AI Technical Summary

Technical Problem

Existing virus inactivation methods suffer from uneven virus inactivation, loss of activity in liquid biological products, and difficulty in cleaning, especially in large-scale production where it is difficult to maintain stable ultraviolet penetration and sample activity.

Method used

The system employs a horizontal track and robotic arm-driven flat, light-transmitting container. Through an automated production line with filling, ultraviolet irradiation, collection, and cleaning zones, it ensures uniform liquid layer thickness. Combined with a CNC system and human-machine interface, it achieves automated processing of virus inactivation and liquid biological products.

Benefits of technology

It improves the stability of virus inactivation and the activity retention of liquid biological products, reduces denaturation adhesion and light transmittance reduction, and achieves a highly efficient, automated and easy-to-clean virus inactivation process.
