Abstract: A novel apparatus and method is described for detection of very small quantities (a few hundred molecules) of bioparticles in nanoliter/picoliter quantities of a sample. The apparatus involves a very small and low cost apparatus that contains a fluorometer. The detection process uses the fluorescence of nanoparticles. Dielectrophoresis is used to concentrate, mix and position the target particles with regard to the light sensor such that maximum detection efficiency is achieved. This allows low cost implementation of low cost point of care tests for disease (animal and plant), infection, food-borne bacteria detection, nucleotide sequencing and pathogen detection (bioterrorism) in real world applications.
Abstract: A composition and method of detecting antigens and killing bacteria and virus is described. The composition and method comprise a fluorescent nanoparticle conjugated to a substance capable of binding specifically to a antigen and exposing the location containing the fluorescent nanoparticle and antigen to a wavelength of light capable of exciting the fluorescent nanoparticle.
