Prompt: A close-up scientific cross-section view of a spherical lipid nanoparticle approximately 80 to 120 nanometres in diameter, showing its layered fatty-acid shell encapsulating coiled mRNA strands inside. The outer surface features short polyethylene glycol chains projecting outward, and the inner cavity contains a dense tangle of genetic material. The cutaway reveals the concentric lipid bilayer structure with distinct inner and outer membrane regions. Style: Detailed digital illustration blending technical schematic linework with painterly atmospheric rendering, as if a scientific textbook were reimagined by a noir graphic novelist. Colour palette of deep midnight blue, charcoal black, and slate grey as foundations, accented with electric teal, bioluminescent green, and cold amber. Lighting is dramatic and directional, suggesting surveillance or laboratory environments — pools of cold light against deep shadow, with occasional glowing circuit-trace highlights. Compositions favour tight framing with layered depth: foreground technical detail dissolving into abstracted background geometry. Detail level is high but purposeful, prioritising legible structure over decorative complexity. Mood is clinical yet ominous, precise yet unsettling. No text, lettering, captions, logos, watermarks or borders unless it is a technical drawing.
