Abstract

The use of laser microbeams and optical tweezers in a wide field of biological applications from genomic to immunology is discussed. Microperforation is used to introduce a well-defined amount of molecules into cells for genetic engineering and optical imaging. The microwelding of two cells induced by a laser microbeam combines their genetic outfit. Microdissection allows specific regions of genomes to be isolated from a whole set of chromosomes. Handling the cells with optical tweezers supports investigation on the attack of immune systems against diseased or cancerous cells. With the help of laser microbeams, heart infarction can be simulated, and optical tweezers support studies on the heartbeat. Finally, laser microbeams are used to induce DNA damage in living cells for studies on cancer and ageing.

激光微束剪刀与光镊对细胞的操纵研究进展
讨论了激光微光束和光镊在从基因组学到免疫学等广泛的生物学应用领域中的应用。微穿孔用于向细胞中引入一定量的分子,用于基因工程和光学成像。激光微束诱导的两个细胞的微焊接结合了它们的基因装备。显微解剖允许从一整套染色体中分离出基因组的特定区域。用光学镊子处理细胞有助于研究免疫系统对病变细胞或癌细胞的攻击。在激光微光束的帮助下,心脏梗塞可以模拟,光学镊子支持对心跳的研究。最后,激光微束被用来诱导活细胞的DNA损伤,用于癌症和衰老的研究。

期刊介绍: Reports on Progress in Physics is a highly selective journal with a mission to publish ground-breaking new research and authoritative invited reviews of the highest quality and significance across all areas of physics and related areas. Articles must be essential reading for specialists, and likely to be of broader multidisciplinary interest with the expectation for long-term scientific impact and influence on the current state and/or future direction of a field.
