About the Molecule black outline icon
A large circle sits slightly off center with four straight bond lines radiating to smaller circles placed above, left, right and lower right, each drawn at a different diameter. The structure communicates molecular bonding, compounds and scientific research, which makes it useful for chemistry and biotech websites, lab and pharmaceutical dashboards, skincare ingredient callouts, science education material and R&D presentations.
The uneven node sizes and irregular bond angles keep the arrangement organic rather than symmetrical, and every line meets its circle edge cleanly so the joints stay sharp. It pairs with atom, DNA, flask and microscope icons in the same set. At 24 px the smallest node can fill in, so prefer 32 px upward.
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.
