Exploiting poly(safranine) and poly(luminol) for sensing applications. A mini review

Abstract

Safranine and luminol having a unique polymeric constructor combined with different nanomaterials were explored as sensors for different analytes through electrochemical and chemical techniques.

Development of poly(safranine-co-phenosafranine)/GNPs/MWCNTs nanocomposites for quartz crystal microbalance sensor detection of arsenic (III) ions

“…Among these dyes, safranine is a red, phenazine-type dye with an electron donor group (NH 2 ) and a wide heterocyclic conjugated system. Safranine, phenosafranine dyes and their polymeric form are widely employed in various studies, including the pharmaceutical industry, biological, and electrochemical sensors [21][22][23]. However, there is limited research on the electrochemical properties of polymeric safranine [21].…”

“…Safranine, phenosafranine dyes and their polymeric form are widely employed in various studies, including the pharmaceutical industry, biological, and electrochemical sensors [21][22][23]. However, there is limited research on the electrochemical properties of polymeric safranine [21]. Although some studies have investigated the electrochemical applications of poly(safranine) in the sensor domain using the electrochemical polymerization film method, only a few articles are available on chemical oxidative polymerization [24].…”

Sensitive Cr3+ sensor based on novel poly(luminol-co-1,8-diaminonaphthalene)/CeO2/MWCNTs nanocomposites

“…This positively impacts the electrochemical properties of poly(luminol) and its potential use in electrochemical and biosensor materials. [5][6][7][8][9][10] From the same family, a new type of multifunctional polymer material, poly(di-aminonaphthalene), can be synthesized from aromatic diamines, such as 1,5-, 1,8-, or 2,3-diaminonaphthalene, through electrochemical or chemical oxidative polymerization with properties similar to those of polyaniline and polypyrrole. 11 The substance 1,8-diaminonaphthalene displays properties such as electroconductivity, electrocatalysis, electroactivity, permselectivity, electrochromism, and other properties that stem from the chemical reactivity of the functional amino groups on its macromolecular structure.…”

Development of an efficient electrochemical sensing platform based on ter-poly(luminol-o-anisidine-o-toluidine)/ZnO/GNPs nanocomposites for the detection of antimony (Sb3+) ions

“…31,32 The amino group in the luminol structure functions as an electron-donating group in the system and positively impacts the electrochemical properties of poly(luminol) and its potential use in electrochemical and biosensor materials. 33–38 Numerous homopolymers and copolymers of luminol have been reported, including poly(luminol- co -aniline), 39 poly(luminol- co-o -anisidine), and poly(luminol- co -phenylenediamine). 40,41…”
