Biosensor for Xanthine with Improved Sensitivity and Detection Limit

An interference-free amperometric biosensor for the quantitative xanthine analysis is described. Xanthine was monitored through the electrochemical reduction of hydrogen peroxide (produced upon its enzyme-catalyzed oxidation) at a constant applied potential of -50 mV (vs. Ag/AgCl). The biosensor was designed on the basis of a graphite electrode modified with microquantities of platinum and pall...

Improved sensitivity of wavelength-modulated surface plasmon resonance biosensor using gold nanorods.

In this report, gold nanorods (GNRs) were used to enhance the sensitivity of the wavelength-modulated surface plasmon resonance (SPR) biosensor. The GNRs were designed and fabricated through seed-medicated growth and surface activation by a layer of a weak polyelectrolyte, poly(acrylic acid) for the attaching antibody. Rabbit anti-goat IgG was immobilized on GNRs, and sandwich assays were carri...
