Magnetosomes

Magnetosomes are tiny structures found inside certain bacteria that contain magnetic mineral crystals, such as magnetite. These structures act like natural compasses, helping the bacteria sense Earth's magnetic field. This allows them to navigate through their environment, often guiding them toward optimal conditions like nutrient-rich areas or away from harmful substances. Magnetosomes are arranged in chains within the bacteria, enabling efficient magnetic sensing. The study of these structures offers insights into both microbiology and potential biomedical applications, such as targeted drug delivery or imaging techniques.
