In the present work,a tungsten nanoneedle with a radius of~8 nm was developed by a facile and controllable method and successfully applied for monitoring incetracellular hydroxyl radicals(HO·).
Reactive oxygen species(ROS),such as hydroxyl radical(·OH),superoxide radical(O2·-) and hydrogen peroxide(H2O2) play very important roles in the TiO2 photodegradation of pollutants.
A method called solidified floating organic drop microextraction(SFODME) was developed in recent years and applied quickly for preparation of various environmental samples [1,2].
Ambient mass spectrometry(AMS) has become one of the hot research topics in recent years,because it allows rapid and direct analysis of complex samples under ambient and open-air condition with minima
