Microscopic beads are tiny spherical particles that can range in size from a few micrometers to several millimeters. They are often made from materials like polystyrene, glass, or silica and are used in various applications, including scientific research, cosmetics, and medical diagnostics. Their small size allows them to interact with biological systems and materials at a cellular level. These beads can serve multiple purposes, such as acting as carriers for drugs in pharmaceutical applications or as markers in biological assays. Their uniform size and shape make them ideal for use in laboratories and industrial processes, where precision and consistency are essential.
