A stimuli-responsive polymer modified nanopore for measuring β-amyloid peptide and zinc ions in brains of live mice with Alzheimer's disease

A copolymer-modified glass nanopore combined with microdialysis was used for assaying cerebral Aβ monomer and Zn2+. In the presence of Aβ monomer, the copolymer stretched. Then, the Zn2+ altered surface charges and fluorescence.
