摘要
20世纪90年代以来,一系列的电子学和光子学技术突破使得太赫兹(THz)技术从实验研究逐渐发展到非破坏性检测、安全、医疗、通信等重要领域的实际应用。新技术的发展广泛激发了研究太赫兹波与生物分子和组织间相互作用的兴趣。与此同时,尽管太赫兹技术得到了广泛应用,人们对太赫兹辐射的生物效应却知之甚少。可以肯定,与高能辐射(如紫外线、X射线、伽马射线等)和生物组织的相互作用所引起的生物损伤相比,太赫兹辐射将引起独特的非电离非热生物效应。本文介绍了生物介质的太赫兹波表征技术研究和生物效应研究,总结了太赫兹技术在生物医学中的最新进展,进一步分析了太赫兹生物医学未来的发展和所面临的关键科学问题。
Since early 1900s, a number of technical breakthroughs in electronics and photonics have started to bring terahertz（THz） wave technologies from laboratory demonstrations to industrial applications such as non-destructive testing, security, medicine, communications, etc. Recent advances in producing TI-Iz radiation have stimulated interests in studying the interaction between radiation and biological molecules and tissue. Despite this emerging ubiquity of THz applications, relatively little is known about the effect of THz radiation on biological systems. It is clear that the non-thermal mechanisms by which the non-ionizing THz radiation influences biological functions must be fundamentally different from those at play when high-energy（UV, X-ray, gamma, et al） radiation interacts and damages hio-matter. The latest application progresses of terahertz technique on biomedicine are overviewed by two parts： advances in characterization techniques and biological effects. Furthermore, the future trends and the key scientific problems of THz-hiomedicine are also pointed out.
