What is optical coherence tomography?
Optical coherence tomography (OCT) is a non-invasive imaging technique that provides high-resolution, three-dimensional images of biological tissues.
How do tumor spheroids differ from 2D cultures?
Tumor spheroids better mimic the in vivo environment of tumors, allowing for more accurate studies of tumor behavior and drug responses.
What are the advantages of using OCT in this research?
OCT allows for rapid imaging and characterization of tumor spheroids without the need for labeling, providing real-time insights into their growth and structure.
What is the significance of dead tissue detection?
Detecting dead tissue within tumor spheroids can help assess the effectiveness of anti-cancer treatments and improve therapeutic strategies.
How can this research impact drug discovery?
By providing more relevant data on tumor behavior, this research can help streamline the drug discovery process, making it faster and more cost-effective.
