The measurement of total bilirubin in serum is one of the most frequently performed tests in clinical analysis. A new spectrofluorometric method was developed for the determination of trace amounts of total bilirubin. Using tetracycline-Eu(3+) as a fluorescent probe, bilirubin can remarkably reduce the fluorescence intensity of the tetracycline-Eu(3+)(More)
Surface oxidation states of ultrafine particulate matter can influence the proinflammatory responses and reactive oxygen species levels in tissue. Surface active species of vehicle-emission soot can serve as electron transfer-mediators in mitochondrion. Revealing the role of surface oxidation state in particles-proteins interaction will promote the(More)
A new spectrofluorimetric method was developed for the determination of trace amounts of lecithin using the ciprofloxacin (CIP)-terbium (Tb3+) ion complex as a fluorescent probe. In a buffer solution at pH = 5.60, lecithin can remarkably reduce the fluorescence intensity of the CIP-Tb3+ complex at lambda = 545 nm. The reduced fluorescence intensity of the(More)
That intense demand for both high sensitivity and high reliability has been a key factor strengthening the surface enhanced Raman spectroscopy (SERS) in the analytical application, particular in the hyphenation with pre-concentration technique. Credible data acquisition and processing is very dependent on the stable and uniform performance of SERS-active(More)
A new spectrofluorimetric method was developed for determination of trace amount of bilirubin. Using oxytetracycline-Eu(3+) as a fluorescent probe, in the buffer solution of pH = 7.3, bilirubin can reduce remarkably the fluorescence intensity of the oxytetracycline-Eu(3+) complex at λ = 612 nm and the reduced fluorescence intensity was in proportion to the(More)
BACKGROUND Lecithin is found throughout biological systems. A new spectrofluorimetric method was developed for the determination of trace amounts of lecithin. METHODS Optimum conditions for the determination of lecithin were investigated. RESULTS Using norfloxacin (NF)-terbium ion (Tb3+) as a fluorescent probe, in a buffer solution at pH=6.80, lecithin(More)
