Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article introduces a novel electrochemiluminescent (ECL) method for detecting sunset yellow (SY) using a polyluminol and polyarginine modified electrode. The method leverages the inhibition effect of SY on the ECL emission of the luminol-H2O2 system, resulting in a decrease in ECL intensity proportional to SY concentration. The GCE/PLu/PLa electrode exhibits excellent ECL response, sensitivity, linearity, selectivity, and reproducibility, making it a promising tool for SY detection in food products. The method was successfully applied to detect SY in soft drinks, demonstrating its practical applicability. Compared to traditional detection methods, this ECL method offers a simpler, more sensitive, and cost-effective alternative.
