Abstract

Fluorescence quantum yields are used to quantify the efficiency of the emission process. In spite of the importance of these data, experimental directions for their acquisition are rarely given. A general procedure for determining the relative fluorescence quantum yield of solutions is described here, drawing attention to the many pitfalls that students may encounter. Starting materials are common yellow and pink highlighter pens.

  Thick-shell CdSe/nCdS (n ≥ 10) nanocrystals were recently reported that show remarkably suppressed fluorescence intermittency or “blinking” at the single-particle level as well as slow rates of Auger decay. Unfortunately, whereas CdSe/nCdS nanocrystal ...

  Chemical Research in Toxicology2012 Article ASAP
  Phenolic toxins stimulate oxidative stress and generate C-linked adducts at the C8-site of 2′-deoxyguanosine (dG). We previously reported that the C-linked adduct 8-(4″-hydroxyphenyl)-dG (p-PhOH-dG) undergoes oxidation in the presence of Na2IrCl6 or ...

  Phenolic toxins and mutagenic diazoquinones generate C-linked adducts at the C8 site of 2′-deoxyguanosine (dG) through the intermediacy of radical species. We have previously reported the site-specific incorporation of these adducts into oligonucleotides ...
