A scientific article co-authored by representatives of the University of Georgia’s School of Science and Technology has been published in the international scientific journal Nanoscale Research Letters.
The article was prepared with the participation of University of Georgia Associate Professors Lili Arabuli, Dimitri Lashkhi, and Nana Tsiklauri. The research addresses the growing problem of bacterial resistance to antibiotics and explores one alternative approach to combating it: antimicrobial photodynamic therapy.
Antibiotic resistance is one of the major challenges facing modern medicine. As bacteria develop resistance to antibiotics, treating infections becomes increasingly difficult, creating a greater need for alternative treatment methods.
The article examines antimicrobial photodynamic therapy (aPDT), an approach that uses light-sensitive substances activated by light to destroy microorganisms.
Particular attention is given to phthalocyanines, specialized compounds that generate reactive oxygen species (ROS) through interactions between light and oxygen. These reactive particles can damage and destroy bacteria and fungi.
The article also explores how nanotechnology can be used to improve the effectiveness of phthalocyanines, the challenges facing this field, and the prospects for introducing the method into clinical practice.
The paper brings together existing scientific knowledge on phthalocyanine-based photodynamic therapy and evaluates its potential for combating microorganisms resistant to antibiotics.
According to the review, nanotechnology can help improve the delivery, solubility, and effectiveness of photosensitizing compounds. However, the broader clinical application of this method remains limited and requires further research.
Antimicrobial resistance is a global challenge that threatens the effective treatment of infectious diseases. Developing treatment approaches with mechanisms of action different from those of antibiotics is important for creating new therapeutic possibilities.
Photodynamic therapy represents a promising research direction because the reactive oxygen species generated through light activation can simultaneously target different cellular structures of microorganisms. Consequently, this approach could potentially complement existing antimicrobial treatments and contribute to the development of new strategies for combating resistant infections.
