DEVICES AND METHODS FOR DETECTING HAEMATIN, HAEMOZOIN AND RELATED IRON CONTAINING COMPOUNDS

摘要

In practical applications, change magnetic state, hemoglobin has been utilized suitable characteristic by malaria infection, depends on the magnetic field applied by detection malarial pigment. Fig. 1 shows the device shown at (10), detects photoacoustic technique using magneto-optic for executing. Equipment (10) includes light source (12), it generates optical radiation beam (14), second slips over across polarizer (16), variable L C retarder (0 or 180 °) (18) retardance, (chopper 20) holds in specimen holder (24) hitting sample (22). Sample be directly with acoustic detector (26). Device (10) further includes the field strength that electromagnet (28) and Gauss meter (30) can be used to measure magnetic field. Related advantage, this method be make in in-vivo measurement a possibility that, and avoid the problem that optical scattering and traditional optical measurement to turbid liquid such as whole blood.
