“…Since the first practical laser traps of micrometer sized particles demonstrated by Ashkin in 1970 [1], optical tweezer has become powerful tools to capture and manipulate various objects, arising from its unique noncontact and noninvasive advantages [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Recently, light-induced rotation [20][21][22][23][24][25] attracts great attentions due to some practical and useful applications ranging from micro-rotors [26] to optical spanners [27], as well as cell orientation [28] and photonic devices [10].…”
