Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

A form of non-associative learning in which a strong or repeated stimulus makes an organism react more strongly to later stimuli, the opposite of habituation, where a response fades with repetition. Pinsker, Hening, Carew, and Kandel's 1973 Long-term sensitization of a defensive withdrawal reflex in Aplysia showed that a noxious shock to a sea slug enlarged and prolonged its protective reflex for days, and that this change reflects lasting strengthening at specific synapses. The referent is a heightened behavioural and neural response after stimulation, not an immune system learning to attack an allergen or a material being made to absorb more light.[1]
The process by which the immune system, on first encountering an otherwise harmless substance, produces allergen-specific IgE antibodies that bind to mast cells and basophils, so that a later exposure to the same allergen triggers an allergic reaction. Gould and Sutton's 2008 review IgE in allergy and asthma today describes how this IgE-based priming underlies the immediate hypersensitivity seen in conditions such as hay fever, asthma, and food allergy. The referent is a primed immune state specific to an allergen, detected by skin or blood tests, and it is distinct from a nervous system amplifying a reflex or a light-sensitive material being extended to new wavelengths.[2]
The process of making a material respond to light, or to wavelengths of light, that it would otherwise ignore, usually by attaching a dye that absorbs those wavelengths and passes the captured energy to the material. O'Regan and Grätzel's 1991 A low-cost, high-efficiency solar cell based on dye-sensitized colloidal TiO2 films showed that a dye coating lets titanium dioxide, which by itself absorbs only ultraviolet, harvest visible sunlight and generate current. The referent is a physical extension of a material's spectral response, measured in the laboratory, and it has nothing in common with a reflex growing stronger or an immune system priming against an allergen.[3]
