The Agnes group is continuing to develop the analytical aspects of a novel picoliter sample handling strategy that they introduced as 'Wall-less Sample Preparation' (WaSP). In addition to this aspect of the Agnes group's program of research, there is a strong commitment to apply the WaSP technology to the chemistry of trace components in levitated picoliter droplets/particles.

Example applications include heterogeneous and homogeneous reactions on suspended particles that are of relevance to the troposphere, metal-organic chemistry within the environment of a levitated droplet/particle, and investigation of biological compounds at sub-nanomolar concentrations in physiological fluids of relevance to human health and disease.
