A pure light gray gradien

A pure light gray gradient background gradually deepens from the center of the image outward. At the center of the image is a transparent spherical microcapsule with extremely high transparency and a subtle glossy surface. Inside,there are two smooth and delicate black molecular-like spheres that approach each other yet remain separate. Surrounding the microcapsule are multiple layers of glossy transparent bubbles/cell layers arranged in a wavy skin structure. The edges have a faint halo,and the surface has fine texture simulating cell-like patterns. Soft cool-toned light shines from one side,outlining the contours of each element and creating changes in light and shadow and light beams. Fine water ripple textures cover the entire image,enhancing the sense of "deep penetration.",Translucent,
