Histopathological aspects of walker 256 tumor using the multifocal technique of inoculation

Magnetic fields have been used to deliver magnetic nanocomposites (MNCs) and alter mechanochemical transduction pathways in malignant tumors. We study mechanoluminescence (ML) of Walker-256 carcinosarcoma cells induced by the magneto-mechanochemical effects of Fe3O4–Au MNCs under a nonuniform rotating magnetic field (RMF). Photoluminescence (PL) and Raman spectra were recorded to investigate the optical response of MNCs. The PL spectrum of MNCs showed three broad emission bands with peaks at 525, 570 and 680 nm. MNCs underwent a phase transition attributed to localized surface plasmon resonance as indicated by the Raman spectra. ML intensity recorded from MNCs[Formula: see text][Formula: see text][Formula: see text]cells[Formula: see text][Formula: see text][Formula: see text]RMF was 3.5 and 1.4 times greater than chemiluminescence (CL) of MNCs[Formula: see text][Formula: see text][Formula: see text]cells and cells alone, respectively ([Formula: see text] 0.05). ML exhibited lesser variation than CL. The nonuniform distribution of a magnetic force exerted on MNCs resulted in more symmetric distributions of ML signals. Therefore, the observed ML emission could originate from the magneto-mechanochemically and light-induced free radical reactions in cancer cells in response to MNCs[Formula: see text][Formula: see text][Formula: see text]RMF. The magneto-mechanochemical effects have the possibility to translate ML to cancer diagnosis and treatment by providing additional information about changes in breaking asymmetry to symmetric processes at the quantum level.
