An improved flat dc-thin film SQUID with Dayem bridges has been used for the measurement of the magnetic fields of human heart and skeletal muscles. Using an antenna in form of superconducting asymmetric second derivative gradiometer a sensitivity to magnetic fields of I x 10 -12 T Hz-1/2 could be r

## Abstract We have developed concentric multiloop DCβSQUID gradiometers for nondestructive evaluation, which were integrated on a 3 Γ 3 mm^2^ Si chip using Nb thinβfilm fabrication technology. In order to obtain high spatial resolution and to cancel magnetic noise, a coplanar concentric secondβord
A two-channel fluorometric sensor system for the detection of the waterbloom phytoplankton Microcystis aeruginosa has been developed. Excitation wavelengths of 620 and 440 nm were used, the former for detecting the cyanobacteria themselves, and the latter for subtracting the interference due to euka
Enzymes were (co)hnmobilized on the pH-sensitive gates of an eightchannel field-effect transistor @ET). Glucose was analysed with a glucose dehydrogenase (GDH) FET, maltose with a coimmobilized maltase (MAL)/GDH FET, sucrose with a cohnmobilized invertase (INV)/GDH FET, lactose with a /3-galactosid
