Abstract

In this work, we report a new approach for fabricating a high sensitivity lysozyme biosensing. The aforementioned device consists of an optimized Fabry-Perot micro-cavity (FPC) fabricated onto cleaved end of a standard single mode fibre (SMF). The sensitive part of our device is the external face of the FPC, which was ad-hoc functionalized in order to provide high selectivity and high sensitivity. From the experimental test carried out, we have found that our sensor has a sensitivity higher than others reported so far, to the best of our knowledge. In addition, the platform introduced here can operate over a broad wavelength which makes it adaptable to different sensing targets. In addition, our sensor offers several advantages such as repeatability of fabrication, wide operating range and small size and weight, which benefit its sensing applications.
