Compared with traditional chemotherapy and radiation therapy, immunotherapy uses the immune system to fight the tumor, with less toxic side effects and more effective treatment. Among them, immunogenic cell death can activate the human immune system through dead cell antigen to achieve immunotherapy. At present, small molecule drugs have been used in clinical treatment of immunogenic cell death, however, how to accurately control the induced immunogenic cell death in the treatment of tumor is of

Recently, under the guidance of Academician Zhuang Songlin, the Terahertz Technology Innovation team of the School of Optoelectronics at the University of Shanghai for Science and Technology has proposed for the first time a new integrated terahertz vortex emitter and uses vortex electromagnetic waves with orbital angular momentum (OAM) to detect the speed of the target. The device can tune frequencies and excite OAM beams with different topological charges. The research team used the combined d

Terahertz waves generally refer to electromagnetic waves in the frequency range of 0.1 to 10 THz, between microwave and infrared. Because THZ waves have good temporal and spatial coherence, low photon energy, large transmission capacity and strong penetration ability, THZ waves have irreplaceable scientific and application potential in the fields of precision spectroscopy, radar imaging, biomedicine, national defense security screening, communication sensing and so on.Terahertz radiation source

The superstructure surface is composed of sub-wavelength quasi-two-dimensional microstructure in accordance with a specific arrangement, which can flexibly regulate the wave front of electromagnetic waves to obtain high-quality sub-wavelength and even focus spots that break the diffraction limit, and effectively realize the functions of traditional three-dimensional "volume" functional devices with flat devices, effectively improving the integrability of functional devices. It provides a new sol

Millions of university students in Optics courses learn how electromagnetic light waves can physically propagate through a 3D space, with its electric and magnetic field vectors pointing in different 3D directions. But a light beam is most commonly considered as a transverse wave, where its electric and magnetic field vectors pointing in a 2D plane perpendicular to the direction of propagation. Finding a way to precisely manipulate 3D vectorial fields with its vector pointing in any desired 3D d

Recently, the Terahertz Innovation Research Institute demonstrated an approach to designing multidimensional spin Hall metalens that can flexibly manipulate the spin. The uniqueness and robust approach for manipulating spin photons may have a significant impact on designing ultra-compact and multifunctional devices and spin photonics devices. The relative article titled “Geometric phase for multidimensional manipulation of photonics spin Hall effect and helicity-dependent imaging” was published
