One flash of red light could check health of bioprinted tissue and implants
Using 3D printers to create complex structures from biocompatible materials that can include living cells has the potential to revolutionize medicine. This process—3D bioprinting—has powered breakthroughs in tissue engineering, medical implants and reconstructive surgery and may ultimately allow for the creation of transplantable human organs.
Researchers have developed a method to embed microscopic phosphorescent sensor particles within 3D bioprinted materials, allowing for real-time, noninvasive monitoring of cell health. These sensor particles absorb red light from an inexpensive LED and emit modified light based on their surroundings, which can be detected using optical equipment.
By coupling the sensors with enzymes that react with specific nutrients like glucose and lactate, researchers can accurately measure these vital biomarkers. A single flash of red light provides chemical data without any invasive procedures, enabling continuous and noninvasive monitoring of engineered tissues or implants. This technology could revolutionize patient care by enabling smaller, implantable sensors for chronic condition management and immediate tissue health analysis for transplant or cancer surgery patients.
The ability to monitor cell health noninvasively would benefit researchers across various fields, including drug development and tissue engineering, potentially leading to improved therapies and the creation of transplantable organs.
