Whispering gallery mode resonators (WGMR) are an efficient tool for the realisation of optical biosensors. A high Q factor preservation is a crucial requirement for the good biosensor performances. In this work we present Eudragit®L100 coated microspherical WGMR as an efficient immunosensor. The developed protocol was morphologically characterized using fluorescence microscopy. The functionalization process was tuned to preserve the high Q factor of resonator. The protein binding assay was optically characterized in terms of specificity in buffer solution

Abstract
Whispering gallery mode resonators (WGMR) are an efficient tool for the realisation of optical biosensors. A high Q factor preservation is a crucial requirement for the good biosensor performances. In this work we present Eudragit®L100 coated microspherical WGMR as an efficient immunosensor. The developed protocol was morphologically characterized using fluorescence microscopy. The functionalization process was tuned to preserve the high Q factor of resonator. The protein binding assay was optically characterized in terms of specificity in buffer solutionFile in questo prodotto:
