I took some images using a microscope that uses a technique that breaks the light limit, called super-resolution. It allows to show structures smaller than the light we see coming from them. Here the cell’s skeleton (actin filaments, that help cells move and keep everything in place inside it).
@iPabloSB a little more info, for those interested: the microscope uses what’s called structured illumination. It uses a mix of physics and computation to break the limit of light and show about 2 times more resolution than a regular microscope. And the machine is so big that it takes a whole room
