Sensing of nanoscale objects with ultrahigh sensitivity is highly desirable for applications in various fields, such as in early-stage diagnosis of diseases, process control in semiconductor manufacturing, environmental monitoring, and homeland security. For instance, the high concentrations of nanoparticles emitted by vehicles and industrial processes contribute significantly to increasing rates of respiratory and cardiac diseases, because nanoscale particles can penetrate the lungs to cause inflammation and even spread to other organs inside the human body.

Over the past few years, the high-Q optical microcavity has shown great potential in ultrasensitive detection because of the strongly enhanced light-matter interaction therein. The microcavity sensing community has been expanding rapidly, with over 100 research groups in the world. The sensing targets range from dispersive to dissipative nanoparticles, including proteins, DNA, nucleic acid and viruses. Significantly, the detection limit of the microcavity sensing has been pushed down to single nanoparticle (molecule) level. This symposium will focus on the nanoparticle detection. It will highlight important recent developments in the field, and aims both to provide a focussed forum to discuss ongoing research and challenges, and to stimulate new interest.
