AO/PI staining of AGS cells treated with NCC/CTAB/FA/Quercetin NPs shows concentration-dependent effects. Untreated controls show healthy green fluorescence. At 1 µg/mL, some cells display green and orange/red fluorescence, indicating viability and early apoptosis. At 3 µg/mL, increased orange/red fluorescence suggests late apoptosis or necrosis. At 30 µg/mL, strong orange/red fluorescence indicates significant apoptosis and cell death, demonstrating the therapeutic potential of these NPs for gastric cancer
