Materials researchers at the National Institute of Standards and Technology have developed a simplified, low-cost process for producing high-quality, water-soluble “quantum dots” for biological research. By using a laboratory microwave reactor to promote the synthesis of the widely used nanomaterials, the recently published NIST process avoids a problematic step in the conventional approach to making quantum dots, resulting in brighter, more stable dots.
