Thermal energy conversion

Thermal energy conversion is a thermodynamic process rather than a specific biological molecule, receptor, or therapeutic target. In biological systems, it primarily refers to thermogenesis—the conversion of chemical energy into heat—which is essential for maintaining homeostatic body temperature and regulating metabolic balance [6, 16]. This biological process is often mediated by mitochondrial proteins, most notably Uncoupling Protein 1 (UCP1), which facilitates the leakage of protons across the mitochondrial membrane to generate heat instead of ATP [6, 17]. In modern clinical oncology, this physical principle is harnessed for thermal therapies, such as photothermal therapy (PTT) and magnetic hyperthermia therapy (MHT), where external energy sources like near-infrared light or alternating magnetic fields are converted into localized heat by specialized nanomaterials to ablate tumor cells [1, 5, 12]. Because thermal energy conversion is a physical phenomenon rather than a distinct molecular entity, it is not classified under standard drug target families, though the agents that mediate this conversion are central to hyperthermic and stimuli-responsive drug delivery research [11, 13, 19].
