Subject: light beige solid background, wavy biological tissue microscopic base layer, fine grid texture surface layer, three virus-like suspended particles. Scene: biomedical microscopic immune mechanism popularization 3D visual design. Style: microscopic realistic research style, 3D solid modeling, dynamic particle decomposition effect. Color palette: light and elegant base layer, soft light color of light texture on tissue surface, virus particles differentiated into gray and green for shape distinction, particles unified with the same system green tone. Lighting: global soft diffused lighting, no strong light-dark contrast; fine texture lighting on particle surfaces, decomposed and ejected particles with slight translucent soft light. Composition: wavy curved surface of biological tissue spreads in the center, three virus particles are scattered and suspended above the surface; left gray particle decomposes and diffuses, middle green particle is fully raised, right green particle ejects micro-particles upward, balanced layout with clear dynamic narration, no text in the画面. Purpose: immune mechanism popularization illustration, antiviral product promotion visual, biomedical report illustration, medical research courseware and academic poster base image.
