About the DNA Double Helix black filled icon
This icon shows a classic DNA double helix with two twisting strands connected by horizontal rungs, forming the familiar ladder-like structure. It represents genetics, heredity, molecular biology and biotechnology. Use it in science education materials, healthcare apps, research websites, lab reports and genetic-testing product pages.
The strands curve smoothly into an hourglass twist with evenly spaced connecting rungs, giving a clean and recognizable silhouette. It pairs well with microscope and lab-flask icons in science sets. Keep it at a reasonable size so the individual rungs remain distinguishable.
This is the solid black filled version of the dna double helix icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
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.
