Title:
APPARATUS AND METHOD FOR BIOLOGICAL ANALYTE STUDYING USING X-RAY FLUORESCENCE
Document Type and Number:
WIPO Patent Application WO/2022/109866
Kind Code:
A1
Abstract:
An apparatus comprises: an X-ray source (101); an X-ray detector (100); the X-ray source (101) is configured to direct an X-ray beam (102) toward a surface (104) at a glancing angle (108) at which the X-ray beam (102) undergoes total external reflection by the surface (104); a first biological analyte (910) is immobilized to the surface (104) and a first element (911) is attached to the first biological analyte (910); the X-ray beam (102) is capable of causing emission of characteristic X-rays (109) of the first element (911); the X-ray detector (100) is configured to receive the characteristic X-rays (109) of the first element (911) but not the X-ray beam (102) reflected by the surface (104).
