Abstract Cytosine plays a preeminent role in DNA methylation, an epigenetic mechanism that regulates gene expression, the misregulation of which can lead to severe diseases. Several methods are nowadays employed for assessing the global DNA methylation levels, but none of them combines simplicity, high sensitivity, and low operating costs to be translated into clinical applications. UV Resonant Raman measurements at excitation wavelengths of 272 nm, 260 nm, 250 nm, and 228 nm have been carried out...

Abstract Pathogenic strains of bacteria are causing various illnesses all around the world and have a major socio‐economic impact. Thus, fast and low‐cost methods for the microbial control of foods are needed. One of them might be photosensitization. This study looks deeper into the mechanism of E. coli damage by Chlorophyllin‐based photosensitization. Fluorimetric data indicate that after 15 min incubation with chlorophyllin (Chl) (1.5 × 10−5 M Chl) 0.73 ± 0.03 μM of this compound was associated...
