Glass substrate after femtosecond laser irradiation of six devices that will be obtained by six cuts along the transversal straight lines and a further orthogonal one. Chemical etching will create microโchannels where the more complex structures have been irradiated, while not affecting the inscribed optical waveguides. The devices will then be used for optical trapping and stretching of cells. (Picture: F. Bragheri et al., pp. 234โ243 in this issue)
