The photoelectric effect in medicine is second only to the military in the field of high technology-intensive applications. Optoelectronics technology in the medical field is mainly used in biochemical analysis, blood analysis, urinalysis, pathology image recognition, gynecological disease screening, a variety of endoscopic imaging, interventional therapy, ophthalmic equipment and digital X-ray imaging, such as DR, CR, medical thermography, medical laser therapy and surgical equipment, and so on, many of the medical instruments and equipment.
Photovoltaic effect for tumor therapy research exploration note
Japanese researchers Higashi et al. reported that they managed to reproduce the photovoltaic effect in tumor cells, and the researchers used this photovoltaic effect to find a new way to effectively kill tumor cells. The researchers designed a porous nanoparticle containing iodine atoms, introduced this nanoparticle into the tumor tissue, and then irradiated the tumor with X-rays for radiation therapy. A long-standing problem with conventional radiotherapy is that most of the X-rays act on the reactive oxygen species produced by water, which makes up 70% of the cell, to indirectly cleave DNA twice.
