A flexible substrate electrochemical biosensor was successfully printed on a polyethylene terephthalate (PET) film with silver (Ag) electrodes using silver nanoparticle based ink. The electrochemical impedance spectroscopy (EIS) response of the printed sensor for detecting low concentrations of bio/chemical species revealed a very high sensitivity at pico molar (pM) concentration levels of D-Proline,...
An impedance based electrochemical biosensor was designed and fabricated for the detection of various chemical and biological species, with glass as substrate material and gold electrodes. A flow cell with inlet and outlet ports for the micro fluidic chamber was designed and fabricated using an acrylic material with a reservoir volume of 78 ??l. The feasibility of the fabricated sensor for detecting...
Characteristics of cadmium ion-selective electrode made cadmium sulphide (CdS)-silver sulphide (Ag 2 S) mixture were studied. CdS-Ag 2 S mixtures were obtained by gas/solid-phase reaction between silver-cadmium mixed powder and hydrogen sulphide gas (dry method) and by ionic reaction between cadmium-silver mixed ions and sulphide ion (wet method). As a result, it was found that the...
