A futuristic, abstract background design with a gradient of deep blues and purples, symbolizing advanced technology. Incorporate subtle elements like a DNA strand or molecular structures in a glowing, translucent style. The design should include gentle light trails or orbs that flow across the background, giving a sense of energy, rejuvenation, and scientific innovation. The overall feel should be modern, sleek, and slightly ethereal, with a sense of depth and movement.
