空气中的单线态氧（1O2）分子，这是在TiO2光催化反应过程中产生的，并从表面扩散到空气中，检测到在相反的表面使用三苯撑二亚胺（TDI）分子在单分子水平。这种新颖的1O2纳米传感器在70 × 70平方微米的面积内可检测到约1000个1O2分子，可以很容易地检测到距离环境空气中1000微米以上的单个1O2分子。
Airborne singlet oxygen (1O2) molecules, which are generated during the TiO2photocatalytic reactions and diffused from the surface into air, were detected at the opposite surface using terrylenediimide (TDI) molecules at the single-molecule level. The novel1O2nanosensor, which has a detectable number of about 10001O2molecules in 70 × 70 square micrometers, can easily detect the single1O2molecule at a distance of over 1000 micrometers from the place of its creation in ambient air.
