- Аннотация: We consider laser printing of gel microdroplets – a promising method for microbiology, biotechnology and medicine. In the printing process, small volumes of gel containing living microorganisms are transferred as a result of cavitation caused by the absorption of a short laser pulse in a metal film. However, in such a transfer, certain physical factors arise that can lead to damage and death of biological material. These factors include elevated temperature and pressure, high radiation intensity and some others. Experimental estimates of these parameters are conducted, based on measurements of the acoustic response of laser printing, electron microscopy of the affected areas and the results of high-speed imaging of the transfer process. It is shown that these factors are not a significant limitation for the technology being developed. Laser printing is performed by exposing a metal film to laser pulses with an energy of 5 – 30 uJ and a duration of 8 – 14 ns, the laser beam diameter being 30 mm.
