Computational Analysis of a GST‐Based Long‐Wave Infrared Microring Resonator on a ZnSe Platform as a Photonic Sensor

Advanced Photonics Research, EarlyView.
A Ge2Sb2Te5 (GST)‐based microring resonator is designed and simulated on a ZnSe‐platform that operates in the long‐wave infrared (LWIR) wavelength of 8 μm. The structure demonstrates strong power confinement and high Q‐factor. GST resonator is used for gas and biosensing applications.

DNA Biosensor for Rapid Detection of Genotoxic Compounds in Soil Samples

Sensors, 2005
An electrochemical DNA-based biosensor is proposed as a fast and easyscreening method for the detection of genotoxic compounds in soil samples. The biosensorwas assembled by immobilising double stranded Calf thymus DNA on screen-printedelectrodes.
