Abstract: The present invention concerns a method for detecting and/or quantifying a metal element in a biological liquid, in particular selected from the group consisting of blood, plasma and serum, comprising the steps of: contacting the biological liquid with at least one fluorinated acid substance; applying the biological liquid and the fluorinated acid substance to an electroanalytical sensor; and detecting by means of the electroanalytical sensor a current signal proportional to the amount of metal element in the biological liquid.

Abstract: Fire present invention relates to new electrochemical probes for the measure of an analyte selected from the group consisting of: free chlorine, chlorine dioxide, total chlorine and peracetic acid; characterized in that said probe includes at least a printed electrode nano- or micro-structured whit a nano- or micromaterial selected from the group consisting of: nano- or microparticies of carbon black and/or nano- or microparticles of a metal selected from the group consisting of gold, silver, platinum, copper and combinations or alloys thereof.

Abstract: The present invention relates to a method for functionalising a cellulose support with metal nanoparticles comprising the steps of: depositing on the cellulose support a single aqueous solution containing the metal precursor in the form of acid or salt in a concentration from 1 to 6 mM; and placing the cellulose support at a temperature from 65° C. to 80° C. for a time from 10 to 40 minutes. The present invention also relates to a method for producing an electroanalytical sensor comprising said functionalised cellulose support with electrocatalytic and concentration properties of the metal marker at the working electrode and to a method for producing the electroanalytical sensor.
