 Obiettivo del progetto (Objective)

'The Project aims to develop novel approaches for detection and characterization of particles in the critical nanometer – micrometer size range. An improved knowledge of the make-up and origin of such particles that are present in the atmosphere and working environments is crucial for understanding their role in atmospheric pollution and human health. The role of atmospheric particles in influencing climate behavior is also poorly understood and requires more sophisticated analysis techniques. The detection of neutral isolated nanoparticles is an extremely challenging problem. The compositions and structures of particles present in the atmosphere are largely unknown owing to limited measurement capabilities. Recently it has been shown that femtosecond laser ablation is a promising technique for nanoscale depth-resolved chemical analysis while graphene nanoresonators offer much promise as ultrasensitive mass detectors. This multidisciplinary Project includes two key areas that could revolutionize particle monitoring: (1) depth-resolution analysis of micro- and nanoparticles using fs laser ablation mass spectrometry and (2) the combination of nanoelectromechanical mass sensing and fs laser ablation mass spectrometry for the detection and elemental analysis of neutral nanoparticles. A dual time-of-flight mass spectrometer will be constructed for analysis of individual aerosol particles. The potential of fs-laser ablation mass spectrometry for providing a particle depth profile will be explored and tested on well-defined core-shell micro-/nanoparticles. In addition, the elemental analysis potential of fs laser ablation mass spectrometry will be coupled with sensitive neutral particle detection, using a graphene-based mass sensor that will be developed in the host group. The outcome of the Project will be in making an important step from fundamental concepts of particle detection and characterization to laboratory proof-of-principle studies and prototype development.'

Introduzione (Teaser)

Micrometre- and nanometre-sized particles are ubiquitous in the air, affecting working conditions, pollution levels, and even weather patterns and global climate. A newly developed apparatus could make their detection and identification much easier.
