Abstract
Hoy en día una de las mayores preocupaciones de los consumidores es la contaminación de los alimentos tanto por contaminantes de origen microbiológico como químico, debido a la gran cantidad de efectos secundarios nocivos que generan estos en los seres vivos. Uno de los mayores contaminantes alimenticios que existen son las micotoxinas producidas por los hongos y que normalmente se encuentran omnipresentes en una amplia gama de productos y piensos y que causan efectos altamente tóxicos (cancerígenos, mutagénicos, teratogénicos, estrogénicos, …)1. Debido a esto existe una continua investigación para poder profundizar en las fuentes de contaminación y en las formas de prevenirlas.2De aquí que los polímeros de impronta molecular (MIPs) estén recibiendo una gran atención, ya que son materiales que permiten reconocer de forma específica y selectiva una gran variedad de analitos al igual que los receptores biológicos. Los MIPs poseen mayor estabilidad, robustez y versatilidad que los receptores de tipo biológico. Aunque presentan algunos inconvenientes como la limitación de reconocimiento en medios acuosos, problemas de reactividad cruzada en compuestos estructuralmente semejantes y tiempos de incubación ciertamente elevado siguen siendo unos materiales con cualidades excelentes...
Nowadays, one of the major concerns of consumers is the contamination of foodstuffs by both microbiological and chemical contaminants, due to the large number of harmful side effects they have on living organisms. One of the major food contaminants are mycotoxins produced by fungi which are normally omnipresent in a wide range of products and animal feed, and which cause highly toxic effects (carcinogenic, mutagenic, teratogenic, estrogenic, ...) 1. Due to this, there is continuous research into the sources of contamination and ways to prevent them. Molecularly imprinted polymers (MIPs) are therefore receiving a great deal of attention, as they are materials that can specifically and selectively recognize a wide variety of analytes in the same way as biological receptors. MIPs are more stable, robust, and versatile than biological receptors. But although they have some drawbacks such as limited recognition in aqueous media, problems of cross-reactivity in structurally similar compounds and certainly long incubation times, they are still excellent materials with excellent qualities...
