  • Publication number: 20240067805
    Abstract: The present invention provides an improved method of quantitative and/or qualitative analysis of a target molecule using nitrocellulose membrane (NCM). In particular, the present invention provides a porous nitrocellulose membrane that includes a surface and an organic nanostructured molecule that is non-covalently attached to the surface of NCM. The organic nanostructured molecule has a branched region that includes a plurality of terminal region (e.g., terminal end) moieties that are non-covalently attached or bound to a surface of the porous NCM. The organic nanostructured molecule also comprises a linear region that includes a covalently attached capture molecule that is adapted to selectively bind to a target molecule. The NCM of the invention provides an improved reproducibility, reliability, and selectivity compared an NCM in the absence of the organic nanostructured molecule.
