Device integration of the CoBiSS spectrometer and modelisation of (L)SPR chip for the detection through CoBiSS

Abstract : As the world is moving towards Internet of Things, an optical detection device is presented that can be utilized in this domain. This device can be used to do tests that use optical detection for analysis like monitoring of Health of a person by doing a blood test or other medical analysis and also be used to monitor environment by testing water or air in cities, mountains, factories, rivers and so on for a practical purpose. To create this optical detection device, a combination of spectrometer named Coupled Bi-Directional Sampling Spectrometer (CoBiSS) [Patent number WO2009127794A1] and Surface Plasmon Resonance (SPR) Chip has been used. For the optical integration, a new analysis of the sampling in the spectrometer CoBiSS is presented. Followed by, Device and Optical Integration of CoBiSS has been done to remove all the moving parts. It was necessary to make the device small that can be handheld and portable. For ease of use a Graphical User interface was developed. For detection, CoBiSS was added with a chip of SPR. A modelisation of SPR chip was done to maximize its sensitivity. A new Localized Surface Plasmon Resonance (LSPR) chip has been proposed to work with CoBiSS. Optimization of LSPR chip has been performed to maximize the sensitivity. A new definition for the calculation of Sensitivity has been proposed. This device needs the addition of functionalization on (L)SPR Chip for detection and a final application. This device could be an ideal “Thing” in Internet of Things
