病毒颗粒衣壳结构图

一幅引人注目的包膜二十面体病毒颗粒 3/4 视角剖面科学插图。深海蓝外脂质包膜上镶嵌红色蘑菇形糖蛋白刺突，右侧四分之一剥开，露出下方金色线框二十面体衣壳。衣壳内部为珊瑚粉色单链 RNA 盘绕。右下角白色无衬线标注 「100 nm」 比例尺。背景为深蓝渐变，粒子后有微弱放射光晕。细线箭头标注：刺突蛋白、脂质双层、衣壳、ssRNA。整体风格接近 Science 期刊封面，写实材质，左上方戏剧性布光。

A striking scientific illustration of an enveloped icosahedral virus particle, shown in a 3/4 perspective cutaway. The outer lipid envelope (semi-transparent dark-navy surface with embedded glycoprotein spike proteins rendered as red mushroom-shaped trimers) is peeled back on the right quarter to reveal the icosahedral capsid beneath (wireframe hexagonal tiling in gold). Inside the capsid, a loose tangle of single-stranded RNA is depicted as a soft coral-pink coiled strand. Scale bar at bottom-right: "100 nm" in white sans-serif. Background: deep space-blue gradient with a subtle radial glow behind the particle. Labels with thin leader lines: "Glycoprotein spike", "Lipid bilayer", "Capsid", "ssRNA genome". Style: Science magazine cover-quality, photorealistic surface materials, dramatic studio lighting from upper-left.
