Resum

La incorporació de nanomaterials en sensors basats en materials compostos ha portat a grans avenços en el camp de la química analítica, gràcies a les extraordinàries propietats que ofereixen aquests materials. Els nanodiamants (ND) són un nou tipus de material que ha atret molta atenció perquè es poden produir a gran escala mitjançant metodologies sintètiques relativament econòmiques. A més, els ND poden presentar altres característiques interessants com ara la fluorescència, gràcies a la funcionalització superficial i la biocompatibilitat demostrada, cosa que els fa adequats per a aplicacions biomèdiques. A més, els ND es poden personalitzar amb nanopartícules metàl·liques (NP) com ara plata o or, per combinar les característiques d'ambdues coses. Els ND crus s'utilitzen com a modificadors de sensors gràcies a l'efecte electrocatalític de les espècies oxigenades i 2 sp que es troben en la superfície. L'objectiu d'aquest treball de recerca és avaluar l'aplicabilitat dels ND modificats amb nanopartícules d'or (Au@ND) o plata (Ag@ND) per al desenvolupament d'una plataforma adequada de detecció. Es va dur a terme una caracterització morfològica i electroquímica completa en funció de la composició del material compost preparat, per tal de millorar les propietats electroanalítiques dels sensors desenvolupats. En aquest treball, es va obtenir un resultat òptim amb la 3 5% d'Au@NDs i 1% d'Ag@NDs. Es van obtenir bons resultats en l'avaluació del material compost (bio)sensible basat en grafit-epoxi-Ag@NDs (17:82:1).

abstract = "The incorporation of nanomaterials on (bio)sensors based on composite materials has led to important advances in the analytical chemistry field due to the extraordinary properties that these materials offer. Nanodiamonds (NDs) are a novel type of material that has raised much attention, as they have the possibility of being produced on a large scale by relatively inexpensive synthetic methodologies. Moreover, NDs can present some other interesting features, such as fluorescence, due to surface functionalization and proved biocompatibility, which makes them suitable for biomedical applications. In addition, NDs can be customized with metallic nanoparticles (NPs), such as silver or gold, in order to combine the features of both. Raw NDs were used as modifiers of sensors due to the electrocatalytic effect of the sp2 and oxygenated species present on their surface. The aim of this research work is evaluating the applicability of NDs modified with silver (Ag@NDs) and gold (Au@NDs) nanoparticles for the development of a suitable (bio)sensing platform. A complete morphological and electrochemical characterization as a function of the prepared nanocomposite composition was performed in order to improve the electroanalytical properties of the developed (bio)sensors. In the present work, the optimal composition for Au@NDs present on the nanocomposite matrix is 3.5\% and the one for Ag@NDs is 1\%. Good results were obtained in the evaluation of the optimal composition towards hydrogen peroxide and glucose as a model analyte using a (bio)sensor based on graphite-epoxy-Ag@NDs (17:82:1).",
