Photonic pressure is a consequence of the quantum mechanical properties of light. When photons, which are packets of electromagnetic energy, strike a material, they impart momentum to that material. This transfer of momentum generates a force. The magnitude of this force depends on the intensity, wavelength, and angle of incidence of the light. In the context of nanotechnology, this force can be harnessed to manipulate nanoparticles and other nanoscale objects.
