Molecule black outline icon

About the Molecule black outline icon

A larger central sphere connects by straight bond lines to six smaller spheres arranged around it, each circle carrying a small inner curve that suggests a highlight. The radial cluster reads as a molecular structure or a connected network, fitting chemistry and biology course materials, pharmaceutical and lab websites, research and R&D slide decks, skincare ingredient callouts, and science app navigation.

Bonds radiate at even angles so the shape stays balanced in a square frame, and the center node is drawn slightly larger to mark the core atom. It works alongside atom, flask, DNA and microscope icons in the science set. At sizes under 24 px the inner highlight curves can close up, so prefer 32 px and above.

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.

Download it free as a scalable SVG vector or transparent-background PNG in seven sizes (16 to 512px), copy the SVG code straight into your project, or open it in the free online editor to change colors, apply gold, silver, neon and gradient styles, animate it, or convert it to EPS, PDF and DXF.
