Special Issue Information

Dear Colleagues,

Currently, sensors are recognized to be essential devices as interfaces of advanced information systems. Adding suitable functions to sensors is effective way to place and enhance value on information. For instance, an RFID reader which can scan every item in a shopping basket may provide a beneficial impact to customers, and continuous in-vivo biomonitoring with flexible and biocompatible sensors drastically improves the quality-of-life of patients and promotion of health by home healthcare. Fusion of new sensing methods, device technologies and advanced materials assumes important role in such “sensing” breakthroughs. This combined special issue entitled “Bio-devices and Materials” is intended to be a reflection of timely research topics, in the area of device technologies, methods and materials to open new window of sensing technologies.

This paper presents the growth and structure of ZnO nanorods on a sub-micrometer glass pipette and their application as an intracellular selective ion sensor. Highly oriented, vertical and aligned ZnO nanorods were grown on the tip of a borosilicate glass capillary (0.7 µm in diameter) by the low temperature aqueous chemical growth (ACG) technique. The relatively large surface-to-volume ratio of ZnO nanorods makes them attractive for electrochemical sensing. Transmission electron microscopy studies show that ZnO nanorods are single crystals and grow along the crystal’s c-axis. The ZnO nanorods were functionalized with a polymeric membrane for selective intracellular measurements of Na+. The membrane-coated ZnO nanorods exhibited a Na+-dependent electrochemical potential difference versus an Ag/AgCl reference micro-electrode within a wide concentration range from 0.5 mM to 100 mM. The fabrication of functionalized ZnO nanorods paves the way to sense a wide range of biochemical species at the intracellular level. Full article

In this review, the concept, design, performance, and a functional demonstration of multifunctional complementary metal-oxide-semiconductor (CMOS) image sensors dedicated to on-chip biosensing applications are described. We developed a sensor architecture that allows flexible configuration of a sensing pixel array consisting of optical and electric sensing pixels, and designed multifunctional CMOS image sensors that can sense light intensity and electric potential or apply a voltage to an on-chip measurement target. We describe the sensors’ architecture on the basis of the type of electric measurement or imaging functionalities. Full article
