👉 A microchemist is a person who specializes in preparing, packaging, and selling ultrafine particles (ultramicros) as an ingredient for pharmaceutical and medical products. These ultrafine particles are typically smaller than 100 nanometers, which makes them very small and difficult to process and store. In the context of medicine, ultramicrochemists work with these particles to improve drug delivery and enhance therapeutic efficacy. They use advanced techniques such as microfluidics, quantum dots, and
