Microbial alphabet rendering on white background — transparent background

A high-detail 3D render displaying the entire alphabet from a to z, where each letter is formed by a clear, glass-like capsule containing dense, dark clusters of microscopic bacteria. Each character has a unique, organic shape defined by the structural constraints of the letter itself, filled with intricate, tangled rod-shaped and spherical biological specimens. The lighting is bright and even, casting subtle shadows to give the letters depth and volume against the sterile white background. The aesthetic is scientific and clinical, resembling micro-photography or a high-end medical visualization. The rendering emphasizes the contrast between the smooth, transparent glass casing and the complex, textured, dark interior contents, creating a cohesive visual set of conceptual typography.
