“…They were corrected for the yield of NMA as determined by fluorescence spectroscopy after the reaction (12) as well as for self-absorption (11). Since the CL of both luminol and the Luc reaction falls in the same spectral region, no correction was made for the photomultiplier's spectral response (25).…”

The feasibility of using aqueous surfactant micelles to Improve analytical chemiluminescence (CL) measurements was examined. Specifically, the lucigenin (Luc)-Af-methylacrldone CL system was characterized in different micellar and homogeneous media and the effects of various micellar systems upon the CL determination of biological reductants using Luc were assessed. It was found that solubility problems are obviated If the Luc CL assay is conducted In aqueous micelles. Additionally, the presence of cationic or zwltterionlc micelles Improves the sensitivity of the Luc CL assays for ascorbic acid, uric acid, glucose, and fructose by factors of 1.8-4.0. The average precision of the measurements Is ~9% In the micellar media while the accuracy Is comparable to that obtained In water alone. In a few Instances, potential problems due to mutual interference from other reductants can be eliminated via use of micelles. A brief prospective on the general applicability of mlcellar-enhanced CL In chemical analysis Is given.

“…Energy transfer has been observed in several chemiluminescence systems − and surfactants have been shown to enhance emission from chemiluminescence reactions, − but neither has been investigated with respect to contributions of energy transfer mechanisms. Understanding the factors influencing these contributions would be useful for designing chemiluminescence measurements, optimizing sensitivity, and interpreting data.…”

The first study of intermolecular energy transfer processes in a chemiluminescence system is reported. Energy transfer in the acridinium−hydrogen peroxide chemiluminescence system, observed for the first time, is evaluated for radiative, dipole−dipole, and collisional components in the presence and absence of micelles: cetyltrimethylammonium bromide, Brij-35, and sodium lauryl sulfate. In surfactant solutions, the major components were found to be radiative and collisional. Changing the surfactant had the greatest effect on the dipole−dipole component. Effects can be attributed to ion−ion forces, the mixing process, and the path length of the chemiluminescence measurement. In contrast to photoexcited energy transfer studies, the Rhodamine 110 (acceptor) concentration is varied by almost 4 orders of magnitude and is up to 105 greater than the acridinium (donor) concentration. This can be attributed to the absence of excitation absorption in a chemiluminescence measurement and the increased solubility due to the surfactants. The semiempirical method used for evaluating energy transfer should be adaptable to other systems and requires only the spectra of the donor and acceptor and the measurement of chemiluminescence intensity as a function of acceptor concentration.
