A new type of surface acoustic wave sensor system for assaying the activity of pancreatic lipase has been proposed. The assay of this enzyme is based on the change in conductance of the solution caused by the release of a fatty acid, using triolein as a substrate. A linear relationship between frequ

Nitrobenzene and water adsorption isotherms were obtained on an aminopropyltriethoxysilane coated surface acoustic wave sensor (SAWS) at < 5, 17, 33 and 47% relative humidity (RH) at 6, 13, 2.5 and 47ยฐC. The nitrobenzene isotherms were BDDT type 1 (Langmuir) and water isotherms BDDT type 3. The nitr
A bulk acoustic wave (BAW) impedance sensor has been applied for in situ monitoring of the whole process of DNA oxidative damage induced by the vitamin C (Vc)-Fe (III) system, based on its real-time responses to the density-viscosity change of the tested solution due to the damages occurring on the
A surface acoustic wave (SAW) sensor system utilizing a SAW resonator operating at 61 MHZ and a pair of parallel electrodes in series was applied to the detection of organic mixtures. Linear frequency shifts were observed as the water content of organic solvents changed. The detection limit was 2 mg
Isotherms for water, nitrobenzene and 2-nitrotoluene adsorbed onto a platinum/lead coated 15 MHz AT-cut piezoelectric crystal are reported. Both the nitrobenzene and 2-nitrotoluene isotherms were BDDT type 1 (Langmuir) in shape, as were the water isotherms, and showed predictable behaviour over temp
