“…Because of the dielectric materials of the photonic crystal, sensors based on BSWs are characterized by mechanical and chemical stability, thus enabling operation in aggressive environments. Consequently, BSWs have emerged as an effective alternative to SPPs [ 43 , 58 ] and have been utilized in a number of BSW based sensors [ 37 , 38 , 39 , 40 , 41 , 42 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 ], especially in biosensing [ 37 , 38 , 39 , 40 , 41 , 42 ]. Similarly to SPR based sensors, Bloch surface wave resonance (BSWR) based sensing is with a special emphasis on the measured quantity such as phase [ 46 , 47 , 48 , 49 ] or intensity [ 50 , 51 , 52 , 53 , 59 , 60 , 61 , 62 , 63 ].…”
