Abstract
Combining nanotechnology with optical trapping offers many possibilities for developing directed nanoscale probes that can target and report on specific types of physical, biological, and chemical interactions. Bright fluorescent nanodiamonds containing many nitrogen-vacancy lattice defects are among the most promising candidates for such applications, as they possess both desirable trapping properties and optoelectronic properties that are amenable to a range of different sensing modalities. In this presentation, I’ll discuss our progress in understanding the most effective ways of combining optical tweezers with spin-sensitive optical detection schemes in order to unlock the full potential of nanodiamond-based sensing. I will also discuss how modes of optical manipulation and nanostructure shape can be used to provide additional capabilities for vector magnetometry.
