Submikrometerbereich

Submikrometerbereich refers to the scale of size that is smaller than one micrometer (1 µm) but typically larger than one nanometer (1 nm). This range encompasses dimensions from approximately 100 nanometers to 1000 nanometers. Objects within the submikrometerbereich are beyond the resolution of the naked human eye and standard light microscopes, requiring specialized optical or electron microscopy techniques for visualization and study.

This size range is significant in various scientific disciplines. In biology, it is where many cellular structures and organelles reside, such as mitochondria, lysosomes, and ribosomes. Viruses also fall within the submikrometerbereich, explaining why they cannot be seen with conventional light microscopy. In materials science, the properties of materials can drastically change when their features are in the submikrometerbereich, leading to phenomena like quantum confinement effects or altered optical and mechanical characteristics. Nanoparticles and some fine powders also belong to this size classification.

The study and manipulation of objects in the submikrometerbereich are crucial for advancements in fields like nanotechnology, medicine, and advanced manufacturing. Techniques such as scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are essential tools for imaging and analyzing structures at this scale.
