The healing power of light has attracted interest for thousands years. Scientific discoveries and technological advancements in the field have eventually led to emergence photodynamic therapy, which soon became a promising approach treating broad range diseases. Based on interaction between light, molecular oxygen, various photosensitizers, therapy represents non-invasive, non-toxic, repeatable...

Antimicrobial photodynamic inactivation (aPDI) employing the BODIPY-based photosensitizer 2,6-diiodo-1,3,5,7-tetramethyl-8-(N-methyl-4-pyridyl)-4,4'-difluoro-boradiazaindacene (DIMPy-BODIPY) was explored in an in vitro assay against six species of bacteria (eight total strains), three species of yeast, and three viruses as a complementary approach to their current drug-based or non-existent tre...

The application of fluorescent II-VI semiconductor quantum dots (QDs) as active photosensitizers in photodymanic inactivation (PDI) is still being evaluated. In the present study, we prepared 3 nm size CdTe QDs coated with mercaptosuccinic acid and conjugated them electrostatically with Zn(II) meso-tetrakis (N-ethyl-2-pyridinium-2-yl) porphyrin (ZnTE-2-PyP or ZnP), thus producing QDs-ZnP conjug...

Chlorophyll has unique physicochemical properties which makes them good as photosensitizer of Photodynamic Inactivation (PDI). The chlorophyll can be optimized through several routes. One the possible route is by replacing metal ion center with other ions. In this research, effect coordinated in natural chlorophyll-a was studied for bacterial growth (S. aureus) inhibition. replacement hopefully...
