报道了一种新型的聚乙二醇二丙烯酸酯（PEGDA）水凝胶微机器人。这种圆盘状的微型机器人是由激光诱导气泡光热驱动的。一个脉冲激光器被用来顺利地驱动一个80微米直径的气泡microrobot在高达320 μ m s（-1）。一个微型机器人或一对微型机器人合作工作，用于组装20 μ m直径的聚苯乙烯珠成不同的模式。微型机器人也被用来组装由单个酵母细胞和载有细胞的琼脂糖微凝胶制成的图案。培养图案化的酵母细胞和载有细胞的微凝胶，细胞成功繁殖。
A novel hydrogel microrobot made of poly(ethylene glycol) diacrylate (PEGDA) is reported. This disk-shaped microrobot is optothermally actuated by laser-induced bubbles. A pulsed laser is used to smoothly actuate an 80-mu m-diameter bubble microrobot at up to 320 mu m s(-1). A single microrobot or a pair of microrobots working in cooperation were used to assemble 20-mu m-diameter polystyrene beads into different patterns. The microrobots were also used to assemble patterns made of single yeast cells and cell-laden agarose microgels. The patterned yeast cells and cell-laden microgels were cultured, and the cells successfully multiplied.
