Scientists brew “quantum ink” to power next-gen night vision

Infrared camera manufacturers face increasing bans on toxic heavy metals like mercury and lead in detectors due to environmental regulations, creating bottlenecks just as demand surges for autonomous vehicles and medical imaging. NYU researchers developed "quantum ink" made from environmentally friendly quantum dots that can be manufactured like brewing ink and coating surfaces, dramatically reducing costs compared to traditional atom-by-atom assembly methods while achieving microsecond response times.
