Biosensor comprising metal nanoparticles

Abstract

[EN] The present invention discloses a biosensor for visual detection of an analyte, based on the light to heat conversion properties of metal nanoparticles: the analyte is visually detected by the colour change in the support areas (where the analyte is present), produced as a result of the heat generated by the metal nanoparticles where they are irradiated with an external light source. Use of said biosensor in a method for the detection of analytes is also claimed.

[ES] La presente invención se refiere a un biosensor donde la detección del analito se realiza de forma visual por el cambio de color en las zonas del soporte en que el analito esté presente producido por las nanopartículas al ser irradiadas con una fuente de luz externa.
