A surfactant type fluorescence probe for detecting micellar growth

Fluorescence of N-acylated dansylamide with a long hydrophobic tail: sensitive response to premicellar aggregation of sodium deoxycholate

“…18 A dansyl derivative of amino-dodecanate was used as a fluorescent probe in molecular assemblies by Gao and co-workers. 19 Thus, although there are various dansyl attached biological compounds and their properties reported in the literature, [18][19][20][21][22][23] surprisingly a simple N-acylated dansyl derivative containing an aliphatic chain (16-carbons) is not found among them. This dansyl derivative would be hydrophobic and non-specific, thereby would be useful for a variety of micro and nano scale heterogeneous media.…”

Making sense of luminescence from GRAS optical probes

“…Intensity increases of $100-fold compared to solution have been observed in microorganized environments such as micelles, liposomes, or inclusion complexes [33,34]. Steady state and time resolved luminescence techniques can thus be used to investigate a wide variety of colloidal characteristics such as droplet shape, size, structure and microviscosity [35][36][37].…”

A novel surfactant-like fluorophore and its probing ability to the aggregation of amphiphilic compounds

“…For future work, we are currently using the fluorescence probe reported in this work and those under development to study the micellization of a wider range ionic and non-ionic surfactants, and the micelle growth [35] in typical surfactant solutions, such as SDS system since morphologically the micelles formed in the system could change from spheres to rods, and then to worms when NaBr is introduced [36]. …”
