Visualization 2: High efficiency fabrication of complex microtube arrays by scanning focused femtosecond laser Bessel beam for trapping/releasing biological cells

Capture of NIH 3T3 cells by the microtube arrays. By aspirating with syringe, cells align at one end of microtubes in the first 30 s, then deform and been sucked in. Originally published in Optics Express on 03 April 2017 (oe-25-7-8144)
