Cancer represents a significant societal, public health, and economic challenge. Conventional chemotherapy is based on systemic administration; however, it has current limitations, including poor bioavailability, high-dose requirements, adverse side effects, low therapeutic indices, the development of multiple drug resistance. These factors underscore need for innovative strategies to enhance delivery directly tumours. However, local treatment also presents challenges, penetration through endothelial layers, tissue density in tumour microenvironment, interstitial fluid pressure, physiological conditions within tumour, permanence at site action. Nanotechnology promising alternative addressing these challenges. This narrative review elucidates potential nanostructured formulations cancer treatment, providing illustrative examples an analysis advantages challenges associated with this approach. Among nanoformulations developed breast, bladder, colorectal, oral, melanoma cancer, polymeric nanoparticles, liposomes, lipid nanohydrogels have demonstrated particular efficacy. systems permit mucoadhesion enhanced penetration, thereby increasing concentration (bioavailability) consequently improving anti-tumour efficacy potentially reducing effects. In addition studies indicating chemotherapy, nanocarriers can be used as theranostic approach combination irradiation methods.

A series of dinuclear Ir(III) complexes have been constructed for enhanced photodynamic and photothermal therapy (PDT PTT) cisplatin-resistant non-small-cell lung cancer. They enter cells via caveolar endocytosis, target mitochondria but not nuclear, generate both singlet oxygen superoxide anion, release heat when exposed to infrared (IR) irradiation, thus inducing reactive species (ROS)-associated cell disruption thermal ablation. The IR-generated ROS can further activate caspases, triggering apoptosis. Additionally, the deplete intracellular glutathione, lead lipid peroxidation, induce ferroptosis. selected complex
