I’ve been trying to develop a DIY Biology stain for visualising microbes and bacteria for around six months now. I’ve encountered many deadends but I’ve now developed one that works beautifully and for which the ingredients are safe and readily available to non-scientists. The images are poor because the microscope I used didn’t have a dedicated camera and I had to point my camera at the eye piece. But it works!
