About the Molecule black outline icon
This icon shows a symmetric polycyclic skeletal structure with small circles marking oxygen atoms attached by double bonds around the fused hexagonal rings. It represents chemistry, biochemistry and molecular science, suiting chemistry apps, pharmaceutical websites, lab dashboards, science presentations and education materials.
The repeating ring pattern and evenly spaced oxygen markers create a balanced, technical composition typical of skeletal chemical formulas. It pairs well with atom, DNA or flask icons in a science set, and works best at medium-to-large sizes where the ring detail stays legible.
This is the black outline version of the molecule icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
