Bacteriophages are viruses that infect bacteria, multiplicate in them and burst out of them killing the bacteria. Bacteriophages are a possible therapy against multi-drug-resistant bacteria. The structure of the bacteriophages looks odd, but they really look like this.
Antibodies (Y-shaped) responding to an infection with the new coronavirus SARS-CoV-2 (orange). Antibodies bind to specific antigens, for instance viral proteins, marking them for destruction by other immune cells, such as the macrophage white blood cell behind the virus.
I used an antibody structure and a spike protein structure from the RCSB Protein Data Bank ( www.rcsb.org.).PDB sources: 1igt, 6vsb.
Modeling mainly in ZBrush, shading, composition and rendering in Blender 2.82.
