Low-cost AI controlled platform for automated high-throughput and precise ultrasonication

Probe-based ultrasonication is widely used for sample preparation: homogenization, dispersion, disruption, shearing, etc. in laboratories. Usually, it’s operated manually that poses tedious and repetitive labor work, noise stress, etc. It also requires placing and operating the instrument in a separate and dedicated room. Automation of the probe ultrasonication can tackle the above challenges and hereby simplify its operation, especially for high-throughput sample processing. Nowadays, automated ultrasonication is limited due to lack of respective robotic platforms and systems compatible with probe-based ultrasonication instruments. NMBU is developing a low-cost fully automatic platform for probe ultrasonication by introducing customized function modules and AI control algorithms. This novel automated solution can process multiple samples that are randomly located in standard well plates by only pressing ‘start’ and ‘confirm’ on a touch screen. The probe cleaning, temperature control, and ultrasonication process control are automatically performed. The platform is under internal and external testing with various samples and also to be compared with the alternative sample homogenization process like beads beating.
