Tunable infrared metamaterial-based biosensor for detection of hemoglobin and urine using phase change material

Abstract This paper reports about the outcomes from an investigation carried out on tunable biosensor for detection using infrared in the range of 1.5 µm and 1.65 µm. The biosensor is made of phase change material formed by different alloy combinations, Ge2Sb2Te5 (GST). The nature of GST allows for...
