Abstract: One MoNomer Ion Imprinted Polymer (OMNiIIP) development is an attractive concept which typically uses a crosslinking monomer that can act both as a functional monomer and crosslinker, simultaneously. This technique is meant for enhancing binding and selective characteristics of polymer vis-a-vis traditionally formulated ethylene glycol methacrylate and functional monomer based imprinted polymers. The present work is aimed to evaluate Cu (II) ions using OMNiIIP developed from an acryloylated acidified biomass of blue green algae, Aulosira sp., which is efficient to mitigate non-specific adsorptions, especially biosorptive metal ions accumulation. The alga-OMNiIIP modified pencil graphite electrode was used for differential pulse anodic voltammetric analysis of copper (II) with detection limit upto 0.0018 ng mL-1 (3дт). Algal stains in monomeric unit of OMNiIIP chain in this work have not only inculcated its electroconducting activity, but also facilitated metal ion imprinting, exploiting their ligating carboxylate groups present in higher ratio
