如果高价耳温计不能足够准确地告诉你,宝宝是否发烧了,那就试试你的订婚戒指吧。研究者已能用直径100纳米的钻石探知注入纳米金粒子的细胞内0.044℃的微小温度变化。当原子离开钻石晶格产生所谓氮晶格空位中心,被绿光照射时,它们将基于温度变化发出不同强度的红光。通过监控光的强度就可作为一个超级准确的原子尺度温度计。科学家利用纳米硅传感器将纳米金粒子和钻石晶体(想象图中 If a high-priced ear thermometer can not tell you exactly enough if your baby has a fever, try your engagement ring. Researchers have been able to use diamonds of 100 nanometers in diameter to detect tiny temperature changes of 0.044 ° C in gold nanoparticles infused into cells. When an atom leaves the diamond lattice to create a so-called nitrogen lattice vacancy center and is illuminated by green light, they emit red light of varying intensities based on temperature changes. By monitoring the intensity of light can be used as a super-accurate atomic scale thermometer. Scientists use nanosilica sensors to deposit gold nanoparticles and diamond crystals (pictured here)
