Raman spectroscopy is established as a valuable tool to study and characterize two-dimensional (2D) systems, but it exhibits two drawbacks: a relatively weak signal response and a limited spatial resolution....
heterostructures [13, 14], and the introduction of defects to modify its physical properties. In the latter case, materials with the ability to host single photon emitter defects have attracted much attention [15-18] due to the importance of single photon emitters for the development of quantum information technologies. A promising candidate arising from this context is hexagonal boron nitride (h-BN) [19-22], a wide bandgap 2D material with several interesting properties [23-26], best known for its use as a dielectric substrate for graphene and
We have found different Raman signatures of AB fibrils and in brain tissues from unmixed analysis, providing a detailed image of amyloid plaques in the brain, with the potential to be used as biomarkers.
The deposition of amyloid plaques is considered one of the main microscopic features of Alzheimer’s disease (AD). Since plaque formation can precede extensive neurodegeneration and the main clinical manifestations of...
Given the long subclinical stage of Alzheimer's disease (AD), the study of biomarkers is relevant both for early diagnosis and the fundamental understanding of the pathophysiology of AD. Biomarkers provided...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
