    "abstract": "Analytical solution for optical trapping force on a spherical dielectric\nparticle for an arbitrary positioned focused beam is presented in a generalized\nLorenz-Mie and vectorial diffraction theory. In this case the exact\nelectromagnetic field is considered in the focal region. A double tweezers\nsetup was employed to perform ultra sensitive force spectroscopy and observe\nthe forces, demonstrating the selectively couple of the transverse electric\n(TE), transverse magnetic (TM) modes by means of the beam polarization and\npositioning, and to observe correspondent morphology-dependent resonances (MDR)\nas a change in the optical force. The theoretical prediction of the theory\nagrees well with the experimental results. The algorithm presented here can be\neasily extended to other beam geometries and scattering particles.",
