Bio nano sensors part 20🥴The process of manufacturing graphene oxide nanofilms and their use as bio-nanosensors in an airborne setting involves several steps. Here's a detailed breakdown: ### Manufacturing Graphene Oxide Nanofilms 1. **Graphene Oxide Synthesis**: - **Hummers Method**: This is one of the most common methods for synthesizing graphene oxide. It involves the oxidation of graphite using strong oxidizing agents such as potassium permanganate (KMnO₄) and sulfuric acid (H₂SO₄). The pro
