孤獨(dú)無助

Biosensors based on DNA intercalation using light polarizationens. The experimental technique is based on monitoring the decrease of polarization, caused by the displacement of an intercalated fluorescent dye molecule by the analyte molecule (carcinogen). The magnitude of the polarization decrease is proportional to the concentration of the analyte.

ISFET affinity sensors in which modified ion-sensitive field-effect transistors (ISFETs) are used. The ion-step method is based on a dynamic measuring principle, whereas many other potentiometric methods are static and measure in a state of thermo-dynamic equilibrium. A number of authors report on measuring protein adso

Liposome-Based immunomigration assaystems span a range of analyte detection for agricultural (.), environmental (.), and clinical interests (.–.). Furthermore, similar bilayer membrane-based reagents made of red blood cell ghosts have been used for the detection of drugs of abuse in a commercially available assay (.).
