A novel molecularly imprinted electrochemiluminescence sensor for isoniazid detection

Abstract: Based on Ru(bpy)(3)(2+)-Au nanoparticles decorated multi-walled carbon nanotubes composites and a molecularly imprinted polymer (MIP), we propose a novel molecularly imprinted electrochemiluminescence (ECL) sensor to selectively determine isoniazid (INH). The MIP is synthesized through electrochemical copolymerization of acrylamide and N,N'-methylene diacrylamide in the presence of INH template molecules. The enhanced ECL intensity is linear in the range of 0.1 to 110 μg cm(-3) and the detection limit is 0.08 … Show more

“…Even if the binding constants of MIP are generally lower than that of antibodies and aptamers, and they have a low electric conductivity, MIP have great chemical and thermal stability and are easy to be prepared. Much effort has been made to develop ECL MIP sensors for pharmaceuticals in recent years [85] , [86] , [87] , [88] , [89] , [90] , [91] , [92] , [93] , listed in Table 5 .…”

“…Until now, many methods for measuring isoniazid have been reported, such as electrochemiluminescence [10,11], electrochemical technology [12,13], performance liquid chromatography [14,15], capillary electrophoresis [16][17][18], spectrophotometry [19][20][21] and liquid chromatography-mass spectrometry [22,23]. Among these methods mentioned, although their doubtless accuracy and effectiveness, the boundedness of these technologies are worth considered, such as difficulty in operation, poor stability, high experimental cost and so on.…”

“…La técnica de la impresión molecular, ofrece grandes posibilidades para el desarrollo de este tipo de polímeros selectivos y puede proporcionar una alternativa válida para el uso de estas fases sensoras.Específicamente, sensores ópticos son aquellos que responden a un cambio en una propiedad óptica (absorción, reflectancia, fluorescencia, fosforescencia, quimioluminiscencia, bioluminiscencia, etc.) que se produce como consecuencia de una variación en la concentración de la especie que se pretende determinar[118][119][120][121][122]. Dentro de los sensores ópticos se puede hacer una clasificación dependiendo del diseño externo: a) Optosensores: también llamados de celda de flujo, son aquellos en los que el sólido ópticamente activo (fase sensora) se encuentra empaquetado en el interior de una celda de flujo que a su vez suele estar en el interior del compartimiento de celdas del sistema de detección (espectrofotómetro, fluorímetro, fosforímetro, etc.…”
