In a very interesting way, authors have carefully moved hydrogel bubbles using lazers. they were able to assemble polystyrene bead in certain directions using microrobots ...quite interesting!

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-mm-diameter bubble microrobot at up to 320 mm s21
. A single microrobot or a pair of microrobots working in cooperation were used to assemble 20-mm-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.
