Nanomaterials for Fluorescent Detection of Hemoglobin

Simple fluorescence “turn-off” assay for Congo red using commercial 2-aminophthalic acid

“…[20][21][22] The quantum yield is much higher than those of most NH 2 -BDC-based MOFs [11][12][13][14][15] and other uorescent nanomaterials. 20,[23][24][25][26] Importantly, NH 2 -BDC can be commercially obtained and is cheap, and does not require complicated fabrication procedures. The good photostability and high quantum yield render NH 2 -BDC to be promising in uorescent sensors.…”

“…, † the uorescence lifetime of NH 2 -BDC is 15.6009 ns, and in the presence of 100 mM CR, the uorescence lifetime is 15.2752 ns, indicating that the addition of CR did not obviously alter the uorescence lifetime of NH 2 -BDC. The result conrmed that the uorescence quenching mechanism of NH 2 -BDC caused by CR is IFE 20,25. 3.6 Practical applications of NH 2 -BDC for uorescence detection of CR…”
