Microbial infections represent a silent threat to health that has worsened in recent decades due to microbial resistance to multiple drugs, preventing the fight against infectious diseases. Therefore, the current postantibiotic ...

La absorción de luz por una molécula llamada fotosensibilizador (PS) en presencia de oxígeno molecular desencadena la generación de especies reactivas de oxígeno (ROS), que en un medio biológico son capaces de degradar las ...

The antimicrobial photodynamic activity (aPDA) in fungal and bacterial strains of supramolecular adducts formed between the anionic photosensitizer (PS) Rose Bengal (RB2-) and aromatic polycations derived from (p-vinylbe ...

A polymeric photosensitizer based on poly(allylamine hydrochloride) (PAH) and rose Bengal (RB) was synthesized. The modified polycation PAH-RB was demonstrated to be suitable for construction of microcapsules via a ...

Improving the overall performance of photoactive drugs used in Photodynamic therapy (PDT) continues to be an essential goal in this area of research. There are continued efforts from several groups around the world to ...

Photodynamic therapy (PDT) is a modern form of treatment of cancers and other diseases. It is based on the use of a photosensitizer (PS), a molecule that after absorbing light generates reactive oxygen species with the ...

Singlet oxygen (1Dg, or commonly 1O2) is a reactive oxygen species of importance in many biomedical applications, particularly the photodynamic ablation of cancer cells known as Photodynamic Therapy (PDT). In a therapeutical ...
