Detection of Magnetic Field Concentrated Analytes in a
Lateral Flow Capil ary
Kent J. Voorhees, Roy R. Mondesire, and Christopher R. Cox
Summary: A lateral flow capillary devise to detect target analytes that are concentrated by a
magnetic field
Description: This invention is of a method to detect targeted analytes. The method most often
used now is Lateral Flow Chromatography (LFC), which has many drawbacks including, the need
for extensive optimization, sensitivity, specificity, lack of quantitative data, and extensive
component selection. This method uses Surface Enhanced Raman Spectroscopy (SERS) and
antibodies specific to the targeted analyte. These antibodies are easily attached to beads (one
specific for SERS and one for a nano-magnet). The method reports both quantitative and
qualitative results in a rapid fashion.
Main Advantages of this Invention
 Ability to receive quantitative and qualitative
information quickly
 No need for the nitrocellulose membrane
required for LFC
 More specific and sensitive than LFC
 Simpler than LFC
Potential Areas of Application
 Virus and bacteria detection
 Medical testing
 Agriculture
 Home pregnancy tests
