background and objectives: pseudomonas aeruginosa is one of the most important opportunistic pathogens in patients who suffer from immunodeficiency and burns. wound infections caused by p. aeruginosa can rapidly change to systemic and life threatening situation. the aim of this study was to apply florescent in situ hybridization (fish) method for rapid detection of p. aeruginosa in burrn patien...

background and purpose: salmonella is a group of enterobacterias that cause infectious diseases in human and animals. typhoid, bacteremia, enterocolitis and salmonellosis which are caused by this bacterium are considered major health concerns in developing countries, such as iran. quick, accurate, reliable and early diagnosis is vital to prevent salmonella outbreak. materials and methods: there...

Background: The objective of present study was to assess potential of DHR123 (dihydrorhodamine 123) fluorescent probe for measurement of H2O2 produced by human spermatozoa and comparing the results with DCFH-DA (2', 7'-dichlorodihydrofluorescein diacetate). Materials and Methods: Fluorescent intensity and percentage R123 and DCF positive sperm measured by flow cytometry. The suitable ...

in this work, a novel hg2+ sensitive fluorescent chemosensor is constructed. the proposednano-chemosensor was prepared through the preparation of 3-(benzo[d]thiazol-2-yl)-7-hydroxy-2h-chromen-2-one functionalized silica nanoparticles which has high magnetization properties (btc-fe3o4@sio2). theûnal product was characterized by fourier transform infrared spectroscopy (ft-ir), thermal gravimetric...

Based on a change in structure between spirocyclic (non-fluorescent) and ring-open (fluorescent) forms of rhodamine-based dyes, a new fluorescent and colorimetric Cu(2+) probe was designed and synthesized. Upon treatment with Cu(2+), the weakly fluorescent probe exhibited a strong fluorescence response with high selectivity. In addition, the turn-on fluorescent probe upon the addition of Cu(2+)...
