Nanoparticles find applications in multiple technological and scientific fields, and laser ablation in liquid (LAL) emerged as a versatile methodfor providing colloidal solutions of nanomaterials with various composition, by a low cost, simple, self-standing, and ?green? procedure.However, the use of high energy and high power laser beams is harmful, especially when coupled with flammable or toxic liquids, andin situ operation is required for starting, monitoring the LAL synthesis, and stopping it at the desired point. Here we describe the hardwareand software design and the test results of a system for the production of nanoparticles by laser ablation synthesis in liquid solution (LASiS),which is remotely controllable with a personal computer or a smartphone. In this system, laser energy and solution flux are selectable, andthe synthesis status can be monitored and managed at any time off site. Only commercially available components and software are employed,making the whole apparatus easily reproducible in any LAL laboratory. The system has proven its reliability in various conditions, includingintercontinental remote control experiments. Overall, this apparatus represents a step forward to improve the safety and to more efficientlyexploit the time of people working with LASiS, thus contributing to the increasing demand for off-site real time monitoring of experimentalequipment in many scientific and industrial laboratories, due to safety and efficiency requirements.
