For the first time, the number of #graphene patents exceeded #nanotubes in 2021! Carbon nanotubes always had the highest number of patents among different #nanomaterials in previous years. The third place belongs to #quantum_dots.
Carbon #quantum_dots functionalized with boronic acid ligands can interfere with the function of #coronavirus S protein and significantly inhibit its entry into the host cells.
Various manufacturers have commercially been producing #cadmium free #quantum_dots products because cadmium quantum dots may be banned in the near future in many countries.
