Summary

Story summary

A process yields quantum-grade nanodiamonds in a single step.
It uses a diamond press with sodium chloride to yield nanodiamonds with spin lifetimes in four minutes.
Production time drops to one week instead of decades.
Biological tests show no toxicity in human cancer lines and enable dual-color imaging with nitrogen vacancy (NV) and H3 centers; temperature control could boost brightness.

History

Historical Context

In 1955, General Electric achieved a breakthrough in synthetic diamond production using high-pressure techniques, marking a significant advancement from earlier attempts dating back to the 19th century. This innovation has evolved, with modern methods now producing nanodiamonds in just one week. The growing market for synthetic diamonds, which constituted 17% of the diamond jewelry market by 2023, highlights their expanding applications in various fields.
