A “turn-on” fluorescent sensor for ozone detection in ...

A “turn-on” fluorescent sensor for ozone using bovine serum albumin-directed gold nanoclusters (BSA-Au NCs) via energy transfer was developed. The spectral overlap of fluorescent spectrum of BSA-Au NCs with absorption spectrum of indigo carmine (IDS) was utilized. Ozone cleaves C = C bond of IDS and suppresses energy transfer from BSA-Au NCs to IDS. Therefore, this proposed fluorescent ...

Time-Insensitive Fluorescent Sensor for Human Serum ...

· The on–off fluorescent sensor can readily be available via a one-step chemical synthesis. 23 The assay protocol is simple, with a fluorometer or fluorescence plate reader as the only instrument. The method is not time sensitive, an advantage for potential high throughput screenings and reproducibility. We previously reported a fluorescence method to detect ozone in biofluid samples. …

Highly Sensitive Fluorescent Method for the Detection of ...

· It has been suggested that 1b is preferentially formed by ozone and 1a is preferentially formed by singlet molecular oxygen. In this study we describe the use of 1-pyrenebutyric hydrazine (PBH) as a fluorescent probe for the detection of cholesterol aldehydes. The formation of the fluorescent adduct between 1a with PBH was confirmed by HPLC-MS ...

Fluorescent Sensor for Ozone. | Leading Edge Only

This sensor can detect ozone in the air, in serum, and in pH 7 buffer at 24 to 37 °C by indicating bright fluorescent green. Fluorescent compounds exhibit a fluorescence signal only when the phenolic hydroxyl group is deprotenated. By starting with commercially available 2,7-dichlorofluorescein a two step synthesis of a non-fluorescent compound was prepared by addition of a 1-butenyl group ...
