Abstract: Embodiments are directed to diagnostic devices based on surface-enhanced Raman scattering comprising: an inlet module receiving liquid to be analyzed; a reaction module having a first region arranged with a receiving hole and a second region arranged with an output hole, wherein the receiving hole is communicated with the output hole through a flow channel configured with at least one chemical set, the reaction module receives the liquid delivered by the inlet module via the receiving hole, and the liquid to be analyzed flows through the chemical sets placed in the flow channel to obtain nanoparticles-carrying liquid, and the nanoparticles-carrying liquid configured to flow into the second region of the reaction module; and a detection module receiving the nanoparticle-carrying liquid from the output hole of the reaction module.

Abstract: Present disclosure relates to a method of diagnosing malaria infection in a patient by Surface Enhanced Raman Spectroscopy (SERS). The method includes obtaining a sample from said patient, mixing the sample with a suspension of magnetic nanoparticles, wherein said magnetic nanoparticles adsorb hemozoin present in the sample onto their surface, obtaining the SERS spectra of the sample, and correlating the obtained SERS spectra to the presence or amount of hemozoin in the sample, wherein the presence of hemozoin is indicative of malaria infection.
