Nanotechnology-based rose Bengal: A broad-spectrum biomedical tool [PDF]

open access: yesDyes and Pigments, 2021
Rose Bengal is an anionic xanthene dye, a derivative of fluorescein, born in the 19th century as a textile dye; to date, it is known primarily in ophthalmology as a diagnostic tool and demonstrated to be promising in the biomedical field.

Excretion of Rose Bengal in Bile

Nature, 1960
THE metabolism of rose bengal has been investigated by us in humans as well as in experimental conditions in animals. When we examined the dye by one-dimensional paper chromatography using 25 per cent ethanol and 5 per cent ammonia (1: 1) as a solvent1, we found it contained several components.

Influence of Rose Bengal Dimerization on Photosensitization

Photochemistry and Photobiology, 2021
AbstractProtein crosslinking photosensitized by rose Bengal (RB2−) has multiple medical applications and understanding the photosensitization mechanism can improve treatment effectiveness. To this end, we investigated the photochemical efficiencies of monomeric RB2− (RBM2−) and dimeric RB2− (RBD2−) and the optimal pH for anaerobic RB2 ...

PROPERTIES OF ROSE BENGAL: (X) NEW DERIVATIVES OF POLYMER‐ROSE BENGAL

Photochemistry and Photobiology, 1985
Abstract— Polymer rose bengal derivatives are converted to their C‐6 ammonium salts. The φ1 O2 derived in CH2C12 is a function of the KB of the neutralizing amine.

Cationic Phosphorus Dendrimer Enhances Photodynamic Activity of Rose Bengal against Basal Cell Carcinoma Cell Lines [PDF]

open access: yesMolecular Pharmaceutics, 2017
International audienceIn the last couple of decades, photodynamic therapy emerged as a useful tool in the treatment of basal cell carcinoma. However, it still meets limitations due to unfavorable properties of photosensitizers such as poor solubility or ...

Phosphazene-bound Rose Bengal: A novel photosensitizer for singlet oxygen generation [PDF]

open access: yesJournal of Inorganic and Organometallic Polymers, 1991
In this paper we report the synthesis and the characterization of cyclo- and polyphosphazenes supporting Rose Bengal. These substrates are suitable for the photosensitized generation of singlet oxygen, both in homogeneous and in heterogeneous phase.

Metabolism of Rose Bengal

Nature, 1962
ROSE bengal has been used for chromo-excretion liver tests usually without a more accurate investigation of the composition of the dye. From the results of Stowe et al.1, it appears that only highly halogenated derivatives of fluorescein are selectively excreted by the liver.

Rose Bengal Strips

American Journal of Ophthalmology, 1979
I prepared rose bengal biological stain from its powder base to a 1% concentration. It was then impregnated into filter paper and allowed to air dry. The filter paper strips were sterilized and stored for individual use.
