During this CBL course the students will work together in groups to solve a biomedical challenge using optical microscopy. The challenge is in the form of a sample to be imaged to answer a scientific question in the fields of regenerative medicine, cell and tissue biology, molecular diagnostics and nanomedicine. You will have to design, build, calibrate and use an optical microscope consisting of a 3D-printed modular scaffold incorporating the lenses, a camera and the electronics to control and operate the device. The microscope you build and the results of your research will be presented in the form of a poster session with a pitch presentation.
