Abstract
Magnetic nanoparticle based disease detection system: It is a technique used to bring disease detection to the point of care diagnosis. This technique involves the use of magnetic nanoparticles that are conjugated with the detection antibodies. The blood sample to be tested will be allowed to interact with these magnetic nanoparticles. Detection of disease is dependent on the magnetic field change that happens after the blood-nanoparticle interaction. The sample without disease causing antigens will have no nanoparticles after washing, since they will not be bound to each other. The sample will contain nanoparticles that will induce a certain magnetic field, if infected with disease. The so induced magnetic field is the detection parameter. Hall sensor is used to sense this magnetic field. More the magnetic field, more the antibodies present in the blood resulting in higher intensity of disease. The work aims to display the amount of antibodies present in the sample. The system can be further developed by hybridizing fluorescence based optic sensing system and improve the reliability.
