Abstract

A method for sensing a target object using optical mode excitations in microresonators, comprises: preparing at least one cluster including at least two microresonators; obtaining some first spectra of the cluster; adsorbing the target object on a surface of the cluster; obtaining some second spectra of the cluster; and sensing the target object by comparing a lineshape of the first spectra with a lineshape of the second spectra.
