In this study. a label-free sensing method based on a functionalized nanopipette is proposed for detection of alkaline phosphatase (ALP) activity. This method is based on the unique charge transport properties of nanopores in which the ionic current can be modulated by variation in the charge on the inner surface of the nanopipette. A phosphorylated peptide. https://foldlyers.shop/product-category/bench-oven/
