RESUMO
The terahertz wave frequency is located between macroscopic electronics and microphotonics.Therefore,this kind of radiation exhibits both photonic properties and electronic characteristics,and thus has great application potentials.So far,important breakthroughs have been achieved in developing terahertz sources and detection technologies.It is believed that the terahertz wave may lead to revolutionary development,especially in the field of biomedicine.Recently,the radiation effects of terahertz wave on biological activities have become a major issue in the field of life sciences,however,it is still at an initial stage worldwide.Therefore,this paper reviewed the physical characteristics and biological effects of terahertz wave and aimed to provide a reference for further medical studies of terahertz wave.
