumour tissue temperature to 41-43 ºC. newlineThis study is focused on the design and development of four customizable newlinestimuli-sensitive drug delivery devices capable of eliciting hyperthermia newlinefor cancer treatment. Superparamagnetic iron oxide nanoparticles (SPIONs), newlinesurface-functionalized with nanocellulose and chitosan, were employed newlinefor formulating these systems where magneto-responsive drug delivery newlineis established with doxorubicin (DOX) as the model drug. Initially, newlinesuperparamagnetic cellulose nanofibers with pH-dependent drug release newlineand hyperthermia potential were prepared by an in situ synthesis (from newlineAgave sisalana plant leaf fibers), for deep-seated chemotherapeutic newlineapplications. Glyoxal crosslinked superparamagnetic and porous chitosan newlinemicrospheres were then designed, which are able to release the drug in newlinea controlled manner via degradation-dependent diffusion. newline |
