Abstract

Un biosensor en forma de una tira. En una forma de realización, dicha tira biosensora comprende un soporte de electrodo, un primer electrodo, es decir, un electrodo de trabajo, un segundo electrodo, es decir, un contraelectrodo, y un tercer electrodo, es decir, un electrodo de referencia. Cada uno de los electrodos se dispone sobre el soporte de electrodo y se sostiene mediante el mismo. Cada uno de los electrodos está separado de los otros dos electrodos. La tira biosensora puede incluir una capa de cobertura, que define un espacio cerrado sobre los electrodos. Dicho espacio cerrado incluye una zona donde un analito en la muestra reacciona con reactivo(s) depositado(s) en el electrodo de trabajo. Dicha zona se denomina la zona de reacción. La capa de cobertura tiene una abertura para recibir una muestra que se introduce dentro de la zona de reacción. La tira biosensora también puede incluir por lo menos una capa de malla que se interpone en el espacio cerrado entre la capa de cobertura y los electrodos en la zona de reacción. Dicha capa de malla facilita el transporte de la muestra hasta los electrodos en la zona de reacción. En otra forma de realización, se puede construir una tira biosensora para proporcionar una configuración que permite introducir la muestra en la zona de reacción por acción de la fuerza capilar. En dicha forma de realización, se puede omitir la capa de malla. También proporciona un método para determinar la concentración de glucosa en una muestra de sangre completa utilizando el biosensor de la presente.
