This paper presents a microfabricated Clark-type sensor which exactly can measure dissolved oxygen in the cell containing solution. We designed and fabricated a microfabricated Clark-type sensor for measuring the oxygen respiration level of few cells. The microfabricated Clark-type sensor is composed of 3-electrodes on a glass substrate, a FEP (Fluorinated(More)
The characteristics of impedance for the electrode-electrolyte interface are important in the electrode researches for biomedical applications. So, the equivalent circuit models for the interface have been researched and developed. However, the applications of such previous models are limited in terms of the frequency range, type of electrode or(More)
This paper describes a glucose biosensor based on glucose oxidase (GOx) immobilized on porous ZnO/Au electrodes. The ZnO porous electrodes were fabricated by electrochemical deposition of zinc oxide on patterned Au electrodes using polystyrene (PS) spheres as templates. Uniform pore size and highly ordered ZnO pore arrangement were observed from SEM images.(More)
This paper presents the fabrication and characteristics of a new aptamer-based electrochemical immunosensor on the patterned zinc oxide nanorod networks (ZNNs) for detecting thrombin. Aptamers are single-stranded RNA or DNA sequence that binds to target materials with high specificity and affinity. An antibody-antigen-aptamer sandwich structure was employed(More)
This paper presents a microfabricated 2 × 3 array oxygen sensor integrated with heaters and temperature sensors for measuring cellular respiration level in a solution containing cells. The proposed oxygen sensor consists of 2 × 3 array Clark-type sensors, heaters, and temperature sensors on the substrate. Pt was used for temperature sensors,(More)
This paper presents an immunosensor fabricated on patterned zinc oxide nanorod networks (ZNNs) for detecting the H1N1 swine influenza virus (H1N1 SIV). Nanostructured ZnO with a high isoelectric point (IEP, approximately 9.5) possesses good absorbability for proteins with low IEPs. Hydrothermally grown ZNNs were fabricated on a patterned Au electrode (0.02(More)
