Abstract

La presente solicitud se relaciona con una masa de recubrimiento reactiva la cual puede ser utilizada en recubrimiento por extrusion de materiales de soporte planos en procedimientos de fabricacion de tiras de prueba. Ventajosamente, la masa de reactivo de la invencion presenta ciertas propiedades reologicas superiores tales como viscosidad, tension superficial y tixotropia. El reactivo tipicamente comprende una enzima, un radiador redox y modificadores de viscosidad y espesantes, por ejemplo goma de xantano, silice, carboximetilcelulosa y tensioactivos que proporcionan entre 70 y 130 mPa.s y una tension superficial entre 30 y 50 Nm/m. La masa de reactivo preferiblemente se utiliza para recubrir bandas delgadas, estrechas y homogeneas de material reactivo sobre un material de membrana plana.
