Photodynamic Method Boosts Antibiotics Against Drug-Resistant Bacteria
SÃO CARLOS, Brazil, Jan. 8, 2024 — Multidrug-resistant bacteria are considered a serious threat to infection control. Faced with the increasing difficulty of developing new antibiotics to combat resilient bacterial strains, scientists are turning to photodynamic inactivation (PDI), a light-based approach to breaking antimicrobial resistance. PDI strengthens the effect of antibiotics and induces oxidative stress in microorganisms through the interaction of light with a photosensitizer. The photosensitizer is energized in
Modified Antibodies Boost Photodynamic Therapy’s Efficacy
COLLEGE STATION, Texas, May 25, 2021 — Adding antibodies to photodynamic therapies can bolster their efficacy, according to research conducted by Texas A&M University and the University of São Paulo. The work reviewed the existing approaches to photodynamic therapies and...
Updated PDT Targets, Destroys Cancer Cells
BETHESDA, Md., Nov. 18, 2011 — A new form of photodynamic therapy dubbed photoimmunotherapy, or PIT, destroys cancer cells in mice without harming surrounding normal tissue. This light-based cancer therapy technique could theoretically work against tumors in humans, such as those...
