This study provides a new fabrication method for microelectrode and microbiosensor arrays capable for the first time to retain the activity of the enzymatic system after processing by pulse laser ablation.

Recent Advances in the Fabrication and Application of Screen-Printed Electrochemical (Bio)Sensors Based on Carbon Materials for Biomedical, Agri-Food and Environmental Analyses

“…This suggests that integration of the biological components into the ink formulation is a possible way forward. We recently described the fabrication of a novel screen-printed glucose microbiosensor array using ultrafast pulsed laser ablation following the deposition of screen-printing ink containing the enzyme, glucose oxidase [179]. It should be feasible to adopt a similar strategy for the development of many other biosensors by incorporating appropriate enzymes into a suitable ink formulation.…”

Fabrication of Miniaturised Screen‐printed Glucose Biosensors, Using a Water‐based Ink, and the Evaluation of their Electrochemical Behaviour

“…This suggests that radial diffusion is dominant and is indicative of microband behaviour, rather than being controlled by the rate of the reaction of hydrogen peroxide with cobalt phthalocyanine, or the electron transfer reaction from cobalt phthalocyanine to the carbon electrode. Furthermore, it should be mentioned that, in previous work , voltammetric peaks have been observed with hydrogen peroxide, using electrodes comprised of the water based inks containing cobalt phthalocyanine. This behaviour was observed when either a conventional sized electrode (3 mm×3 mm) was employed, or where diffusion layers overlapped with microelectrode arrays.…”
