The immunochromatographic strip developed by YAN Xiyun and colleages is based on the use of magnetic Fe3O4 nanoparticles which, loaded with appropriate antibodies, could detect the glycoprotein of Ebola virus (EBOV) at 1 ng/mL concentrations which is 100-fold more sensitive than the standard strip method. This sensitivity is comparable with ELISA, but much faster (within 30 min) and simpler.
