| Popis: | Nanolayer deposition(s) of Ag and AgC composite on a plastic substrate was used to design disposable stochastic sensors. Three shapes of nanocoatings were tested. The first shape was obtained by deposition of a nanofilm of Ag on the plastic material the second shape was obtained by deposition of a composite AgC nanolayer on the plastic material the third shape was obtained by nanolayer deposition of a composite material of AgC on the top of the Ag nanofilm deposited on the plastic material. &alpha Cyclodextrin was used to modify the active surface of the sensor. Wide linear concentration ranges were obtained as follows: for de-assay of &alpha amylase in whole blood: 1.00 × 10&minus 7&ndash 1.00 × 103 U mL&minus 1 and for the assay of &alpha amylase in saliva: 1.5 × 15&ndash 1.5 × 102 U mL&minus 1. &alpha Amylase was reliably determined from whole blood and saliva samples using the proposed disposable stochastic sensors. |
