MB and heart disorder: Liquid phase exfoliated BPNSs can possess a negative zeta potential,195 which renders it possible to noncovalently functionalize BPNSs with positively charged species (e.g., small molecules, polymers) through electrostatic interactions.195, 196, 201, 202, 203, 204 For instance, Sabherwal and co‐workers employed nanostructured BP as a platform in an electrochemical sensor for the detection of Myoglobin (Mb), a cardiac disease biomarker.
