Jiang Ying's research group completed the independent research and development and patent transfer of qPlus optical coupling scanning probe microscope

Recently, Professor Jiang Ying's research group from the School of Physics of Peking University and the Light Element Advanced Materials Research Center cooperated with Professor Liu Kaihui's research group to independently develop a qPlus optical coupling scanning probe microscope

Scanning probe microscopy (SPM) is one of the greatest inventions in the field of nanotechnology.

Recently, Peking University signed a contract with a domestic instrument company on the transfer of related patents, involving two utility model patents including "a qPlus-based optically coupled scanning probe microscope", and is actively promoting high-end scanning probes with independent intellectual property rights The localization of microscopes is expected to break the long-term international monopoly situation
