Scanning electron microscope image of a human hair (black and white). • SIZE: Scale bar representes 50 µm • IMAGING TOOL: Table-top Scanning Electron Microscope (SEM)

Red blood cells carry a protein called hemoglobin which has a molecular structure adapted to transport oxygen to body tissues. The cells' flexibility allows them to flow through tiny capillaries. • SIZE: The typical diameter of a human red blood...

This scanning electron microscope image shows the relative thickness of typical nanowire in comparison with a strand of human hair. • SIZE: The hair is about 100 µm in diameter; the nanowire's diameter is about 100 nm. • IMAGING TOOL:...

This is a scanning electron microscope image of a single strand of human hair. • SIZE: The diameter of a human hair ranges from about 50 µm to 100 µm. • IMAGING TOOL: Scanning electron microscope

This is an optical microscope image of a human venule—a tiny blood vessel. A venule is tiny blood vessel that connects capillaries—where the blood exchanges the oxygen it carries for carbon dioxide—to larger veins leading back to the heart. •...

This scanning electron microscope image shows a hydrogel scaffold grown for studying brain tissue engineering and nerve regeneration. Hydrogels are polymers of great interest to researchers studying tissue engineering and nerve regeneration because they are compatible with a range of...

Red blood cells carry a protein called hemoglobin which has a molecular structure adapted to transport oxygen to body tissues. This scanning electron micrograph shows the cells' characteristic donut-like shapes. • SIZE: The typical diameter of a human red blood...
