Many foods and beverages contain photosensitizers
that absorb specific wavelengths of light, both UV and visible.
According to research data, the leading contact photosensitizers
are sunscreens and topical NSAIDs (24).
Lime juice, wild carrots and parsnip proved to contain photosensitizers
, a chemical which makes human skin sensitive to sunlight.
We've designed and studied solar cells where components of the photosynthetic apparatus are used as photosensitizers
Some antihypertensive drugs that are classified as unknown photosensitizers
"may actually have photosensitizing properties," Ms.
Retinal pigmented epithelial (RPE) cells were used under conditions that mimic oxidative stress in the human retina, such as generation of hydrogen peroxide during phagocytosis, hyperglycemia, and in the presence of photosensitizers
Flavonols are most versatile naturally occurring plant components that are generally photochemically inert as indicated by their reported use as photosensitizers
, photoquenchers and ultraviolet absorption filters.
The global drug device combination products market segmentation is based on device types (drug eluting stents, coronary stents, peripheral vascular stents, infusion pumps, implantable infusion pumps, ambulatory infusion pumps, photosensitizers
, orthopedic combination products, antibiotic bone cement, bone graft implants, wound care combination products, antibiotic wound care products, inhalers, nebulizers, metered dose inhalers, dry powder inhalers, transdermal patches, intraocular implants, drug eluting beads).
To achieve this goal the NANOGUARD2AR project will explore the use of nanomaterials (NMs) as photosensitizers
coupled with advanced air-curtains technology and innovative interactive dark operating oxidizing composite materials being able to generate adsorbed hydroxyl radicals without any external energetic excitation.
Tissues with pathological changes can selectively absorb and store photosensitizers
that are activated to produce reactive oxygen species upon excitation at specific wavelengths.
Commercially available solvents and the photosensitizers
rose bengal disodium salt (RB) and methylene blue (MB), were used without any additional treatment.
2]) is an electronically excited form of oxygen which is well known to be formed when photosensitizers
such as chlorophyll or the aromatic dye rose bengal absorb light energy and transfer some of that energy to molecular oxygen [1,2].
