In this work, we study and present hollow PhC cavities and characterize them for their trapping stiffness, trapping stability and variation of resonance wavelength due to the presence of various sized single particles in the cavity.Optical trappingSingle particle detectionPhotonic crystal cavitiesFinite element methodsNanocavitytext::conference output::conference proceedings::conference paper
