Compounds with magnetic properties are provided herein, which belong to the category of metal oxide nanoparticles, coated and conveniently functionalized, which are conjugated with naphthalene compounds related to agglomerates and β-amyloid plaques present in neurodegenerative diseases. These new nanoparticles (NPs) are used for the non-invasive detection of agglomerates and amyloid plaques using the Magnetic Resonance Imaging (MRI) technique. The nanoparticles described here cross the blood-brain barrier (BBB), without the use of any membrane-disrupting agent. Likewise, they bind with high affinity and specificity to the agglomerates and β-amyloid plaques, and are used as contrast agents in MRI for the early detection of Alzheimer's disease (AD).
