The unique physiochemical features and varied production techniques of metal-organic framework (MOF) materials have piqued the scientific community's interest in solar cell research. Using MOF can enhance stability photovoltaic performance resulting optoelectronic devices. Recent notable breakthroughs cells using MOFs, such as dye-sensitized (DSSCs), perovskite (PSCs), others, are summarized generalized this study. power conversion efficiency (PCE) for DSSCs reached 7.03% perovskites 25.6% when MOF-based nanomaterials were used recently. goal brief overview is to increase knowledge material characteristics open up new avenues use future.

Antibacterial resistance causes around 1.27 million deaths annually the globe and has been recognized as a top 3 priority health threat. Antimicrobial photodynamic therapy (aPDT) is considered promising alternative to conventional antibiotic treatments. Algal lipid extracts have shown antibacterial effects when used photosensitizers (PSs) in aPDT. In this work we assessed efficiency of lipidic microalgae belonging different phyla (Bacillariophyta, Chlorophyta, Cyanobacteria, Haptophyta, Ochrophyta Rhodophyta). All (at 1 mg mL−1) demonstrated reduction Staphylococcus aureus >3 log10 (CFU mL−1), exhibiting bactericidal activity. Bacillariophyta Haptophyta were top-performing against S. aureus, achieving >6 with light doses 60 J cm−2 (Bacillariophyta) 90 (Haptophyta). The properties Phaeodactylum tricornutum Tisochrysis lutea, best effective extracts, also at lower concentrations (75 μg mL−1, 7.5 3.75 reaching, general, inactivation rates higher than those obtained widely PSs, such Methylene Blue Chlorine e6, concentration dose. presence chlorophyll c, which can absorb greater amount energy chlorophylls b; rich content polyunsaturated fatty acids (PUFAs) fucoxanthin, produce ROS, e.g. singlet oxygen (1O2), photo-energized; lack photoprotective carotenoids β-carotene, low tocopherol, associated algal antimicrobial activity aureus. exhibited by seems result from photooxidation PUFAs 1O2 and/or other ROS produced irradiated chlorophylls/carotenoids, eventually led bacterial peroxidation cell death, but further studies are needed confirm hypothesis. These results revealed potential an unexplored source natural (microalgae extracts) that be PSs aPDT treatments, even combat resistance.
