ljuskänsligljuskänsligt

ljuskänsligljuskänsligt is not a standard term in Swedish. It appears to be a concatenation of two related expressions, ljuskänslig (light-sensitive) and ljuskänsligt (the neuter/adverbial form). In formal Swedish, the separate words are used to describe light sensitivity, and the combined form is unusual in technical or common usage. When discussing light sensitivity, writers typically use ljuskänslig as an adjective or ljuskänsligt as an adverbial or neuter form, depending on grammar and context.

In biology and vision science, ljuskänslighet refers to the ability to respond to light. This includes photoreceptor cells in the retina (rods and cones) and molecular systems such as rhodopsin and photopigments that trigger signaling pathways in response to illumination. Plants also exhibit ljuskänslighet through photoreceptors like phytochromes and cryptochromes that regulate growth and development in response to light.

In materials science and electronics, ljuskänsliga materials change properties when exposed to light. Examples include photoresists used in semiconductor lithography, photoconductive materials, and light-responsive polymers or hydrogels. In photography, light sensitivity is expressed by emulsions and ISO ratings, reflecting how readily the material records light.

Usage notes: to convey light sensitivity in Swedish, favor ljuskänslig (as an adjective) or ljuskänsligt (as an adverbial form). The fused form ljuskänsligljuskänsligt is rarely encountered and may be regarded as a typographical or stylistic error rather than a recognized term.
