    Abstract: The present invention relates to a system for screening personalized anticancer agents, a method for screening personalized anticancer agents using the system, and an apparatus for screening personalized anticancer agents. When the inventive system for screening personalized anticancer agents is used, an anticancer agent showing an optimal anticancer activity against cancer cells collected from a patient can be selected from a variety of anticancer agents, and it is possible to previously examine a therapeutic response that can appear when the selected anticancer agent is administered into the patient. Thus, the risk of trial and error in cancer therapy can be reduced, and the cost and time required for cancer therapy can be reduced.

  • Patent number: 11266983
    Abstract: Technology for a pillar structure for a biochip is disclosed. The pillar structure for a biochip includes: a substrate portion having a plate structure; an insertion pillar portion formed in one piece with the substrate portion and protruding downward from a lower surface of the substrate portion so as to be inserted into a well; and a compensation pillar portion formed in one piece with the substrate portion, the compensation pillar portion corresponding to the insertion pillar portion and protruding upward from an upper surface of the substrate portion. Therefore, when the pillar structure is cooled during an injection molding process, the substrate portion is prevented from being partially recessed, and when samples are analyzed using microscopic images, accuracy and reliability may be improved.
