7. Quantum box applications?

The unique properties of quantum dots in semiconductors are already being used in biosensing, and will be used in the future to create single-photon sources for quantum cryptography (and therefore in security problems linked to information transfer), as well as lasers and amplifiers for optoelectronics, and should gradually invade the various fields of nanotechnology.

7.1 Biosensing

GFP: Green Fluorescent Protein

Fluorescent markers (also known as biosensors) currently use agents (also known as dyes, which are organic molecules such as rhodamine, GFP...) to localize a molecule within the organism, for example. However, these fluorescent agents emit light over a fairly wide frequency range, which...
