A One Inch in Diameter Point-of-Care Reader Head for the Measurement of Different Bio-Analytes Concentrations

Abstract

Point of care (POC) devices facilitate access to rapid diagnostic information and play a crucial role in managing diseases. Combined with bio-sensors, POC devices are able to continuously measure the concentration of a variety of bioanalytes and mark the signs of abnormality. With the recent advancements in the state of the art electronics, miniaturized POC testing devices that have convenient wearable form factors are being materialized. A miniaturized cylindrical phosphorescent reader head with a diameter of only 25.4mm that is capable of measuring the concentration of different bio-analytes such as oxygen and glucose is reported in this paper.
