In several application fields, plasmonic sensor platforms combined with bio-receptors are intensively used to obtain biosensors. Most of these commercial devices based on a disposable chip. Usually gold chip, functionalized specific bio-receptor, inside costly system, is used. this work, we propose low-cost and small-size for monitoring an innovative optical waveguide made bacterial cellulose (BC). particular, have sputtered the green slab that able excite localized surface plasmon resonance (LSPR). Experimental results presented capabilities using BC-based composite as eco-friendly platform, which could be exploited realizing The has been fibers simple equipment. More specifically, connect LSPR light source spectrometer. novel sensing approach tested two different configurations BC, without ions BC.
