Biotechnologists, physicists, and medical researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed technology for microscopic imaging in living organisms. A miniaturised multi-photon microscope, which could be used in an endoscope in future, excites the body’s own molecules to illuminate and enables cells and tissue structures to be imaged without the use of synthetic contrast agents. The findings have now been published in the renowned journal Advanced Science.
It is often necessary to examine tissue samples under the microscope to diagnose diseases. This involves taking such samples using colonoscopy, for example, and applying contrast agents to distinguish different types of tissue effectively. Biotechnologists, physicists and medical researchers at FAU have now developed a process that could greatly simplify examinations of the colon and other organs. They have miniaturised multi-photon microscopy to such an extent as to enable it to be used in endoscopes.
