“…Currently, several works have been done using ZnO/Au SPR biosensor for detection of biomolecules using prism coupling method. Various biomolecules have been immobilized on ZnO surface for SPR detection involving glucose [42], DNA [73], antibody [74], and cholesterol [61].…”

“…There are various glucose sensors available in the market for glucose measurement based on electrochemical or optical techniques such as electrochemical signal transduction (EST) [105] and fluorescence signal transmission (FST) [106,107]. SPR detection of glucose can be made using glucose oxidase enzyme based on the catalytic reaction of glucose oxidase on glucose, and hence it is very specific and sensitive to the glucose [42]. Glucose oxidase enzyme having IEP ∼4.22 are immobilized on the ZnO layer having IEP 9.5 through physical absorption method.…”

“…Traditionally SPR was measured in the prism coupling Kretschmann configuration [5][6][7][8] in which a high index prism coated with a thin metal layer on its base is immersed in the dielectric to be sensed as shown in Fig. 1(a).…”

“…Технологии ППР непрерывно развивают-ся. Возрастает потребность в ППР биосенсорах для выявления опасных токсинов и обнару-жения патогенных микроорганизмов в регионах, не имеющих доступа к лабораторному обо-рудованию.Наиболее распространены сенсоры, основанные на геометрии Кречманна [5][6][7][8]. Обыч-но в этих устройствах используется метод дискретного измерения оптического сигнала при изменении угла падения излучения на образец, измерения весьма трудоемки, а сами устрой-ства громоздки.…”
