主　　题：Mass sensing Optomechanical crystal cavity Phonon lasing 

摘      要：High-sensitivity mass sensors under ambient conditions are essential in various fields such as biological research,gas sensing and environ-mental *** the current work,a phonon lasing enhanced mass sensor was proposed based on an optomechanical crystal cav-ity under ambient *** phonon lasing was harnessed to achieve ultra-high resolution since it resulted in an extremely nar-row mechanical linewidth(less than 10 kHz).Masses with different weights were deposited on the cavity,it is predicted that the maxi-mum resolution for mass sensing can be 65±19 zg,which approaches the mass order of a protein and an *** implies the potential application of the proposed method in the biomedical fields such as oligonucleotide drug delivery area and the Human Proteome Project.
