NEFL and amyotrophic lateral sclerosis: The same sensing strategy could be extended to amyotrophiclateral sclerosis (ALS) diagnostics, targeting CSF biomarkers suchas phosphorylated and light-chain neurofilaments (pNfH, NfL), superoxidedismutase 1 (SOD1), and TAR DNA-binding protein 43 (TDP-43), whichexist at subpicogram concentrations.
