This study was carried out to investigate the effect of hybrid plasmonic material thicknesses, which are Ag/TiN and Ag/ZrN on the sensitivity of SPR sensor in detecting glucose and sucrose. A Krestchmann configuration of surface plasmon resonance (SPR) sensor had been theoretically developed via prism coupling technique. A 633nm of red laser was incident onto the prism’s hypothenuse side to excite the SPR. The effect of Ag/TiN and Ag/ZrN thicknesses ranging from 35nm to 60nm on the sensitivity of SPR sensor was studied. The deployment of Ag/ZrN at 44nm/10nm thicknesses resulted the resonance angle shifting about 0.91º from 44.67º to 45.58º as it was exposed to the glucose and sucrose. In contrary, the Ag/TiN coated sensor indicated large angle shifting only for glucose detection which portrays its non-versatility feature. The proposed Ag/ZrN based SPR sensor able to identify the analytes, with almost similar refractive index values with sensitivity values of 0.6725 °/RIU (glucose detection) and 0.6724°/RIU (sucrose detection). In conclusion, Ag/ZrN (tAg=44nm, tZrN=10nm) offers better sensitivity and selectivity performance than Ag/TiN because of the absorption enhancement inside the Ag due to the high scattering efficiency of ZrN.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
