Optical trapping and levitation offers a non-contact, non-destructive tool for manipulating and controlling particles, with light. The range of particle sizes one can manipulate spans almost six orders of magnitudes, but they are traditionally classified two different regimes of optical trapping, the first relying on the confinement of small particles; and the second related to the confinement and cooling of atoms or collection of atoms. In this talk, I will discuss our procedure to combine these two trapping schemes into the one trapping system using embedded defects within nanodiamonds. By dominating the system with the atomic like resonant force we aim to provide an enhanced trapping force that can be both attractive and repulsive allowing for novel trapping and opto-mechanical cooling schemes. In this talk, I specifically investigate the limitations of using the negatively charged Nitrogen Vacancy centre for this process due to fluorescence quenching induced by the near infrared trapping laser mediated by an increase in charge state interconversion.
