摘要

毫秒激光源现在广泛应用于辅助生殖技术，用于胚泡阶段的滋养外胚层细胞活检。我们研究了红外飞秒激光脉冲（持续时间为280fs，辐射波长为1028nm）在这方面应用的有效性。活检使用标准的显微外科辅助装置-手持移液器进行。脉冲强度为10至65 TW/cm2，能够从不同厚度的生物酸盐中提取细胞。

Biopsy of Embryonic Trophectoderm Cells Using Infrared Femtosecond Laser Pulses

Millisecond laser sources are now widely used in assisted reproductive technologies for the trophectoderm cell biopsy procedure at the blastocyst stage. We have investigated the effectiveness of application for this purpose of infrared femtosecond laser pulses (280 fs duration and 1028 nm radiation wavelength). The biopsy was performed using standard microsurgical assist devices—holding pipettes. Pulses with an intensity of 10 to 65 TW/cm² were shown to be able to extract cells from bioptates of different thickness.
