**7. Conclusion/summary**

In this chapter, a discussion about COVID-19 treatment methods based on 3D techniques was briefly analyzed. In the first section, platforms that are available for cell culture and its working characteristics were discussed. Later, it continuously discussed organoids, their definition, and their uses in different applications. Further, its use as different organs is described with its use in different stages. Prediction, as well as treating COVID-19, was found to be crucial and also, research plays a major role to put forth hybridizing of any two methods for accurate curing of COVID-19 from a human body. This method utilized 3D exvivo cell culture method to develop organoids and replace them over infected tissues. 3D disease models are previously available invitro and invivo technologies. However, they showed certain limitations and hence, treating viral infection using any stem cell culture and 3D technologies are quite helpful. Summarizing this chapter is based on the demonstration of active replication of human organoids culture system of lungs are found to be more helpful in the treatment of COVID-19. An organoid culture system is previously proposed and then used in a variety of applications. Rather it implemented 3D technologies for the development of cell culture and then replaced defective cells for an effective cure of viral infection.
